Comfort Control

Statitrac™ Direct Space
Building Pressurization Control

Variable Frequency Drives
(VFD)

Trane’s Statitrac™ control is a highly
accurate and efficient method of
maintaining building pressure control
with a large rooftop air conditioner.

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

The efficiency is achieved with a 100
percent modulating exhaust system with
two forward-curved fans with
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.

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.

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.
The unit mounted Human Interface and
the Remote Human Interface Panels’
functions are identical, except for the
Service mode 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. All of the
rooftop’s control parameters are
adjustable and can be set up 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
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.

RT-PRC010-EN

Statitrac control is simple! The space
pressure control turns the exhaust fans
on and off as required and modulates
exhaust dampers to maintain space
pressure within the space pressure dead
band. Using the unit mounted Human
Interface Panel you can
1) adjust space pressure setpoint
2) adjust space pressure dead band
3) measure and read building space
pressure. The modulating exhaust
system maintains the desired building
pressure, saving energy while keeping
the building at the right pressure. Proper
building pressurization eliminates
annoying door whistling, doors standing
open, and odors from other zones.
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.

Trane 3-D® Scroll Compressor
Simple Design with 70% Fewer Parts
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.

With over twenty years of development
and testing,Trane 3-D Scroll
compressors have undergone more

than 400,000 hours of laboratory testing
and field operation.This work combined
with over 25 patents makesTrane the
worldwide leader in air conditioning
scroll compressor technology.

One of two matched scroll plates — the
distinguishing feature of the scroll
compressor.

Chart illustrates low torque variation of
3-D Scroll compressor vs reciprocating
compressor.

Proven DesignThrough Testing and
Research

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.

Considerations

EXHAUST AIR OPTIONS

Application Recommendations

d

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.

1
100 percent modulating exhaust with
Statitrac™ control

Because discharge dampers modulate
the airflow, the exhaust fan may be
running unloaded whenever the
economizer dampers are less than 100
percent open.

A building may have all or part of its
exhaust system in the rooftop unit. Often,
a building provides exhaust external to
the air conditioning equipment.This
external exhaust must be considered
when selecting the rooftop exhaust
system.
IntelliPak® Rooftop units offer four types
of exhaust systems:
1

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
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 (or VFD) to control the building
pressure to within the adjustable,
specified dead band that is set at the
Human Interface Panel.
Advantages of the Statitrac™
100 percent modulating exhaust
system are:

The exhaust fan runs only when needed
to lower building static pressure.
b

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.
The reason for either a return air fan or
an exhaust fan is to control building
pressure.TheTrane 100 percent
modulating exhaust system with
Statitrac does a better job controlling
building pressure than return fans simply
because 100 percent modulating exhaust
discharge dampers (or VFD) are
controlled directly from building
pressure, rather than from an indirect
indicator of building pressure such as
outdoor air damper position.
The 100 percent modulating exhaust
system with Statitrac may be used on
any rooftop application that has an
outdoor air economizer. However, when
most exhaust is handled external to the
rooftop or when building pressure is not
critical, one of the other less expensive
methods of exhaust may be used.

9

Application
Considerations

2
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
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.
The IntelliPak® Rooftop unit offers
modulating 100 percent exhaust system.
This fan system has performance
capabilities equal to the supply fan.The
FC exhaust fans are started by the

economizer’s outdoor air damper
position and the exhaust dampers track
the economizer outdoor air damper
position.The amount of air exhausted by
this fan is controlled by modulating
discharge dampers at the fan outlet.The
discharge damper position is controlled
by a signal that varies with the position
of the economizer dampers. When the
exhaust fans start, the modulating
discharge dampers are fully closed, and
exhaust airflow is 15 to 20 percent of
total exhaust capabilities.
3
50 Percent Exhaust System
The 50 percent exhaust system is a
single FC exhaust fan with half the airmoving 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 50 percent exhaust system generally
should not be selected for more than 40
to 50 percent of design supply airflow.
Since it is an on/off nonmodulating

system, it does not vary exhaust CFM
with the amount of outside air entering
the building.Therefore, if selected for
more than 40 to 50 percent of supply
airflow, the building may become underpressurized 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
sized for more than 50 percent of design
supply airflow.
4
Barometric Relief Dampers
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
requirements less than 25 percent.

Application
Considerations

Horizontal Discharge
The typical rooftop installation has both
the supply and return air paths routed
through the roof curb and building roof.
However, many rooftop installations
require horizontal supply and/or return
from the rooftop because of a building’s
unique design or for acoustic
considerations.
Trane has two ways to accomplish
horizontal supply and/or return.The first
applies to all IntelliPak® Rooftop units.
Special field supplied curbs are installed
that use the unit’s standard discharge
and return openings.The supply and
return air is routed through the curb to
horizontal openings on the sides of the
curb.The second method available for
horizontal supply and return applies to

20 - 75 tons SXHF, SFHF, SLHF, SSHF, and
90 - 130 tons SXHG, SLHG and SSHG
design units ONLY. With this method the
standard discharge and return openings
are blocked in the field. Access panels
are removed as indicated in Figures AC-1
and AC-2.These openings are used for
the discharge and return. No special
curb is needed.
SXHF, SFHF, SLHF, SSHF Units
Figure AC-1 is a simplified sketch of the
rooftop showing which panels can be
used for horizontal supply and/or return.
To supply air horizontally, the panels that
normally house the heat accessory
controls (Panel A) and the gas heat
barometric dampers (Panel B) can be
removed and either of the openings

Figure AC-2 Horizontal Discharge Panel Dimensions — 20 - 75 Tons SXHF, SFHF, SLHF, SSHF Units

used as a unit discharge (see note 1). To
return air horizontally, the exhaust fan
access door (Panel C) can be removed
and used as a return opening. Tables AC1, 2 and 3 show dimensions for those
panels.
Horizontal Discharge on SXHF, SFHF,
SLHF and SSHF Rooftops (20 to 75 tons)
The SXHF (extended casing cooling
only), SFHF (gas heat), SSHF (steam
heat) and SLHF (hot water heat) rooftops
can be field modified to supply and
return air horizontally without the use of
a horizontal supply/return curb.
To supply air horizontally on SXHF only,
the panels that normally house the heat
accessory controls (Panel A) and the gas
heat barometric dampers (Panel B) can
be removed and either of the openings
used as a unit discharge. To return air
horizontally, the exhaust fan access door
(Panel C) can be removed and used as a
return opening.
1. For horizontal discharge on SFHF, SLHF and SSHF
units, only the Panel B can be removed. Panel A
cannot be used due to the location of the heating
coils.
2. For horizontal discharge on SFHF (gas heat) models,
the block off under the heater must be removed.
After removal, a support must be added for the drain
tube.
3. Supply and Return Base openings must be covered
when converting to a horizontal configuration.

Note: Cannot remove Panel A
for horizontal discharge on
SFHF, SLHF, SSHF Units.

Application
Considerations

Figure AC-3 is a simplified sketch
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

because of the location of the heating
coil. Horizontal return is accomplished in
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.
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

perimeter to facilitate ductwork
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.
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 - 130 Tonss 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:
1. SXHG units have two Panel A’s that can be removed. Once unit is installed, panel(s) and the 61 /2 ” vertical
support channel in between may be removed.

Application
Considerations

High Capacity Evaporator Coil
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.
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
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.
Low Ambient Operation — Human
Interface Recommendations
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.
Corrosive Atmospheres
Trane’s IntelliPak® Rooftops are
designed and built to industrial
standards and will perform to those
standards for an extended period

RT-PRC010-EN

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.
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
coatings or copper fins on the condenser
and/or evaporator coils are available on
Trane’s IntelliPak Rooftops.
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.
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.
Trane can provide five (5) different
ventilation override sequences on both

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.
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
• Variable Frequency Drives — on (60
Hz)/off (0 Hz)/controlling
• Exhaust Fan — on/off
• Exhaust Dampers — open/closed
• Economizer dampers — open/closed
• Heat — off/controlling (output for) VAV
Boxes — open/controlling
Compressors and condenser fans are
shut down for any Ventilation 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.
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

13

Application
Considerations

exchanger, leading to premature failure.
For increased reliability, the
recommendation in these applications is
full modulation gas heat. For airflow
limitations and temperature rise across
the heat exchanger information, see
Table PD-24, 25 and RT-EB-104.
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.
Several basic guidelines for unit
placement should be followed to
minimize sound transmission through
the building structure:
1
Never cantilever the condensing section
of the unit. A structural cross member
must support this end of the unit.
2
Locate the unit’s center of gravity close
to or over a column or main support
beam to minimize roof deflection and
vibratory noise.

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.
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.
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.
This program quantifies the airborne
sound generation that can be expected
in each terminal so that the designer can
identify potential sound problems and
make design alterations before
equipment installation.

If the roof structure is very light, roof
joists should be replaced by a structural
shape in the critical areas described
above.

TheTrane Acoustics Program (TAP)
allows modeling of rooftop installation
parameters.The output of this program
shows the resulting indoor NC level for
the modeled installation.This program is
available fromTrane’s Customer Direct
Service Network™ (C.D.S.), ask your
localTrane representative for additional
information on this program.

Clearance Requirements

If several units are to be placed on one
span, they should be staggered to
reduce deflection over that span.

The recommended clearances identified
with unit dimensions should be

3

14

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?
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:
1
To reduce span deflection if more than
one unit is placed on a single span.
Reducing deflection discourages sound
transmission.
2
To assure proper diffusion of exhaust air
before contact with the outside air intake
of adjacent unit.

Application
Considerations

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.

2

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.

1. 20-40 ton models have only one outdoor air intake.
50 - 75 ton models have two outdoor air intakes.
2. 90-130 ton models have two outdoor air intakes on
the backside of the unit and one small air intake at
the end of the unit.

COOLING CAPACITY SELECTION
Step 1 — Nominal Unit Size Selection
A summation of the peak cooling load
and the outside air ventilation load
shows: 430 MBh + 66.9 MBh = 496.9
MBh required unit capacity. From

16

Table PD-9, a 50 ton unit capacity with
standard capacity evaporator coil at
80 DB/65 WB, 95 F outdoor air
temperature and 17,500 total supply cfm
is 551 MBh total and 422 MBh sensible.
Thus, a nominal 50 ton unit with
standard capacity evaporator coil
is selected.
Step 2 — Evaporator Coil Entering
Conditions
Mixed air dry bulb temperature
determination:
Using the minimum percent of OA (1,750
cfm ÷ 17,500 cfm = 10 percent),
determine the mixture dry bulb to the
evaporator.
RADB + % OA (OADB - RADB) = 80 +

Approximate wet bulb mixture
temperature:
RAWB + % OA (OAWB - RAWB) = 65 +
(0.10) (76 - 65) = 65 + 1.1 = 66.1 F
Step 3 — Determine Supply Fan Motor
Heat Gain
Having selected a nominal 50 ton unit,
the supply fan bhp can be calculated.The
supply fan motor heat gain must be
considered in final determination of unit
capacity.

Required capacity =Total peak load + OA
load + supply air fan motor heat.
Required capacity = 430 + 66.9 +
46.0 = 543 MBh (45.2 tons)
Step 5 — Determine Unit Capacity
FromTable PD-9, unit capacity at 81.5 DB/
66.1 WB entering the evaporator, 17,500
supply air cfm, 95 F outdoor ambient, is
561 MBh (45.8 tons) with 426 MBh
sensible.
Step 6 — Determine Leaving Air

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.

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
number 9 — 900 rpm is selected.
Exhaust Fan Motor Sizing
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.
Return duct static pressure = 0.65 inches
Trane roof curb (Table PD-43) = 0.12
inches

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.
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.
The procedure to use when selecting a
supply or exhaust fan on a rooftop for
elevations and temperatures other than
standard is as follows:
1
First, determine the air density ratio
using Figure PAF-1.
2

Total return system negative static
pressure = 0.77 inches

Divide the static pressure at the
nonstandard condition by the air
density ratio to obtain the corrected
static pressure.

Exhaust fan cfm = 12,000 cfm

3

FromTable 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.
Where altitudes are significantly above
sea level, useTables PAF-2 and PAF-3 and
Figure PAF-1 for applicable correction
factors.

Altitude Corrections

4
The fan rpm is correct as selected.
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

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

1
From Figure PAF-1, the air density ratio is
0.86.
2

Step 1 — Determine Air Temperature
Entering Heating Module

Supply air fan motor heat temperature
rise = 46,000 Btu ÷ (1.085 x 17,500 cfm) =
2.42 F
Air temperature entering heating
module = 63.0 + 2.42 = 65.4 F

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.

Note:
1. Capacities expressed as MBh per initial temperature difference (ITD) between the entering air temperature to
the hot water coil and the entering water temperature. Ethylene glycol or other capacities can be determined
from the Trane heating coil computer program. Capacity and pressure drop of ethylene glycol varies greatly
with temperature and concentration.

Notes:
1. Fan performance for 20 and 25 ton rooftops is identical. However, note maximum motor hp size for each size. Contact your local Trane representative for
information on oversized motors.
2. Shaded areas at table extremes note non-standard Bhp or Rpm selection. Contact your local Trane representative for more information.
3. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static must be added to appropriate
component static pressure drops (evaporator coil, filters, optional economizer, optional exhaust fan, optional heating system, optional cooling only extended
casing, optional roof curb).
4. Maximum Cfm (for UL approval) as follows: 20 Ton — 9,000 Cfm, 25 Ton — 11,000 Cfm
5. Minimum motor horsepower is 3 hp.
6. Maximum motor horsepower as follows: 20 Ton — 15 hp, 25 Ton — 15 hp
7. Maximum 3 hp and 5 hp motor Rpm is 1,100, maximum 7.5 hp to 15 hp motor Rpm is 1655.
8. See RT-EB-104 for further details

Notes:
1. Fan performance for 20 and 25 ton rooftops is identical. However, note maximum motor hp size for each size. Contact your local Trane representative for information on
oversized motors.
2. Shaded areas at table extremes note non-standard Bhp or Rpm selection. Contact your local Trane representative for more information.
3. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static must be added to appropriate component
static pressure drops (evaporator coil, filters, optional economizer, optional exhaust fan, optional heating system, optional cooling only extended casing, optional roof curb).
4. Maximum Cfm (for UL approval) as follows: 20 Ton — 9,000, Cfm 25 Ton — 11,000 Cfm.
5. Minimum motor horsepower is 3 hp.
6. Maximum motor horsepower as follows: 20 Ton — 10 hp, 25 Ton — 15 hp.
7. Maximum 3 hp and 5 hp motor Rpm is 1,100, maximum 7.5 hp to 15 hp motor Rpm is 1655.

Notes:
1. Fan performance for 40, 50, and 55 ton rooftops is
identical. However, note maximum motor hp size for
each size. Contact your local Trane representative for
information on oversized motors.
2. Shaded areas at table extremes note non-standard
Bhp or Rpm selection. Contact your local Trane
representative for more information.
3. Supply fan performance table includes internal
resistance of rooftop. For total static pressure
determination, system external static must be added
to appropriate component static pressure drops
(evaporator coil, filters, optional economizer, optional
exhaust fan, optional heating system, optional
cooling only extended casing, optional roof curb).
4. Maximum Cfm (for UL approval) as follows:
40 Ton — 18,000 Cfm
50 Ton — 22,500 Cfm
55 Ton — 24,000 Cfm
5. Minimum motor horsepower is 7.5 hp.
6. Maximum motor horsepower as follows:
40 Ton — 30 hp
50 Ton — 30 hp
55 Ton — 30 hp
7. Maximum 7.5 hp to 15 hp motor Rpm is 1,141 Rpm,
maximum 20 hp to 30 hp motor Rpm is 1,170 Rpm.
8. See RT-EB-104 for further details.

Notes:
1. Fan performance for 40, 50, and 55 ton rooftops is
identical. However, note maximum motor hp size for
each size. Contact your local Trane representative for
information on non-standard motors.
2. Shaded areas at table extremes note non-standard
Bhp or Rpm selection. Contact your local Trane
representative for more information.
3. Supply fan performance table includes internal
resistance of rooftop. For total static pressure
determination, system external static must be added
to appropriate component static pressure drops
(evaporator coil, filters, optional economizer,
optional exhaust fan, optional heating system,
optional cooling only extended casing, optional roof
curb).
4. Maximum Cfm (for UL approval) as follows: 40 Ton
— 18,000 Cfm, 50 Ton — 22,500 Cfm, 55 Ton —
24,000 Cfm
5. Minimum motor horsepower is 7.5 hp.
6. Maximum motor horsepower as follows: 40 Ton —
30 hp, 50 Ton — 30 hp, 55 Ton — 30 hp
7. Maximum 7.5 hp through 15 hp motor Rpm is 1,141
Rpm, maximum 20 hp through 30 hp motor Rpm is
1,170 Rpm.
8. See RT-EB-104 for further details.

Notes:
1. Fan performance for 60, 70 and 75 ton rooftops are identical. However, note maximum motor hp size for each size. Contact your local Trane representative for information on
non-standard motors.
2. Shaded areas at table extremes note non-standard Bhp or Rpm selection. Contact your local Trane representative for more information.
3. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static must be added to appropriate component
static pressure drops (evaporator coil, filters, optional economizer, optional exhaust fan, optional heating system, optional cooling only extended casing, optional roof curb).
4. Maximum Cfm (for UL approval) as follows: 60 Ton — 27,000 Cfm , 70 & 75 Ton — 30,000 Cfm
5. Minimum motor horsepower is 10 hp.
6. Maximum motor horsepower is 40 hp.
7. Maximum motor Rpm is 1,130.
8. See RT-EB-104 for further details.

Notes:
1. Fan performance for 60, 70 and 75 ton rooftops are identical. Contact your local Trane representative for information on non-standard motors.
2. Shaded areas at table extremes note non-standard Bhp or Rpm selection. Contact your local Trane representative for more information.
3. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static must be added to appropriate component
static pressure drops (evaporator coil, filters, optional economizer, optional exhaust fan, optional heating system, optional cooling only extended casing, optional roof curb).
4. Maximum Cfm (for UL approval) as follows: 60 Ton — 27,000 Cfm, 70 & 75 Ton — 30,000 Cfm
5. Minimum motor horsepower is 10 hp.
6. Maximum motor horsepower is 40 hp.
7. Maximum motor Rpm is 1,130.
8. See RT-EB-104 for further details.

Notes:
1. Shaded areas indicate non-standard BHP or RPM selections. Contact your local Trane representive for more information.
2. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static must be added to appropriate component
static pressure drops, (evaporator coil, filters, optional economizer, optional heating system, optional roof curb).
3. Maximum 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. Minimum motor 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 more information.
2. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static must be added to appropriate component
static pressure drops, (evaporator coil, filters, optional economizer, optional heating system, optional roof curb).
3. Maximum 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. Minimum motor 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 more information.
2. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static must be added to appropriate
component static pressure drops, (evaporator coil, filters, optional economizer, optional heating system, optional roof curb).
3. Maximum 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. Maximum Cfm as follows: 105 Ton Std. — 44,000 Cfm, 105 Hi-Cap., 115, 130 Ton — 46,000 Cfm
5. Minimum motor horsepower is 30 hp.
6. See RT-EB-104 for further details.

Notes:
1. Shaded areas indicate non-standard BHP or RPM selections. Contact your local Trane representive for more information.
2. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static must be added to appropriate component
static pressure drops, (evaporator coil, filters, optional economizer, optional heating system, optional roof curb).
3. Maximum 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. Maximum Cfm as follows: 105 Ton Std. — 44,000 Cfm, 105 Hi-Cap., 115, 130 Tons — 46,000 Cfm
5. Minimum motor horsepower is 30 hp.
6. See RT-EB-104 for further details.

Human Interface Panel.

Controls

(VAV Units)

Inlet guide vane assemblies installed on
the supply fan inlets regulate fan
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.

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.
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.

The opening of the inlet guide vanes and
VAV boxes are coordinated during unit
start up and transition to/from Occupied/
Unoccupied modes to prevent
overpressurization of the supply air
ductwork. However, if for any reason the
supply air pressure exceeds the userdefined supply air static pressure limit
that was set at the Human Interface
Panel, the supply fan/VFD is shut down
and the inlet guide vanes (if included) are
closed. The unit is then allowed to restart
three times. If the overpressurization
condition occurs on the third time, the
unit is shut down and a manual reset
diagnostic is set and displayed at the
Human Interface Panel.

Supply Air Temperature Controls
Cooling/Economizer
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
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.
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.
At outdoor air conditions above the
enthalpy control setting, mechanical
cooling only is used and the fresh 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
outdoor air, if rooftop is equipped with 0
to 25 percent manual fresh air damper.

Heating: Hot Water or Steam

Supply Air Setpoint Reset

On units with hot water or steam
heating, the supply air temperature can
be controlled to a heating set point
during the Occupied mode.The supply
air temperature heating set point and
deadband are user-defined at the Human
Interface Panel. VAV Occupied heating on
hot water and steam heat units is
enabled by closing a field-supplied
switch or contacts connected to an
changeover input on the RTM.

Supply air reset can be used to adjust
the supply air temperature setpoint on
the basis of a zone temperature or on
outdoor air temperature. Supply air reset
adjustment is available from the Human
Interface Panel for supply air heating and
supply air cooling control.

temperature deadband low end, the
heating valve is modulated open to
maintain the set minimum supply air
temperature.

Heating: Modulating Gas
Upon a call for heating, the UCM closes
the heating contacts, beginning the firing
sequence. First, the heat exchanger
combustion blower begins operation.
Upon positive proving of combustion
airflow, a pre-purge cycle is executed.
Then the ignition sequence takes place.
If ignition is not proven, the ignition
transformer is de-energized. After a time
delay, another pre-purge cycle takes
place, followed by another attempt to
ignite. If ignition fails a second time, the
heating section will be shut down and
locked out until manually reset at the
unit mounted Human Interface Panel.
As additional heat is required, the air
damper opens, increasing the firing rate.
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 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, deenergizing the heat.The specific
sequence of operation of the gas heat
will depend on the size of the heat
exchanger.

A
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.
Outdoor air heating reset is the inverse
of cooling, with the same principles
applied.
For both outdoor air cooling reset and
heating reset, there are three user
defined parameters that are adjustable
through the Human Interface Panel.
- beginning reset temperature
- ending reset temperature
- maximum amount of temperature reset
B
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 userdefined parameters are the same as for
outdoor air reset.

3
Zone Temperature Control
Unoccupied Zone Heating and Cooling
During Unoccupied mode, the unit is
operated as a CV unit. Inlet guide vanes
and VAV boxes are driven full open.The
unit controls zone temperature within
the Unoccupied zone cooling and
heating (heating units only) deadbands.
Daytime warm-up
This feature is available on all types of
heating units. During Occupied mode, if
the zone temperature falls to a preset,
user-defined zone low limit temperature
setpoint the unit is put into Unoccupied
mode and Daytime Warm-up is initiated.
The system changes over to CV heating
(full unit airflow), the VAV boxes are fully
opened and full heating capacity is
provided until the Daytime Warm-up
setpoint is reached.The unit is then
returned to normal Occupied mode.
4
Outdoor Air CFM Compensation
The purpose of this feature is to
modulate the minimum position of the
economizer to compensate for varying
unit airflows in VAV units, thereby
minimizing the large variation of outdoor
air CFM that can occur. The feature
allows the user to set (calibrate) the
economizer minimum position with inlet
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).

Gas Heating - Two-Stage

Occupied Zone Temperature Control

Upon a call for heating, the UCM closes
the first stage heating contacts
beginning the firing sequence. First, the
heat exchanger combustion blower
begins operation. Upon positive proving
of combustion airflow, a pre-purge cycle
is executed.Then the ignition sequence
takes place.

Cooling/Economizer
During Occupied cooling mode, the
economizer (if provided) and mechanical
cooling are used to control zone
temperature. If the enthalpy of outside
air is appropriate to use “free cooling”,
the economizer will be used first to
attempt to satisfy the cooling zone
temperature setpoint; then the
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.
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 economizer control, outdoor air
enthalpy must be below the enthalpy of

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
outdoor air, if rooftop is equipped with 0
to 25 percent manual fresh air damper.

If ignition is not proven, the ignition
transformer is de-energized. After a time
delay another pre-purge cycle takes
place followed by another attempt to
ignite. If ignition fails a second time, the
cycle repeats on 235 and 350 MBh
modules. 500, 850 and 1000 MBh
modules, the heating section will be
shut down and locked out until manually
reset at the unit mounted Human
Interface Panel.
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.
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

sequenced based on load demand.

B
Supply Air Tempering
For gas and electric heat units in the Heat
mode but not actively heating, if the
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.
C
Auto Changeover
When the System Mode is “Auto,” the
mode will change to cooling or heating
as necessary to satisfy the zone cooling
and heating setpoints.The zone cooling
and heating setpoints can be as close as
2 F apart.

Unoccupied Zone Temperature Control
Cooling and Heating
Both cooling or heating modes can be
selected to maintain Unoccupied zone

Hot Water or Steam Heating
Upon a call for heat, the UCM will send a
varying voltage signal to the valve
actuator. The valve will modulate to meet
building demand as indicated by the
voltage signal. When heating is satisfied,
the valve will modulate closed.
A temperature sensor is located on the
coldest section of the coil. When it
senses an impending freeze condition, a
signal is sent to the hydronic valve to

warm-up is used to overcome the
“building sink” effect. Cycling capacity
MWU will operate until MWU setpoint is
reached or for 60 minutes, then the unit
switches to Occupied mode.

Space Pressure Control — Statitrac™
A pressure transducer is used to
measure and report direct space
(building) static pressure.The userdefined 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.
2
Morning Warm-up
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
capacity.
A
Full Capacity Morning Warm-up (MWU)
Full capacity Morning Warm-up uses full
heating capacity, and heats the zone up
as quickly as possible. Full heating
capacity is provided until the Morning
Warm-up setpoint is met. At this point,
the unit is released to Daytime mode.
B
Cycling Capacity Morning Warm-up
(MWU)
Cycling capacity Morning Warm-up
provides a more gradual heating of the
zone. Normal zone temperature control
with varying capacity is used to raise the
zone temperature to the MWU zone
temperature setpoint.This method of

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.
3
Ventilation Override (VOM)
The user can customize up to five (5)
different override sequences for
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.
UNIT OFF sequence “A”
When complete system shut down is
required the following sequence could
be used.
- Supply fan - Off.
- Supply fan VFD - Off (0 Hz) (if
equipped)
- Inlet guide vanes - Closed
(if equipped).
- Exhaust fan - Off, exhaust dampers Closed (if equipped).
- Exhaust fan VFD - Off (0 Hz) (if
equipped)
- Outside air dampers - Closed.
- Heat - all stages - Off, Modulating heat
output at 0 vdc.
- Occupied/Unoccupied output Deenergized
- VO relay - Energized
PRESSURIZE sequence “B”
Perhaps a positively pressurized space is
desired instead of a negatively
pressurized space. In this case, the
supply fan should be turned on with inlet

(if equipped).
- Exhaust fan - Off, exhaust dampers Closed (if equipped).
- Exhaust fan VFD - Off (0 Hz) (if
equipped)
- Outside air dampers - Open.
- Heat - all stages - Off, Modulating heat
output at 0 vdc.
- Occupied/Unoccupied output Energized
- VO relay - Energized

- Exhaust fan - On, exhaust dampers Open (if equipped).
- Exhaust fan VFD - On (60 Hz) (if
equipped)
- Outside air dampers - Open.
- Heat - all stages - Off, Modulating heat
output at 0 vdc.
- Occupied/Unoccupied output Energized
- VO relay - Energized

EXHAUST sequence “C”
With only the exhaust fans running
(supply fan off), the space that is
conditioned by that rooftop would
become negatively pressurized.This is
desirable for clearing the area of smoke
from the now-extinguished fire, possibly
keeping smoke out of areas that were
not damaged.
- Supply fan - Off.
- Supply fan VFD - Off (0 Hz) (if
equipped)
- Inlet guide vanes - Closed
(if equipped).
- Exhaust fan - On, exhaust dampers Open (if equipped).
- Exhaust fan VFD - On (60 Hz) (if
equipped)
- Outside air dampers - Closed.
- Heat - all stages - Off, Modulating heat
output at 0 vdc.
- Occupied/Unoccupied output Deenergized
- VO relay - Energized
PURGE sequence “D”
Possibly this sequence could be used for
purging the air out of a building before
coming out of Unoccupied mode of
operation on VAV units or when the
purging of smoke or stale air is required
after a fire.
- Supply fan - On.
- Supply fan VFD - On (60 Hz) (if
equipped)
- Inlet guide vanes/VAV boxes - Open
(if equipped).

80

PURGE with duct pressure control “E”
This sequence can be used when supply
air control is required for smoke control.
- Supply fan - On.
- Supply fan VFD - On (if equipped)
- Inlet guide vanes/VFD controlled by
supply air pressure control function
with supply air pressure high limit
disabled.
- Exhaust fan - On, exhaust dampers Open (if equipped).
- Exhaust fan VFD - On (60 Hz) (if
equipped)
- Outside air dampers - Open.
- Heat - all stages - Off, Modulating heat
output at 0 vdc.
- Occupied/Unoccupied output Energized
- VO relay - Energized
Note: Each system (cooling, exhaust,
supply air, etc.) within the unit can be
redefined in the field for each of the five
sequences, if required. Also the
definitions of any or all of the (5) five
sequences may be locked into the
software by simple key strokes at the
Human Interface Panel.

are two types of demand limiting, 50%
and 100%. When demand limiting is
needed, mechanical cooling and heating
operation are either partially (50%), or
completely disabled (100%), in order to
save energy.The definition of Demand

Night Setback Sensors
Trane’s night setback sensors are
programmable with a time clock function
that provides communication to the
rooftop unit through a 2-wire
communications link.The desired
transition times are programmed at the
night setback sensor and communicated
to the rooftop.
Night setback (unoccupied mode) is
operated through the time clock
provided in the sensors with night
setback. When the time clock switches to
night setback operation, the outdoor air
dampers close and heating/cooling can
be enabled or disabled depending on
set-up parameters. As the building load
changes, the night setback sensor
energizes the rooftop heating/cooling (if
enabled) function and the evaporator
fan.The rooftop unit will cycle through
the evening as heating/cooling (if
enabled) is required in the space. When
the time clock switches from night
setback to occupied mode, all heating/
cooling functions begin normal
operation.
When using the night setback options
with 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
temperature control of the building.

This input accepts a field supplied switch
or contacts closure such as a time clock.
Trane Tracer® System

This function is operational when the
RTM is the zone temperature sensor
source, which was set up at the Human
Interface Panel. When this function is
initiated by the push of a override button
on the ICS sensor, the Tracer will switch
the unit to the Occupied mode. Unit
operation (Occupied mode) during timed
override is terminated by a signal from
Tracer.
Timed Override Activation — Non-ICS

Reference Enthalpy Control of
Economizer
The optional reference enthalpy
compares ambient temperature and
humidity to the economizer enthalpy
control setpoint. If ambient temperature
and humidity are below the economizer
enthalpy control setpoint the economizer
will operate freely.This system provides
more sophisticated control where
outdoor air humidity levels may not be
acceptable for building comfort and
indoor air quality.
Dry Bulb Temperature Control of
Economizer

This function is active whenever the
RTM is selected as the ZoneTemperature
Sensor source, which was set up at the
Human Interface Panel. When this
function is initiated by the push of an
override button on the zone sensor, the
unit will switch to the Occupied mode.
Automatic Cancellation of theTimed
Override Mode occurs after three hours
of operation.

The optional dry bulb system measures
ambient temperature comparing it to the
economizer control temperature
setpoint. If the ambient temperature is
below the economizer dry bulb
temperature control setpoint, the
economizer will operate freely.This
system is best suited for arid regions
where the humidity levels of fresh air
would not be detrimental to building
comfort and indoor air quality.

Low Ambient Compressor Lockout

Compressor Lead/Lag

This function will lock out the
compressor if the outdoor air
temperature is below the low ambient
compressor lock out temperature set
point.The factory setpoint is 50 F on
standard units and 0 F on low ambient
units.This setpoint is adjustable at the
Human Interface Panel. Compressors
will be locked out when outdoor air
temperatures falls below that selected
temperature and will be allowed to start
again when the temperature rises 5 F
above the setpoint.

Compressor lead/lag is a user-selectable
feature through the Human Interface
Panel available on all units. After each
request for compressor operation, the
lead refrigeration circuit or compressor
on 20-30 tons units switches, thereby
causing a more equitable or balanced
run time among compressors.

Electrical Service Sizing
To correctly size electrical service
wiring for your unit, find the
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.
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
DataTables on the following page.)
LOAD1 = CURRENT OFTHE LARGEST
MOTOR (COMPRESSOR OR FAN
MOTOR)
LOAD2 = SUM OFTHE CURRENTS OF
ALL REMAINING MOTORS
LOAD3 = CURRENT OF ELECTRIC
HEATERS
LOAD4 = ANY OTHER LOAD RATED AT
1 AMP OR MORE
Set 1. Cooling Only Rooftop Units and
Cooling with Gas Heat Rooftop Units
MCA = (1.25 x LOAD1) + LOAD2 +
LOAD4

then reselect the RDE value to equal the
MOP value.
Set 2. Rooftop units with Electric Heat
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.
(Keep in mind when determining LOADS
that the compressors don’t run while the
unit is in the heating mode).
For units using heaters less than 50 kw.
MCA = 1.25 x (LOAD1 + LOAD2 + LOAD4)
+ (1.25 x LOAD3)
For units using heaters equal to or
greater than 50 kw.
MCA = 1.25 x (LOAD1 + LOAD2 + LOAD4)
+ LOAD3
The nameplate MCA value will be the
larger of the cooling mode MCA value or
the heating mode MCA value calculated
above.
MOP = (2.25 x LOAD1) + LOAD2 + LOAD3
+ LOAD4

MOP = (2.25 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.

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,
provided the reselected fuse size does
not exceed 800 amps.

RDE = (1.5 x LOAD1) + LOAD2 + LOAD4

RDE = (1.5 x LOAD1) + LOAD2 + LOAD3 +
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,

RT-PRC010-EN

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.
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.
MCA = (1.25 x LOAD3)
MOP = (1.25 x LOAD3)
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).
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.
RDE = LOAD3
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.
GENERAL NOTES:
On 20 to 130 ton rooftops, the selected
MOP value is stamped in the MOP field
on the nameplate.

The selection RDE value will be the larger
of the cooling mode RDE value or the
heating mode RDE value calculated
above.

Note:
1. The return opening of the roof curb is provided with an adjustable filler panel six inches wide. This panel allows adjustment of the return air opening in order to clear roof members of all
standard roof constructions with both the supply and return openings. The return air opening of the curb is at a 90 degree angle as compared to the rooftop return air opening to allow
this placement flexibility. The curb acts as a plenum between the ductwork and the unit return opening. A retainer clip is used to secure the adjustable filler piece to the roof curb.
*“P” dimension is 5’ 6” on 60, 70, 75 Tons SEHF (Units with electric heat).
**“R” dimension is 2’ 5 1/8” on 60, 70, 75 Tons SEHF (Units with electric heat).
