Other manufacturers utilize a fan
tracking control scheme whereby the
return fan speed tracks the supply fan
speed in a linear fashion. This
scheme works well at minimum and
maximum CFM airflow. However,
due to the dissimilar performance
characteristics of the supply and
return fan, building pressure is
difficult to control at points between
minimum and maximum CFM
airflow.
Trane Statitrac™ control is a highly
accurate and efficient method of
maintaining building pressure

installation.
Building space pressurization control
is achieved with a 100 percent
modulating exhaust system that
features a single forward curved fan,
with modulating discharge dampers
that operates only when needed or a
100% modulating plenum return fan
with airfoil wheel that operates
continuously with the supply fan.
Most of the operating hours of the
100 percent modulating exhaust
system are at part load, resulting in
energy savings.
The unit mounted Human Interface
and the Remote Human Interface
Panels' functions are identical, with
the exception of the Service mode
which is not available on the Remote
Human Interface Panel. This common
interface feature requires less time
for building maintenance personnel
to learn to interact with the unit.
The Trane return fan/building
pressurization control system
eliminates the effects of dissimilar
supply/return fan characteristics
experienced in a linear tracking
control system by modulating the
exhaust dampers based on space
pressure, the return/economizer
dampers based on ventilation
requirements, and the return fan
speed based on return plenum static
pressure. The supply fan, return fan,
exhaust damper, and return/
economizer damper systems act
independently from one another to
maintain comfort and building
pressure.
All air handler control parameters are
adjustable and can be setup through
the Remote Human Interface Panel
such as, but not limited to: system
on/off, 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 keypad.
Statitrac, with the 100 percent
modulating exhaust system,
provides comfort and economy for
buildings with large air handler
systems. Statitrac, with the 100%

Up to 56 different air handler
diagnostic points can be monitored

pressure, and applications requiring

The return fan operates whenever
the supply fan is in operation. The
unit exhaust dampers are modulated

The unit economizer and return air
dampers are modulated based on
ventilation control, minimum outside

return fan speed is modulated based
on a return duct static pressure
deadband control. Using the unit

Features and Benefits
Supply Fans with Inlet Guide
Vanes
Trane airfoil fans 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 result
in superior part load performance.
Variable Frequency Drives
(VFD)
Variable Frequency Drives are factory
installed and tested to provide
supply/exhaust/return fan motor
speed modulation. VFD's, as
compared to inlet guide vanes or
discharge dampers, are quieter, more
efficient, and may be 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.

Control
Cooling/Economizer
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.
During Occupied cooling mode of
operation, the economizer (if
available) and cooling are used to
control the supply air temperature.
The supply air temperature setpoint
and deadband are user-defined at
the Human Interface Panel.
Inlet Guide Vanes Control
Inlet guide vanes are driven by a
modulating 0-10 vdc signal from the
Rooftop Module (RTM). A pressure
transducer measures duct static
pressure, and the inlet guide vanes
are modulated to maintain the
supply air static pressure within an
adjustable user-defined range.
The supply air temperature setpoint
may be user-defined from the BAS/
Network. If the conditions 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 hydronic valve will be modulated
to maintain supply air temperature
setpoint.
The range is determined by the
supply air pressure setpoint and
supply air pressure deadband, which
are set through the Human Interface
Panel or BAS/Network.
The range is determined by the
supply air pressure setpoint and

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 will reduce
its output frequency to maintain
operation.
Inlet guide vane assemblies installed
on the supply fan inlets regulate fan

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 primary cooling, thus
savings in mechanical cooling kw,
but an increase in supply fan kw may
occur.
Modulating Gas
Upon a call for heating, the HEAT
module closes the heating contacts,
beginning the firing sequence. First,
the heat exchanger combustion
blower begins operation. Upon
positive proving of combustion
airflow, a 60 second pre-purge cycle
is executed. Then the ignition
sequence takes place.
Electric Heating
The individual stages of electric heat
will be sequenced on the zone
demand. The number of available
stages will depend on the unit size
and heat capacity selected.
Outdoor air heating reset is the
inverse of cooling, with the same
principles applied.
If ignition is not proven, the safety
control locks out and must be
manually reset. As long as there is a
call for heat, the safety control can be
reset, which starts another purge

Comparative Enthalpy Control
of Economizer
An optional Comparative Enthalpy
system is used to control the
operation of the economizer, and
measures the temperature and
humidity of both return air and
outside air to determine which
source has lower enthalpy. This
system allows true comparison of
outdoor air and return air enthalpy
by measurement of outdoor air and
return air temperatures and
humidities.

Ventilation (DCV)
A ventilation reset function that
provides the necessary ventilation for
occupants and reduces energy
consumption by minimizing the
outdoor air damper position (or the
OA flow setpoint with TRAQs) below
the Building Design Minimum, while
still meeting the ASHRAE Std 62.1-
2004 ventilation requirements.
When using the night setback options
with a VAV heating/cooling air
handler, airflow must be maintained
through the air handler unit. This can
be accomplished by electrically tying
the VAV boxes to the VAV Box 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 temperature
control of the building.

systems.
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 under-pressurization of the
building.
100 Percent Modulating Exhaust
with Statitrac Control, Constant
Volume and VAV Units
In a return fan system, the return fan
is in series with the supply fan, and
operates continuously whenever the
supply fan is operating to maintain
return air volume. The supply fan
motor and drives are sized to deliver
the design CFM based on internal
and discharge static pressure losses
only.
For both CV and VAV air handlers,
the 100 percent modulating exhaust
discharge dampers (or VFD) are
modulated in response to building
pressure. A differential pressure
control system, Statitrac, uses a
differential pressure transducer to
compare indoor building pressure to
atmospheric pressure.
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.
The return fan motor and drives are
sized to pull the return CFM back to
the unit based on return duct static.
Therefore, with a return fan system,
the supply fan ordinarily requires
less horsepower than a system with
an exhaust fan
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
(or VFD) to control the building
pressure to within the adjustable,
specified deadband that is set at the
Human Interface Panel.
The reason for applying either a
return, or exhaust fan is to control
building pressure. The Trane 100
percent modulating exhaust system
with Statitrac is an excellent choice
for controlling building pressure in
the majority of applications.

Trane's 100 percent modulating

return or exhaust fan systems with
Statitrac may be used on any air
handler application that has an
outdoor air economizer.

are modulated independent of the

Applications Considerations
When using an IntelliPak II Air
Handler for horizontal supply and/or
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 air handler size, but a range of
0.10 inches to 0.30 inches can be
expected. The openings on the air
handler all have a one inch lip around
the perimeter to facilitate ductwork
attachment.
Trane can provide five (5) different
ventilation override sequences on
both CV and VAV IntelliPak II Air

Ventilation Override
Sequences
Several basic guidelines for unit
placement should be followed to
minimize sound transmission
through the building structure:
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 air
handler 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 air handling system.
1
Locate the unit's center of gravity
close to or over a column or main
support beam to minimize roof
deflection and vibratory noise.
2
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.
If the roof structure is very light, roof
joists should be replaced by a
structural shape in the critical areas
described above.

several duct diameters to allow the
conversion of fan energy from
velocity pressure to static pressure.
However, when job conditions
dictate elbows be installed near the
air handler 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
air handler outlet should be directed
at the outside radius of the elbow
rather than the inside as illustrated in

Selection Procedure
an air density correction is needed to
project accurate unit performance.
In order to better illustrate this
procedure, the following example is
used:
Exhaust Fan Motor Sizing
The exhaust/return fan is selected
based on total return system
negative static pressure and exhaust
fan CFM. Return system negative
static includes return duct static, and
any other job site applicable static
pressure drop.
Figure 18, p. 37 shows the air density
ratio at various temperatures and
elevations.
Consider an air handler"C" that is to
deliver 32000 actual CFM at 3-inches
total static pressure (tsp), 55°F
leaving air temperature, at an
elevation of 5000 ft.
The procedure to use when selecting
a supply or exhaust/return fan at
elevations and
density ratio is 0.86.
Return duct static pressure = 0.30
inches.
temperatures other than standard is
as follows:
2. Tsp = 3.0-inches / 0.86 = 3.49
inches tsp.
Total return system negative static
pressure = 0.30 inches.
1. First, determine the air density
p. 48 air handler"C" (without inlet
vanes) will deliver 32000 CFM at
3.49 inches TSP at 997 RPM and
30.27 BHP.
Exhaust fan CFM = 36000 CFM
2. Divide the static pressure at the
nonstandard condition by the air
density ratio to obtain the
BHP is 21.44 BHP at 400 RPM. Thus,
the exhaust fan motor selected is 25
HP.

3. Use the actual CFM and the

curves.

calculated at standard and then
converted to actual using the
these factors to the capacities
selected at standard CFM so as to
correct for the reduced mass flow
rate across the condenser.
The same static pressure and CFM
considerations must be taken for
return fan size, horsepower, and
drive selection as are required for
exhaust fan sizing. However, since
the return fan runs continuously the
sensible heat generated by the return
fan motor must be included in the
entering evaporator coil mixed air
temperature equation.
5. BHP must be multiplied by the
air density ratio to obtain the
actual operating BHP.
Heat selections other than gas heat
will not be affected by altitude.
Nominal gas capacity (output) should
be multiplied by the factors given in
heating supply air temperature.
In this selection, if the return motor

1. Supply fan performance table includes internal resistance of air handler. For total
static pressure determination, system external static pressure must be added to
appropriate component sp drops (chilled water coil, filters, optional economizer,
optional heating system).
2. Maximum SP leaving the air handler is 5.5" H20 positive.

Notes:
1. Supply fan performance table includes internal resistance of air handler. For total static pressure determination, system external
static pressure must be added to appropriate component sp drops (chilled water coil, filters, optional economizer, optional
heating system).
2. Maximum SP leaving the air handler is 5.5" H20 positive.

Notes:
1. Supply fan performance table includes internal resistance of air handler. For total static pressure determination, system external
static pressure must be added to appropriate component sp drops (chilled water coil, filters, optional economizer, optional
heating system).
2. Maximum SP leaving the air handler is 5.5" H20 positive.

Notes:
1. Supply fan performance table includes internal resistance of air handler. For total static pressure determination, system external
static pressure must be added to appropriate component sp drops (chilled water coil, filters, optional economizer, optional
heating system).
2. Maximum SP leaving the air handler is 5.5" H20 positive.

Electrical Service Sizing
To correctly size electrical service
wiring for a unit, find the appropriate
calculations listed below. Each type
of unit has its own set of calculations
for MCA (Minimum Circuit
Note: If the selected RDE is greater
than the selected MOP value,
then select the RDE value to
equal the MOP value.
Note: If the selected RDE is greater
than the selected MOP value,
then select the RDE value to
equal the MOP value.
Ampacity), MOP (Maximum
GENERAL NOTE
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 unit
type.
Set 2. Cooling with Electric Heat
Note: The selected MOP value is
stamped in the MOP field on
the nameplate.
To arrive at the correct MCA, MOP,
and RDE values for these units, two
sets of calculations must be
performed. 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.
Note: Set 1 is for cooling only and
cooling with gas heat units,
and set 2 is for cooling with
electric heat units.
Load Definitions: (To determine load
values, see the Electrical Service
Sizing Data Tables on the following
page.)
MCA = 1.25 x (LOAD1 + LOAD2 +
LOAD4) + LOAD3
LOAD1 = CURRENT OF THE
LARGEST MOTOR
The nameplate MCA value will be
the larger of the cooling mode MCA
value or the heating mode MCA
value calculated above.
LOAD2 = SUM OF THE CURRENTS
OF ALL REMAINING MOTORS
MOP = (2.25 x LOAD1) + LOAD2 +
LOAD3 + LOAD4
LOAD3 = CURRENT OF ELECTRIC
HEATERS
The selection MOP value will be the
larger of the cooling mode MOP
value or the heating mode MOP
value calculated above.
LOAD4 = ANY OTHER LOAD RATED
AT 1 AMP OR MORE
Set 1. Cooling with Gas Heat Air
Handling Units
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.
MCA = (1.25 x LOAD1) + LOAD2 +
LOAD4
MOP = (2.25 x LOAD1) + LOAD2 +
LOAD4
Note: If selected MOP is less than
the MCA, then select the
lowest standard maximum
fuse size which is equal to or
larger than the MCA,
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.
provided the selected fuse
size does not exceed 800
amps.
Note: If selected MOP is less than
the MCA, then select the
lowest standard maximum
fuse size which is equal to or
larger than the MCA,
RDE = (1.5 x LOAD1) + LOAD2 +
