Building Pressurization Control (VFD)  
Trane’s Statitrac™ control is a highly  
accurate and efficient method of  
maintaining building pressure control  
with a large rooftop air conditioner.  
Variable Frequency Drives are factory  
installed and tested to provide supply/  
exhaust fan motor speed modulation.  
VFD’s, as compared to inlet guide vanes  
or discharge dampers, are quieter, more  
efficient, and are eligible for utility  
rebates.The VFD’s are available with or  
without a bypass option. Bypass control  
will simply provide full nominal airflow  
in the event of drive failure.  
Com fort Control  
The efficiency is achieved with a 100  
percent modulating exhaust system with  
two forward-curved fans with  
The modular control design of the UCM  
allows for greater application flexibility.  
Customers can order exactly the options  
required for the job, instead of one large  
control package. Unit features are  
distributed among multiple field  
replaceable printed circuit boards.The  
Trane UCM can be set up to operate  
under one of three control applications:  
1) stand-alone  
modulating discharge dampers that  
operate only when needed, compared to  
some systems that operate continually.  
And most of the operating hours of the  
100 percent modulating exhaust system  
are at part load, saving more energy.  
Trane’s Statitrac, with the 100 percent  
modulating exhaust system, provides  
comfort and economy for buildings with  
large rooftop air conditioning systems.  
2) interface withTrane’sTracer® building  
management system  
3) interface with a generic (non-Trane)  
building management system. All set-up  
parameters are preset from the factory,  
requiring less start-up time during  
installation.  
Statitrac control is simple!The space  
pressure control turns the exhaust fans  
on and off as required and modulates  
exhaust dampers to maintain space

demand limiting type, night setback  
setpoints, and many other setpoints. No  
potentiometers are required for setpoint  
adjustment, all adjustments are done  
through the Remote Human Interface  
key-pad. Also up to 48 different rooftop  
diagnostic points can be monitored  
through the human interfaces such as:  
sensor failures, loss of supply airflow,  
and compressor trip. No special tools are  
required for servicing of the unit. All  
diagnostic displays are available in clear  
English at the Remote Human Interface  
and will be held in memory, so that the  
operator/servicer can diagnose the root  
cause of failures.  
The Statitrac™ direct space building  
control sequence will be maintained  
when a variable frequency drive is used.  
Fans With Inlet Guide Vanes  
Trane’s forward curved fans (20 through  
75 tons) and air foil fans (90 through 130  
tons) with inlet guide vanes pre-rotate  
the air in the direction of the fan wheel,  
decreasing static pressure and  
horsepower, essentially unloading the  
fan wheel.The unloading characteristics  
of a Trane FC fan with inlet guide vanes  
result in superior part load performance.

compressors have undergone more  
Fewer parts than an equal capacity  
reciprocating compressor means  
significant reliability and efficiency  
benefits.The single orbiting scroll  
eliminates the need for pistons,  
connecting rods, wrist pins and valves.  
Fewer parts lead to increased reliability.  
Fewer moving parts, less rotating mass  
and less internal friction means greater  
efficiency than reciprocating  
compressors.  
TheTrane 3-D Scroll provides important  
reliability and efficiency benefits.The 3-D  
Scroll allows the orbiting scrolls to touch  
in all three dimensions, forming a  
completely enclosed compression  
chamber which leads to increased  
efficiency. In addition, the orbiting scrolls  
only touch with enough force to create a  
seal; there is no wear between the scroll  
plates.The fixed and orbiting scrolls are  
made of high strength cast iron which  
results in less thermal distortion, less  
leakage, and higher efficiencies. The  
most outstanding feature of the 3-D  
Scroll compressor is that slugging will  
not cause failure. In a reciprocating  
compressor, however, the liquid or dirt  
can cause serious damage.  
Low Torque Variation  
The 3-D Scroll compressor has a very  
smooth compression cycle; torque  
variations are only 30 percent of that  
produced by a reciprocating compressor.  
This means that the scroll compressor  
imposes very little stress on the motor  
resulting in greater reliability. Low torque  
variation reduces noise and vibration.  
Suction Gas Cooled Motor  
Compressor motor efficiency and  
reliability is further optimized with the  
latest scroll design. Cool suction gas  
keeps the motor cooler for longer life and  
better efficiency.

distinguishing feature of the scroll  
compressor.

When is it necessary to provide building  
exhaust? Whenever an outdoor air  
economizer is used, a building generally  
requires an exhaust system.The purpose  
of the exhaust system is to exhaust the  
proper amount of air to prevent over or  
underpressurization of the building.The  
goal is to exhaust approximately 10  
percent less air than the amount of  
outside air going into the building.This  
maintains a slightly positive building  
pressure.

Because discharge dampers modulate  
the airflow, the exhaust fan may be  
running unloaded whenever the  
economizer dampers are less than 100  
percent open.  
100 percent modulating exhaust with  
Statitrac™ control  
For both CV and VAV rooftops, the 100  
percent modulating exhaust discharge  
dampers (or VFD) are modulated in  
response to building pressure. A  
differential pressure control system,  
called Statitrac™, uses a differential  
pressure transducer to compare indoor  
building pressure to atmospheric  
With an exhaust fan system, the supply  
fan must be sized to pull the return air  
back to the unit through the return  
system during non-economizer  
operation. However, a supply fan can  
typically overcome return duct losses  
more efficiently than a return air fan  
system. Essentially, one large fan by itself  
is normally more efficient than two fans  
in series because of only one drive loss  
not two as with return air systems.

this fan is controlled by modulating  
discharge dampers at the fan outlet.The

100 Percent Exhaust System  
Competitive rooftops use a return air fan  
system for controlling the amount of  
exhaust air during economizer  
operation.The return fan is in series with  
the supply fan and must operate  
pressurized when economizer operation  
is allowing lesser amounts of outdoor air  
into the building. If, however, building  
pressure is not of a critical nature, the  
non-modulating exhaust system may be

whenever the supply fan is operating.  
During economizer operation, the  
economizer outdoor air dampers control  
the position of the return and exhaust air  
dampers, to exhaust the proper amount  
of air.The disadvantage of a return air  
fan is that it runs continuously, versus an  
exhaust fan system which runs only  
when needed to lower or maintain  
building static pressure. Also, the return  
fan must discharge air in two directions,  
through the return air dampers and/or  
exhaust air dampers, resulting in less  
efficient operation compared to an  
exhaust fan.

Barometric Relief Dampers  
50 Percent Exhaust System  
Barometric relief dampers consist of  
gravity dampers which open with  
increased building pressure. As the  
building pressure increases, the pressure  
in the unit return section also increases,  
opening the dampers and relieving air.  
Barometric relief may be used to provide  
relief for single story buildings with no  
return ductwork and exhaust  
The 50 percent exhaust system is a  
single FC exhaust fan with half the air-  
moving capabilities of the supply fan  
system.The experience ofTheTrane  
Company is that a non-modulating  
exhaust system selected for 40 to 50  
percent of nominal supply CFM can be  
applied successfully.  
The IntelliPak® Rooftop unit offers  
modulating 100 percent exhaust system.  
This fan system has performance  
capabilities equal to the supply fan.The

Considerations  
Figure AC-3 is a simplified sketch  
because of the location of the heating

much the same way as on S*HFs by  
removing the exhaust fan access door  
(Panel B). SeeTables AC-4 and 5 for  
S*HG panel dimensions.  
perimeter to facilitate ductwork  
showing which panels can be used for  
horizontal supply and/or return. On 90 to  
130 ton units, only one side of the  
extended casing may be used for  
horizontal supply because of the  
location of the unit control panel.There  
are, however, on SXHF models two  
panels (Panels A) on the side opposite  
the control box which can be removed  
along with the vertical support which  
separates the two. Removal of the  
vertical support is optional, but will  
ensure maximum airflow. On SLHG,  
SSHG models only one of the Panel A’s  
may be used for horizontal supply  
attachment. If exhaust fans are being  
used on an IntelliPak Rooftop unit with  
horizontal return, provisions should be  
made for access to the exhaust  
components, since the access door  
opening is now being used as a return.  
Perhaps the return ductwork attachment  
to the rooftop can include a section of  
removable duct. Use the dimensions  
provided and the supply and exhaust  
CFM to calculate the velocity (ft/min)  
through the openings.  
When using an IntelliPak® Rooftop for  
horizontal supply and return, an  
additional pressure drop must be added  
to the supply external static to account  
for the 90 degree turn the air is making.  
This additional pressure drop depends  
on airflow and rooftop size, but a range  
of 0.10 inches to 0.30 inches can be  
expected.The openings on the rooftop  
all have a one inch lip around the  
Horizontal Discharge SXHG, SLHG,  
SSHG Rooftops (90 to 130 tons)  
The SXHG, SLHG, SSHG rooftops can be  
field modified to supply and return air  
Figure AC-3 — Horizontal Discharge Panel Dimensions — 90 - 130Tonss SXHG, SLHG, SSHG Units horizontally without the use of a  
horizontal supply/return curb.  
To supply air horizontally, use Panel A  
only.The Panel on the opposite side  
cannot be used due to the location of the  
unit control Panel. SXHG rooftop air  
conditioners do not have a panel  
configuration like the 20 to 75 ton  
rooftops.To achieve maximum airflow,  
vertical support can be removed after the  
unit has been placed on the roof curb. It  
is secured by four screws. (See Note 1)  
For horizontal discharge on SLHG and  
SSHG units, only the Panel A next to the  
condenser fan section can be removed.  
The other Panel A next to the supply fan  
cannot be used due to the location of the  
heating coils.  
To return air horizontally, the exhaust fan  
access door (Panel B) can be removed  
and used as a return opening.  
Note:

Application  
Considerations

depending on the hours of use, the  
quality of maintenance performed, and  
the regularity of that maintenance. One  
factor that can have an adverse effect on  
unit life is its operation in a corrosive  
environment.  
CV and VAV IntelliPak® Rooftops. For  
your convenience the sequences can be  
factory preset or fully field editable from  
the Human Interface Panel orTracer®.  
Any or all five sequences may be  
“locked” in by the user at the Human  
Interface Panel.  
Rooftops are popular because of their  
“packaged” nature. Everything needed  
is contained in one box; mix-matching is  
neither necessary nor available. With this  
convenience comes some  
disadvantages; one is the rooftop’s  
cooling capacity may not exactly match  
the building load. It is conceivable that a  
50 ton rooftop would need to be used on  
an application that is 41 tons, simply  
because the 40 ton rooftop does not  
meet capacity.  
When rooftops are operated in corrosive  
environments,Trane recommends that  
copper fins be utilized on the condenser  
and/or evaporator coil. Because copper  
is more resistant to corrosion than  
aluminum, coil life expectancy is greatly  
increased. Some industry applications  
expose equipment to corrosive agents  
that even copper cannot fully resist. For  
those special applications, a baked  
phenolic resin coating (i.e. Heresite) is  
highly desirable. Baked phenolic  
The user can customize up to five (5)  
different override sequences for  
purposes such as smoke control.The  
following parameters within the unit can  
be defined for each of the five  
sequences:  
• Supply Fan — on/off  
• Inlet Guide Vanes — open/closed/  
controlling  
In order to avoid such occurrences, and  
to more closely match the rooftop’s  
capacity to the building load, a high  
capacity evaporator coil option is  
• Variable Frequency Drives — on (60  
Hz)/off (0 Hz)/controlling  
available on all IntelliPak® Rooftops 20 to  
105 tons.These high capacity coils have  
an increased number of evaporator coil  
rows as compared to standard and  
enhanced evaporator tube surfaces,  
resulting in a higher capacity. Capacity  
tables for both standard and high  
capacity coils are available in the cooling  
data section of this catalog. SeeTable  
PD-43 for the pressure drops associated  
with the high capacity coil option.This  
pressure drop should be added to the  
total static pressure used to size the  
supply fan motor.

Ventilation Override Sequences  
One of the benefits of using an exhaust  
fan rather than a return fan, in addition  
to the benefits of lower energy usage  
and improved building pressurization  
control, is that the rooftop can be used  
as part of a ventilation override system.  
Several types of sequences can be easily  
done when exhaust fans are a part of the  
rooftop system.  
Compressors and condenser fans are  
shut down for anyVentilation Override  
sequence. Factory preset sequences  
include unit Off, Exhaust, Purge, Purge  
with duct pressure control, and  
Pressurization. Any of the user-defined  
Ventilation Override sequences can be  
initiated by closing a field supplied  
switch or contacts connected to an input  
on the Ventilation Override Module. If  
more than one ventilation override  
sequence is being requested, the  
sequence with the highest priority is  
initiated. Refer to the Sequence of  
Operation provided in the Control  
section of this catalog for more details  
on each override sequence.  
Low Ambient Operation — Human  
Interface Recommendations  
What would initiate the ventilation  
override control sequence?Typically, a  
manual switch is used and located near  
the fire protection control panel.This  
enables the fire department access to the  
control for use during or after a fire. It is  
also possible to initiate the sequence  
from a field-installed automatic smoke  
detector. In either case, a contact closure  
begins the ventilation override control  
sequence. CAUTION!: The ventilation  
override system should not be used to  
signal the presence of smoke caused by  
a fire.  
Who wants to be on a roof at sub-zero  
temperatures? We can understand a  
service technician’s reluctance to do this;  
that’s why we recommend using a  
remote mounted Human Interface Panel.  
The service technician can troubleshoot  
and diagnose in the comfort of a  
mechanical room.  
Natural Gas Heating Considerations  
The IntelliPak standard, or limited  
modulation, gas heat exchangers are not  
recommended for applications with  
mixed air conditions entering the heat  
exchanger below 50°F. Mixed air  
temperatures below 50°F can cause  
condensation to form on the heat

For increased reliability, the  
recommendation in these applications is

limitations and temperature rise across

Table PD-24, 25 and RT-EB-104.  
It is impossible to totally quantify the  
effect of building structure on sound  
transmission, since this depends on the  
response of the roof and building  
members to the sound and vibration of  
the unit components. However, the  
guidelines listed above are experience  
proven guidelines which will help reduce  
sound transmission.  
maintained to assure adequate  
serviceability, maximum capacity and  
peak operating efficiency. A reduction in  
unit clearance could result in condenser  
coil starvation or warm condenser air  
recirculation. If the clearances shown are  
not possible on a particular job, consider  
the following:  
• Do the clearances available allow for  
major service work such as changing  
compressors or coils?  
• Do the clearances available allow for  
proper outside air intake, exhaust air  
removal and condenser airflow?  
• If screening around the unit is being  
used, is there a possibility of air  
recirculation from the exhaust to the  
outside air intake or from condenser  
exhaust to condenser intake?  
Acoustical Considerations  
The ideal time to make provisions to  
reduce sound transmission to the space  
is during the project design phase.  
Proper placement of rooftop equipment  
is critical to reducing transmitted sound  
levels to the building.The most  
economical means of avoiding an  
acoustical problem is to place any  
rooftop equipment away from  
acoustically critical area. If possible,  
rooftop equipment should not be located  
directly above areas such as: offices,  
conference rooms, executive office areas  
and classrooms. Ideal locations are  
above corridors, utility rooms, toilet  
facilities, or other areas where higher  
sound levels are acceptable.  
There are several other sources of unit  
sound, i.e., supply fan, compressors,  
exhaust fans, condenser fans and  
aerodynamic noise generated at the duct  
fittings. Refer to the ASHRAE  
Applications Handbook, Chapter 42, 1991  
edition for guidelines for minimizing the  
generation of aerodynamic noise  
associated with duct fittings.  
Trane’s Engineering Bulletin RT-EB-80  
describes various duct installation  
considerations specifically addressing  
indoor sound level concerns.This  
bulletin includes sound power data on  
Trane’s IntelliPak Rooftops 20 to 130 tons.  
Ask your localTrane representative for  
this informative engineering bulletin.  
Actual clearances which appear  
inadequate should be reviewed with a  
localTrane sales engineer.  
When two or more units are to be placed  
side by side, the distance between the  
units should be increased to 150 percent  
of the recommended single unit  
clearance.The units should also be  
staggered as shown in Figure AC-4 for  
two reasons:  
Several basic guidelines for unit  
placement should be followed to  
minimize sound transmission through  
the building structure:  
The VariTrane® Computerized Duct  
Design Program can be used to analyze  
the truck duct, run-out duct, VAV control  
unit and terminal unit noise attenuation.

in each terminal so that the designer can

Duct Design  
Figure AC-4 — Unit Placement  
It is important to note that the rated  
capacities of the rooftop can be met only  
if the rooftop is properly installed in the  
field. A well-designed duct system is  
essential in meeting these capacities.  
1
The satisfactory distribution of air  
throughout the system requires that  
there be an unrestricted and uniform  
airflow from the rooftop discharge duct.  
This discharge section should be straight  
for at least several duct diameters to  
allow the conversion of fan energy from  
velocity pressure to static pressure.

50 - 75 ton m odels have two outdoor air intakes.  
2. 90-130 ton m odels have two outdoor air intakes on  
the backside of the unit and one sm all air intake at  
the end of the unit.  
However, when job conditions dictate  
elbows be installed near the rooftop  
outlet, the loss of capacity and static  
pressure may be reduced through the  
use of guide vanes and proper direction  
of the bend in the elbow.The high  
velocity side of the rooftop outlet should  
be directed at the outside radius of the  
elbow rather than the inside as  
illustrated in Figure AC-5.

Selection  
Procedure  
This section outlines a step-by-step  
procedure that may be used to select a

sample selection is based on the  
following conditions:  
• Summer outdoor design conditions —  
95 DB/76 WB ambient temperature  
• Summer room design conditions —78  
DB/65 WB  
• Total cooling load — 430 MBh (35.8

Table PD-9, a 50 ton unit capacity with  
standard capacity evaporator coil at  
80 DB/65 WB, 95 F outdoor air

is 551 MBh total and 422 MBh sensible.  
Thus, a nominal 50 ton unit with  
standard capacity evaporator coil  
is selected.  
Using total of 17,500 cfm and total  
static pressure of 2.76 inches, enterTable

From Table PD-31, select the low heat  
module. By interpolation, a Q/ITD of 4.50  
can be obtained at a gpm at 25.7.  
Gas Heating System (Natural Gas)  
From Table PD-26, select the high heat  
module.The high heat module at 17,500  
cfm has a Q/ITD = 5.11.  
Heat module capacity, Q = ITD x Q/ITD =  
185 F x 5.11 Q/ITD = 945 MBh  
From Table PD-24 select the high heat  
module (697 MBh output) to satisfy  
winter heating load of 563 MBh at unit  
cfm.  
Water pressure drop at 25.7 gpm is 0.57  
ft. of water. Heat module temperature  
rise is determined by:  
Table PD-26 also shows an air  
temperature rise of 36.0 F for 17,500 cfm  
through the heating module.

Unit supply temperature at design  
heating conditions = mixed air  
temperature + air temperature rise = 65.4

1.085 x Supply cfm  
(1.085 x 17,500)  
945 Btu ÷ (1.085 x 17,500 cfm) = 49.8 F.  
Unit supply air temperature = mixed air  
temperature + air temperature rise = 65.4  
+ 29.7 = 95 F.  
Unit supply temperature at design  
conditions = mixed air temperature + air  
temperature rise = 65.4 F + 49.8 F = 115 F.  
Hot Water Heating  
Steam Heating System  
Assume a hot water supply temperature  
of 190 F. Subtract the mixed air  
temperature from the hot water  
temperature to determine the ITD (initial  
temperature difference).  
Assume a 15 psig steam supply.  
From Table PD-27, the saturated  
temperature steam is 250 F. Subtract  
mixed air temperature from the steam

Selection  
Procedure  
AIR DELIVERY PROCEDURE  
UNIT ELECTRICAL REQUIREMENTS  
Supply fan performance tables include  
internal resistance of rooftop. For total  
static pressure determination, system  
external static must be added to  
appropriate component static pressure  
drop (evaporator coil, filters, optional  
economizer, optional exhaust fan,  
optional heating system, optional  
cooling only extended casing, optional  
roof curb).  
Selection procedures for electrical  
requirements for wire sizing amps,  
maximum fuse sizing, and dual element  
fuses are given in the electrical service  
section of this catalog.  
Altitude Corrections  
The rooftop performance tables and  
curves of this catalog are based on  
standard air (.075 lbs/ft). If the rooftop  
airflow requirements are at other than  
standard conditions (sea level), an air  
density correction is needed to project  
accurate unit performance.  
Supply Fan Motor Sizing  
The supply fan motor selected in the  
cooling capacity determination was 15.3  
bhp and 924 rpm.Thus, a 20 hp supply  
fan motor is selected. EnterTable PD-45  
to select the proper drive. For a 50 ton  
rooftop with 20 hp motor, a drive  
Figure PAF-1 shows the air density ratio  
at various temperatures and elevations.  
Trane rooftops are designed to operate  
between 40 and 90 degrees Fahrenheit  
leaving air temperature.  
number 9 — 900 rpm is selected.  
Exhaust Fan Motor Sizing  
The procedure to use when selecting a  
supply or exhaust fan on a rooftop for  
elevations and temperatures other than  
standard is as follows:  
The exhaust fan is selected based on  
total return system negative static  
pressure and exhaust fan cfm. Return  
system negative static include return  
duct static and roof curb static pressure  
drop.  
1
First, determine the air density ratio  
using Figure PAF-1.  
Return duct static pressure = 0.65 inches  
2
Trane roof curb (Table PD-43) = 0.12  
inches  
Divide the static pressure at the  
nonstandard condition by the air  
density ratio to obtain the corrected  
static pressure.  
Total return system negative static  
pressure = 0.77 inches  
Exhaust fan cfm = 12,000 cfm  
3
From Table PD-47, the required bhp is  
3.45 hp at 574 rpm.Thus, the exhaust fan  
motor selected is 5 hp.  
Use the actual cfm and the corrected  
static pressure to determine the fan rpm  
and bhp from the rooftop performance  
tables or curves.  
To select a drive, enterTable PD-49 for a 5  
hp motor for a 50 ton unit. Drive  
selection number 6 — 600 rpm.  
4
The fan rpm is correct as selected.  
Where altitudes are significantly above  
sea level, useTables PAF-2 and PAF-3 and  
Figure PAF-1 for applicable correction  
factors.  
5
Bhp must be multiplied by the air  
density ratio to obtain the actual  
operating bhp.

RT-PRC010-EN  
Selection  
Procedure  
In order to better illustrate this  
procedure, the following example is  
used:  
HEATING CAPACITY SELECTION  
Step 1 — Determine AirTemperature  
Entering Heating Module  
Consider a 60 ton rooftop unit that is to  
deliver 18,000 actual cfm at 3-inches total  
static pressure (tsp), 55 F leaving air  
temperature, at an elevation of 5,000 ft.  
Mixed air temperature = RADB + % OA  
(OADB - RADB) = 70 + (0.10) (0 - 70) = 63  
F
Supply air fan motor heat temperature  
rise = 46,000 Btu ÷ (1.085 x 17,500 cfm) =  
2.42 F  
1
From Figure PAF-1, the air density ratio is  
0.86.  
Air temperature entering heating  
module = 63.0 + 2.42 = 65.4 F  
2
Tsp = 3.0-inches / 0.86 = 3.49 inches tsp.  
3
From the performance tables: a 60 ton  
rooftop (without inlet vanes) will deliver  
18,000 cfm at 3.49-inches tsp at 906 rpm  
and 21.25 bhp.  
4
The rpm is correct as selected - 906 rpm.  
5
Bhp = 21.25 x 0.86 = 18.3 bhp actual.  
Compressor MBh, SHR, and kw should  
be calculated at standard and then  
converted to actual using the correction  
factors inTable PAF-2. Apply these factors  
to the capacities selected at standard cfm  
so as to correct for the reduced mass  
flow rate across the condenser.  
Heat selections other than gas heat will  
not be affected by altitude. Nominal gas  
capacity (output) should be multiplied by  
the factors given inTable PAF-3 before  
calculating the heating supply air  
temperature.

Notes:  
1. Fan perform ance for 20 and 25 ton rooftops is identical. However, note m axim um m otor hp size for each size. Contact your local Trane representative for  
inform ation on oversized m otors.  
2. Shaded areas at table extrem es note non-standard Bhp or Rpm selection. Contact your local Trane representative for m ore inform ation.  
3. Supply fan perform ance table includes internal resistance of rooftop. For total static pressure determ ination, system external static m ust be added to appropriate  
com ponent static pressure drops (evaporator coil, filters, optional econom izer, optional exhaust fan, optional heating system , optional cooling only extended  
casing, optional roof curb).  
4. Maxim um Cfm (for UL approval) as follows: 20 Ton — 9,000 Cfm , 25 Ton — 11,000 Cfm  
5. Minim um m otor horsepower is 3 hp.  
6. Maxim um m otor horsepower as follows: 20 Ton — 15 hp, 25 Ton — 15 hp  
7. Maxim um 3 hp and 5 hp m otor Rpm is 1,100, m axim um 7.5 hp to 15 hp m otor Rpm is 1655.

Notes:  
1. Fan perform ance for 20 and 25 ton rooftops is identical. However, note m axim um m otor hp size for each size. Contact your local Trane representative for inform ation on  
oversized m otors.  
2. Shaded areas at table extrem es note non-standard Bhp or Rpm selection. Contact your local Trane representative for m ore inform ation.  
3. Supply fan perform ance table includes internal resistance of rooftop. For total static pressure determ ination, system external static m ust be added to appropriate com ponent  
static pressure drops (evaporator coil, filters, optional econom izer, optional exhaust fan, optional heating system , optional cooling only extended casing, optional roof curb).  
4. Maxim um Cfm (for UL approval) as follows: 20 Ton — 9,000, Cfm 25 Ton — 11,000 Cfm .  
5. Minim um m otor horsepower is 3 hp.  
6. Maxim um m otor horsepower as follows: 20 Ton — 10 hp, 25 Ton — 15 hp.  
7. Maxim um 3 hp and 5 hp m otor Rpm is 1,100, m axim um 7.5 hp to 15 hp m otor Rpm is 1655.

Notes:  
1. Fan perform ance for 60, 70 and 75 ton rooftops are identical. However, note m axim um m otor hp size for each size. Contact your local Trane representative for inform ation on  
non-standard m otors.  
2. Shaded areas at table extrem es note non-standard Bhp or Rpm selection. Contact your local Trane representative for m ore inform ation.  
3. Supply fan perform ance table includes internal resistance of rooftop. For total static pressure determ ination, system external static m ust be added to appropriate com ponent  
static pressure drops (evaporator coil, filters, optional econom izer, optional exhaust fan, optional heating system , optional cooling only extended casing, optional roof curb).  
4. Maxim um Cfm (for UL approval) as follows: 60 Ton — 27,000 Cfm , 70 & 75 Ton — 30,000 Cfm  
5. Minim um m otor horsepower is 10 hp.  
6. Maxim um m otor horsepower is 40 hp.  
7. Maxim um m otor Rpm is 1,130.

Notes:  
1. Fan perform ance for 60, 70 and 75 ton rooftops are identical. Contact your local Trane representative for inform ation on non-standard m otors.  
2. Shaded areas at table extrem es note non-standard Bhp or Rpm selection. Contact your local Trane representative for m ore inform ation.  
3. Supply fan perform ance table includes internal resistance of rooftop. For total static pressure determ ination, system external static m ust be added to appropriate com ponent  
static pressure drops (evaporator coil, filters, optional econom izer, optional exhaust fan, optional heating system , optional cooling only extended casing, optional roof curb).  
4. Maxim um Cfm (for UL approval) as follows: 60 Ton — 27,000 Cfm , 70 & 75 Ton — 30,000 Cfm  
5. Minim um m otor horsepower is 10 hp.  
6. Maxim um m otor horsepower is 40 hp.  
7. Maxim um m otor Rpm is 1,130.

Notes:  
1. Shaded areas indicate non-standard BHP or RPM selections. Contact your local Trane representive for m ore inform ation.  
2. Supply fan perform ance table includes internal resistance of rooftop. For total static pressure determ ination, system external static m ust be added to appropriate com ponent  
static pressure drops, (evaporator coil, filters, optional econom izer, optional heating system , optional roof curb).  
3. Maxim um static pressure leaving the rooftop is 4.0’’ H20 positive. The static pressure drops from the supply fan to the space cannot exceed 4.0’’ H20.  
4. Minim um m otor horsepower is 30 hp.  
5. See RT-EB-104 for further details.

Notes:  
1. Shaded areas indicate non-standard BHP or RPM selections. Contact your local Trane representive for m ore inform ation.  
2. Supply fan perform ance table includes internal resistance of rooftop. For total static pressure determ ination, system external static m ust be added to appropriate com ponent  
static pressure drops, (evaporator coil, filters, optional econom izer, optional heating system , optional roof curb).  
3. Maxim um static pressure leaving the rooftop is 4.0’’ H20 positive. The static pressure drops from the supply fan to the space cannot exceed 4.0’’ H20.  
4. Minim um m otor horsepower is 30 hp.  
5. See RT-EB-104 for further details.

Notes:  
1. Shaded areas indicate non-standard BHP or RPM selections. Contact your local Trane representive for m ore inform ation.  
2. Supply fan perform ance table includes internal resistance of rooftop. For total static pressure determ ination, system external static m ust be added to appropriate  
com ponent static pressure drops, (evaporator coil, filters, optional econom izer, optional heating system , optional roof curb).  
3. Maxim um static pressure leaving the rooftop is 4.0’’ H20 positive. The static pressure drops from the supply fan to the space cannot exceed 4.0’’ H20.  
4. Maxim um Cfm as follows: 105 Ton Std. — 44,000 Cfm , 105 Hi-Cap., 115, 130 Ton — 46,000 Cfm  
5. Minim um m otor horsepower is 30 hp.

Notes:  
1. Shaded areas indicate non-standard BHP or RPM selections. Contact your local Trane representive for m ore inform ation.  
2. Supply fan perform ance table includes internal resistance of rooftop. For total static pressure determ ination, system external static m ust be added to appropriate com ponent  
static pressure drops, (evaporator coil, filters, optional econom izer, optional heating system , optional roof curb).  
3. Maxim um static pressure leaving the rooftop is 4.0’’ H20 positive. The static pressure drops from the supply fan to the space cannot exceed 4.0’’ H20.

Cooling/Economizer  
capacity and limit horsepower at lower  
system air requirements. When in any  
position other than full open, the vanes  
pre-spin intake air in the same direction  
as supply fan rotation. As the vanes  
approach the full-closed position, the  
amount of “spin” induced by the vanes  
increases at the same time that intake  
airflow and fan horsepower diminish.  
The inlet guide vanes will close when the  
supply fan is shut down, except during  
night setback.  
NOTE: When noted in this sequence  
“Human Interface Panel,” the reference is  
to both the unit mounted and remote  
mounted Human Interface Panel. All  
setpoint adjustments can be  
accomplished at the unit or Remote  
Human Interface Panel.  
During Occupied cooling mode of  
operation, the economizer (if available)  
and mechanical cooling are used to  
control the supply air temperature.The  
supply air temperature setpoint and  
deadband are user-defined at the Human  
Interface Panel. If the enthalpy of the  
outside air is appropriate to use “free  
cooling,” the economizer will be used  
first to attempt to satisfy the supply air  
setpoint; then if required the mechanical  
cooling will be staged on to maintain  
supply air temperature setpoint.  
Minimum On/Off timing of  
Variable Frequency Drive (VFD) Control  
Variable frequency drives are driven by a  
modulating 0-10 vdc signal from the  
Rooftop Module (RTM). A pressure  
transducer measures duct static  
pressure, and the VFD is modulated to  
maintain the supply air static pressure  
within an adjustable user-defined range.  
The range is determined by the supply  
air pressure setpoint and supply air  
pressure deadband, which are set  
through the Human Interface Panel.  
the mechanical cooling prevents  
rapid cycling.  
On units with economizer, a call for  
cooling will modulate the fresh air  
dampers open.The rate of economizer  
modulation is based on deviation of the  
discharge temperature from setpoint,  
i.e., the further away from setpoint, the  
faster the fresh air damper will open.  
First stage of cooling will be allowed to  
start after the economizer reaches  
full open.  
Variable frequency drives provide supply  
fan motor speed modulation.The drive  
will accelerate or decelerate as required  
to maintain the supply static pressure  
setpoint. When subjected to high  
ambient return conditions the VFD shall  
reduce its output frequency to maintain  
operation. Bypass control is offered to  
provide full nominal airflow in the event  
of drive failure.  
Note that the economizer is only allowed  
to function freely if one of the following  
conditions is met. For dry bulb  
economizer control the ambient  
temperature must be below the dry bulb  
temperature control setting. For  
reference enthalpy economizer control,  
outdoor air enthalpy must be below the  
enthalpy control setting. For comparative  
enthalpy economizer control, outdoor air  
enthalpy must be below the enthalpy of  
the return air.  
Supply Air Static Pressure Limit  
The opening of the inlet guide vanes and  
VAV boxes are coordinated during unit  
start up and transition to/from Occupied/

reset based on outdoor air temperature  
Outdoor air cooling reset is sometimes  
used in applications where the outdoor  
temperature has a large effect on  
building load. When the outside air  
temperature is low and the building  
cooling load is low, the supply air  
setpoint can be raised, thereby  
preventing subcooling of critical zones.  
This reset can lower usage of  
mechanical cooling, thus savings in  
compressor KW, but a increase in supply  
fan KW may occur.

Daytime warm-up  
This feature is available on all types of

allows the user to set (calibrate) the

guide vanes (or VFD) at 0 percent and at  
100 percent. On units with inlet guide  
vanes (or VFD) and economizer, the  
minimum position of the economizer is  
modulated based on inlet guide vane  
position (or VFD speed).  
reset based on zone temperature  
Zone reset is applied to the zone(s) in a  
building that tend to overcool or  
overheat.The supply air temperature  
setpoint is adjusted based on the  
temperature of the critical zone(s).This  
can have the effect of improving comfort  
and/or lowering energy usage.The user-  
defined parameters are the same as for  
outdoor air reset.  
As the heating requirement is satisfied,  
the UCM will reduce the combustion air  
and the firing rate will lower to maintain  
the desired outlet temperature. When  
the requirement is fully satisfied, the  
heating contacts are opened, de-  
energizing the heat.The specific  
sequence of operation of the gas heat  
will depend on the size of the heat

compressors will be staged up as  
necessary. Minimum on/off timing of  
compressors prevents rapid cycling.  
On units with economizer, a call for  
cooling will modulate the fresh air  
dampers open.The rate of economizer  
modulation is based on deviation of the  
zone temperature from setpoint, i.e., the  
further away from setpoint, the faster the  
fresh air damper will open. First stage of  
cooling will be allowed to start after the  
economizer reaches full open.  
As additional heat is required, the UCM  
will close the second stage heating  
contacts and depending on heat module  
size, will open either the second stage of  
the gas valve, or a second stage gas  
valve.  
Note that the economizer is only allowed  
to function freely if one of the following  
conditions is met: For dry bulb  
economizer control, the ambient  
temperature must be below the dry bulb  
temperature control setting. For  
reference enthalpy economizer control,  
outdoor air enthalpy must be below the  
enthalpy control setting. For comparative  
enthalpy economizer control, outdoor air  
enthalpy must be below the enthalpy of  
the return air.  
During heating operation, an electronic  
flame safety control provides continuous  
flame supervision. If combustion should  
become unstable for any reason, heating  
will automatically shut down. After one  
minute, another 60 second pre-purge  
and ignition cycle begins.  
As the heating requirement is satisfied,  
the UCM will open the second stage  
heating relay, de-energizing the second  
stage of heat. When the requirement is  
fully satisfied, the first stage contacts are  
opened, de-energizing the first stage of  
heat.The specific sequence of operation  
of the gas heat will depend on the size of  
the heat exchanger.  
At outdoor air temperatures above the  
enthalpy control setting, mechanical  
cooling only is used and the outdoor air  
dampers remain at minimum position.  
If the unit does not include an  
economizer, mechanical cooling only is  
used to satisfy cooling requirements.  
Outdoor air dampers may be set  
manually for a maximum of 25 percent

supply air temperature drops to 10 F  
below the Occupied zone heating  
temperature setpoint, one stage of heat  
will be brought on to maintain a  
minimum supply air temperature.The  
heat stage is dropped if the supply air  
temperature rises to 10 F above the  
Occupied zone heating temperature  
setpoint.  
If ignition is not proven, the ignition  
transformer is de-energized. After a time

As the heating requirement is satisfied,  
the UCM will reduce the combustion air,  
and the firing rate will lower to maintain  
the desired outlet temperature. When  
the requirement is fully satisfied, the  
heating contacts are opened, de-  
energizing the heat.The specific

Electric Heating  
The three stages of electric heat will be  
sequenced on the zone demand signal  
from the zone sensor.The signal is sent  
to the UCM and the stages are

Control Sequences of  
Operation Common to Both  
VAV and CV Units  
1
Space Pressure Control — Statitrac™  
Note:When using the Morning Warmup  
option in a VAV heating/cooling rooftop,  
airflow must be maintained through the  
rooftop unit.This can be accomplished  
by electrically tying the VAV boxes to the  
unoccupied output relay contacts on the  
Rooftop Module (RTM) or by using  
changeover thermostats. Either of these  
methods will assure adequate airflow  
through the unit and satisfactory heating  
of the building.  
A pressure transducer is used to  
measure and report direct space  
(building) static pressure.The user-  
defined control parameters used in this  
control scheme are space static pressure  
setpoint and deadband. As  
the economizer opens, the building  
pressure rises and enables the  
exhaust fan and dampers or exhaust  
VFD.The exhaust dampers or VFD then  
modulate to maintain space pressure  
within the deadband.

Ventilation Override (VOM)  
2
The user can customize up to five (5)  
different override sequences for  
Morning Warm-up  
purposes of ventilation override control.  
If more than one VOM sequence is being  
requested, the sequence with the highest  
priority is initiated first. Priority schedule  
is that sequence “A” (unit off) is first, with  
sequence “E” (purge with duct pressure  
control) last.  
This feature is available on all types of  
factory-installed heat units and on units  
with no heat, this function may still be  
selected to support systems with heat  
sources not provided by the rooftop unit.  
At the conclusion of Unoccupied mode,  
while the economizer (if supplied) is kept  
closed, the selected zone is heated to the  
user-defined Morning Warm-up setpoint.  
The unit is then released to Occupied  
mode.There are two types of Morning  
Warm-up: full capacity or cycling

then reselect the RDE value to equal the  
MOP value.  
Select a fuse rating equal to the RDE  
value. If the RDE value does not equal a  
standard fuse size as listed in NEC 240-6,  
select the next higher standard fuse  
rating. NOTE: If the selected RDE is  
greater than the selected MOP value,  
then reselect the RDE value to equal the  
MOP value.  
Electrical Service Sizing  
To correctly size electrical service  
wiring for your unit, find the  
Set 2. Rooftop units with Electric Heat  
appropriate calculations listed below.  
Each type of unit has its own set of  
calculations for MCA (Minimum Circuit  
Ampacity), MOP (Maximum  
Overcurrent Protection), and RDE  
(Recommended Dual Element fuse  
size). Read the load definitions that  
follow and then find the appropriate  
set of calculations based on your unit  
type.  
a. Single Source Power (380V, 415V, 460V,  
and 575V)  
To arrive at the correct MCA, MOP, and  
RDE values for these units, you must  
perform two sets of calculations. First  
calculate the MCA, MOP, and RDE values  
as if the unit was in cooling mode (use  
the equations given in Set 1).Then  
calculate the MCA, MOP, and RDE values  
as if the unit were in the heating mode as  
follows.  
b. Dual Source Power units (200V and  
230V)  
These units will have two circuit values  
shown on the nameplate.The first circuit  
value will be the refrigeration (cooling  
mode) values calculated per Set 1.The  
second set of circuit values shown on the  
nameplate will be for the electric heating  
circuit as follows.  
Set 1 is for cooling only and cooling  
with gas heat units, and set 2 is for  
cooling with electric heat units.  
(Keep in mind when determining LOADS  
that the compressors don’t run while the  
unit is in the heating mode).  
Load Definitions: (To determine load  
values, see the Electrical Service Sizing  
DataTables on the following page.)  
MCA = (1.25 x LOAD3)  
MOP = (1.25 x LOAD3)  
For units using heaters less than 50 kw.  
Select a fuse rating for the electric  
heating circuit that’s equal to the MOP  
value obtained in the equation above. If  
the MOP value does not equal a  
standard fuse size as listed in NEC 240-6,  
select the next lower standard fuse rating  
(see note below for exception).  
MCA = 1.25 x (LOAD1 + LOAD2 + LOAD4)  
+ (1.25 x LOAD3)  
LOAD1 = CURRENT OFTHE LARGEST  
MOTOR (COMPRESSOR OR FAN  
MOTOR)  
For units using heaters equal to or  
greater than 50 kw.  
LOAD2 = SUM OFTHE CURRENTS OF  
ALL REMAINING MOTORS  
MCA = 1.25 x (LOAD1 + LOAD2 + LOAD4)  
+ LOAD3  
LOAD3 = CURRENT OF ELECTRIC  
HEATERS  
The nameplate MCA value will be the  
larger of the cooling mode MCA value or  
the heating mode MCA value calculated  
above.  
NOTE: If selected MOP is less than the  
MCA obtained in the equation above,  
then reselect the lowest standard  
maximum fuse size which is equal to or  
larger than the MCA, provided the  
reselected fuse size does not exceed 800  
amps.  
LOAD4 = ANY OTHER LOAD RATED AT  
1 AMP OR MORE  
Set 1. Cooling Only Rooftop Units and  
Cooling with Gas Heat Rooftop Units  
MOP = (2.25 x LOAD1) + LOAD2 + LOAD3  
+ LOAD4  
MCA = (1.25 x LOAD1) + LOAD2 +  
LOAD4  
The selection MOP value will be the  
larger of the cooling mode MOP value or  
the heating mode MOP value calculated  
above.  
RDE = LOAD3  
MOP = (2.25 x LOAD1) + LOAD2 +  
LOAD4  
Select a fuse rating for the electric  
heating circuit that’s equal to the RDE  
value. If the RDE value does not equal a  
standard fuse size as listed in NEC 240-6,  
select the next higher standard fuse  
rating. NOTE: If the selected RDE is  
greater than the selected MOP value,  
then reselect the RDE value to equal the  
MOP value.  
Select a fuse rating equal to the MOP  
value. If the MOP value does not equal  
a standard fuse size as listed in NEC  
240-6, select the next lower standard  
fuse rating. NOTE: If selected MOP is  
less than the MCA, then reselect the  
lowest standard maximum fuse size  
which is equal to or larger than the  
MCA, provided the reselected fuse size  
does not exceed 800 amps.  
Select a fuse rating equal to the MOP  
value. If the MOP value does not equal a  
standard fuse size as listed in NEC 240-6,  
select the next lower standard fuse  
rating. NOTE: If selected MOP is less than  
the MCA, then reselect the lowest  
standard maximum fuse size which is  
equal to or larger than the MCA,  
GENERAL NOTES:  
provided the reselected fuse size does  
not exceed 800 amps.  
On 20 to 130 ton rooftops, the selected  
MOP value is stamped in the MOP field  
RDE = (1.5 x LOAD1) + LOAD2 + LOAD3 + on the nameplate.  
LOAD4  
RDE = (1.5 x LOAD1) + LOAD2 + LOAD4  
Select a fuse rating equal to the RDE  
value. If the RDE value does not equal  
a standard fuse size as listed in NEC  
240-6, select the next higher standard  
fuse rating. NOTE: If the selected RDE  
is greater than the selected MOP value,  
The selection RDE value will be the larger  
of the cooling mode RDE value or the  
heating mode RDE value calculated  
above.

economizer has three optional  
economizer controls available:  
comparative enthalpy, reference  
enthalpy, or dry bulb control.  
modulating exhaust discharge  
dampers are modulated in response to  
building pressure. A differential  
pressure control system, called  
Statitrac™, uses a differential pressure  
transducer to compare indoor building  
pressure to atmospheric pressure.The  
FC exhaust fan is turned on when  
required to lower building static  
pressure to setpoint.The Statitrac  
control system then modulates the  
discharge dampers to control the  
building pressure to within the  
adjustable, specified dead band that is  
set at the Human Interface Panel.
