Features and  
Benefits  
Quality and Reliability are enhanced  
through ReliaTel control and logic:  
ReliaTel MakesTesting Easy  
Easy to Install, Service and  
Maintain  
ReliaTel requires no special tools to run  
theVoyager unit through its paces.  
Simply place a jumper betweenTest 1  
andTest 2 terminals on the LowVoltage  
Terminal Board and the unit will walk  
through its operational steps  
automatically.  
—prevents the unit from short cycling,  
considerably improving  
compressor life.  
Because todays owners are very cost-  
conscious when it comes to service and  
maintenance, theTrane Voyager was  
designed with direct input from service  
contractors.This valuable information  
helped to design a product that would get  
the serviceman off the job quicker and  
save the owner money.Voyager does  
this by offering:  
—ensures that the compressor will run  
for a specific amount of time which  
allows oil to return for better  
lubrication, enhancing the reliability of  
the compressor.  
—The unit automatically returns  
control to the zone sensor after  
stepping through the test mode a  
single time, even if the jumper is  
left on the unit.  
Voyager with ReliaTel reduces the  
number of components required to  
operate the unit, thereby reducing  
possibilities for component failure.  
Quality and Reliability  
ReliaTel™ Controls (LCI-R)  
As long as the unit has power and the  
“system on” LED is lit, ReliaTel is  
operational.The light indicates that the  
controls are functioning properly.  
ReliaTel Makes Installing and  
Servicing Easy  
ReliaTel eliminates the need for field  
installed anti-shortcycle timer and time  
delay relays. ReliaTel controls provide  
these functions as an integral part of the  
unit.The contractor no longer has to  
purchase these controls as options and  
pay to install them.  
ReliaTel features expanded diagnostic  
capabilities when utilized withTrane  
Integrated Comfort™ Systems.  
Some zone sensor options have central  
control panel lights which indicate the  
mode the unit is in and possible  
diagnostic information (dirty filters for  
example).  
The wiring of the low voltage connections  
to the unit and the zone sensors is as  
easy as 1-1, 2-2, and 3-3.This simplified  
system makes wiring easier for the  
installer.  
Other ReliaTel Benefits  
ReliaTel controls provide unit control for  
heating, cooling and ventilating utilizing  
input from sensors that measure outdoor  
and indoor temperature.  
The ReliaTel built-in anti-shortcycle timer,  
time delay relay and minimum “on” time  
control functions are factory tested to  
assure proper operation.  
ReliaTel softens electrical “spikes” by  
staging on fans, compressors and  
heaters.  
Intelligent Fallback is a benefit to the  
building occupant. If a component goes  
astray, the unit will continue to operate at  
predetermined temperature setpoint.  
ReliaTel™  
Intelligent Anticipation is a standard  
ReliaTel feature. It functions continuously  
as ReliaTel and zone sensor(s) work  
together in harmony to provide much  
tighter comfort control than conventional  
electro-mechanical thermostats.  
The same ReliaTel Board fits allVoyager  
Packaged Gas/Electrics, Cooling with  
Electric Heat, and Heat Pump models.  
This provides standardization of parts for  
contractors. Less money is tied up in  
inventory with ReliaTel.

Features and  
Benefits  
Drum andTube Heat Exchanger  
The heat exchanger is manufactured  
using aluminized steel with stainless  
steel components for maximum  
durability.The requirement for cycle  
testing of heat exchangers is 10,000  
cycles by ANSI Z21.47.This is the  
standard required by both UL and AGA  
for cycle test requirements. American  
Standard requires the design to be  
tested to 2½ times this current  
standard.The drum and tube design has  
been tested and passed over 150,000  
cycles, which is over 15 times the  
current ANSI cycling requirements.  
The negative pressure gas valve will  
not allow gas flow unless the  
combustion blower is operating.This is  
one of our unique safety features.  
The forced combustion blower supplies  
pre-mixed fuel through a single  
stainless steel burner screen into a  
sealed drum where ignition takes place.  
It is more reliable to operate and  
maintain than a multiple burner system.  
The hot surface ignitor is a gas ignition  
device which doubles as a safety device  
utilizing a continuous test to prove the  
flame.The design is cycle tested at the  
factory for quality and reliability.  
Our gas/electric rooftops exceed all  
California seasonal efficiency  
requirements and perform even better  
than the California NOx emission  
requirements.

Procedures  
To determine the total unit static pressure  
add the external static pressure to the  
additional static created by the added  
features:  
Cooling Capacity  
Heating Capacity  
Step 1 — Calculate the building heating  
load using theTrane calculation form or  
other standard accepted method.  
Step 1 — Calculate the buildings total  
and sensible cooling loads at design  
conditions. Use theTrane calculation form  
or any other standard accepted method.  
External Static (duct system) 0.45 wg  
Step 2 — Size the system heating  
capacity to match the calculated building  
heating load.The following are building  
heating requirements:  
a. Total heating load of 165 MBh  
b. 8000 cfm  
c. Fuel - Natural gas  
Standard Filter 2 in. (fromTable PD-36)  
0.11 g  
Example:The following are the building  
requirements:  
a. Electrical Characteristics: 460/60/3  
b. Summer Design Conditions: Entering  
Evaporator Coil: 80° DB/ 67°WB  
Outdoor Ambient: 95° DB  
Economizer (100% Return Air fromTable  
PD-20) 0.05 wg

c. Total Cooling Load: 220 MBh  
d. Sensible Cooling Load: 140 MBh  
e. Airflow: 8000 cfm External Static  
Pressure: 0.450 in wg  
f. downflow configuration  
g. economizer  
Note:The Evaporator Fan Performance  
Table PD-20 has already accounted for  
the pressure drop for standard filters and  
wet coils (see note belowTable PD-20).  
Therefore the actual total static pressure  
is 0.61-0.11 = 0.50 wg.  
For theYC*240B3, there are two heating  
capacities available, 250 MBh and 400  
MBh input models shown inTable PD-35.  
The output capacities of these furnaces  
are 175 MBh and 300 MBh respectively.  
The low heat model with 175 MBh best  
matches the building requirements,  
indicating aYC*240B3 should be  
selected.  
Step 2 — As a starting point, a rough  
determination must be made of the size  
of the unit. The final selection will be  
made after examining the performance  
at the given conditions. Divide the total  
cooling load by the nominal BTUH per ton  
(12 MBh per ton); then round up to the  
nearest unit size.  
With 8000 cfm and 0.50 inches external  
static pressure. Table PD-20 shows 3.96  
bhp for this model. At these conditions,  
the note below the table gives a formula  
to calculate Fan Motor Heat:  
Air Delivery Selection  
External static pressure drop through the  
air distribution system has been  
calculated to be 0.50 inches of water.  
EnterTable PD-20 for aYC*240B3 at 8000  
cfm and 0.50 static pressure.The  
standard motor at high speed will give  
the desired airflow.  
3.15 X bhp = MBh  
3.15 X 3.96 = 12.47 MBh.  
220 MBh / 12 MBh = 18.333 (approx 20  
tons).  
Subtracting the fan motor heat from the  
gross cooling capacity of the unit:  
NetTotal Cooling Capacity =  
246 MBh - 12.47 = 251.53 MBh  
Net Sensible Cooling Capacity =  
176 MBh - 12.47 = 163.53 MBh.  
Step 3 — Examine gross capacity:Table  
PD-4 shows that aYC*240B3 has a gross  
cooling capacity of 246 MBh and 176  
MBh sensible capacity at 95 DB ambient  
and 8000 cfm with 80 DB/ 67WB air  
entering the evaporator.  
Accessory Selection  
Select accessories needed to  
accommodate the application.  
Since the NetTotal Cooling Capacity  
meets the cooling load requirements of  
220 MBh, we are satisfied with this  
selection.  
To Find Capacity at Intermiediate  
Conditions Not in theTable  
When the design conditions are between  
two numbers that are in the capacity  
table, interpolation is required to  
approximate the capacity.  
Note: Extrapolation outside of the table  
conditions is not recommended.  
Step 4Verify the unit will have enough  
capacity to meet the building  
requirements by determining the net  
capacity, which includes heat generated  
by the fan. In order to select the correct  
unit, the fan motor heat must be  
deducted from the gross coolingcapacity.  
The amount of heat that the fan motor  
generates is dependent on the effort by  
the motor - cfm and static pressure.

additional .04 for the mandatory 2”  
pleated filters required when ordering the  
dehumidification option.Total static  
pressure =  
1.0+0.035+0.04=1.075  
(1.1 for manual calculations)  
Do not forget to also add any additional  
static from other accessories.  
• Energize compressor or both  
compressors (2 stage compressor units).  
• Hot gas reheat valve is energized and  
hot gas is diverted to the reheat coil.  
• Dehumidification/reheat is terminated  
when space humidity is reduced to 5%  
below relative humidity setpoint.

At MA, air enters the RTU.The RTU filters,  
cools, and dehumidifies the air as it  
moves through the evaporator coil. Air  
leaves the evaporator coil saturated at  
the preset dew point condition (SA) and  
is reheated by the hot gas reheat coil to  
deliver 71°F (SA) supply air to the space.  
Step 4: Determine reheat  
temperature rise  
Using the leaving evaporator temp (SA),  
go to PD-37 and determine the reheat  
temperature rise for that particular cfm:  
17.55°F db  
Table PD-29 (airflow table for 20 ton  
dehumidification units) indicates that a  
standard motor and drive is needed for  
this airflow and static pressure range.  
Note: Reheat temperature rise is based  
on supply airflow and leaving  
evaporator coil temperature.
