Designed For The 21st Century And Beyond
Trane commercial rooftops are moving
into the 21st century! Innovative
technology and new features have been
incorporated in the IntelliPak® Rooftops
to meet the demanding requirements of
the coming years.
Trane’s rooftop Unit Control Module
(UCM) is an innovative, modular
microprocessor control design that
actually replaces the electromechanical
controls on large rooftops. The UCM
coordinates the actions of the rooftop in
an efficient manner and provides standalone operation of the unit. Access to
the unit controls is via a Human
Interface Panel which is a standard
component of the IntelliPak rooftop.
This panel provides a high degree of
control, superior monitoring capability,

Rooftop Systems:
Profitable, Simple
Integrated Comfort™
System (ICS)
Trane integrated rooftop systems make
design and installation of rooftop comfort
systems profitable and easy. The
Integrated Comfort™ system (ICS)
improves job profit and increases job
control by combining Trane rooftop units
and a Tracer® building management
system. This integrated system provides
total building comfort and control. The
primary motivation for building owners/
managers in making the purchasing
decision of HVAC controls system is no
longer just saving energy; it is having the
ability to automate their facilities and the
convenience of interface to control
systems.
and unmatched diagnostic information
using a 2 line, 40 character per line,
English language display. There are no
diagnostic “codes” requiring a
translation key for interpretation. All
system status information and control
adjustments can be made from the
onboard Human Interface Panel.
The IntelliPak rooftop can optionally be
configured for direct communication
with a Tracer® building management
system using a twisted pair of wires.
This link brings all the status data and
control adjustment features of the
IntelliPak rooftop to a central location for
centralized building control on-site or
from a remote location.
the factory. All the status information
and editing data from the rooftop units,
VAV boxes, lighting, exhaust and other
auxiliary equipment is available from
Tracer for control, monitoring and
service support of your facility. Tracer, a
family of building automation products
from Trane, is designed with robust,
application specific software packages
to minimize custom programming
requirements and enable system setup
and control through simple editing of
parameters in the standard applications

The modular control design of the UCM
allows for greater application flexibility.
Customers can order exactly what the
job requires as options, 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
2) interface with Trane’s Tracer®
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.
Statitrac™ Direct Space
Building Pressurization
Control
Trane’s Statitrac™ control is a highly
accurate and efficient method of
maintaining building pressure control
with a large rooftop air conditioner.
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.
4
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.
FC Fans With Inlet
Guide Vanes
Trane’s foward-curved 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 of a
Trane FC fan with inlet guide vanes
result in superior part load performance.
Variable Frequency Drives
(VFD)
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.
Features and
Benefits
• 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.
The Trane 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 with torque
variations that are only 30 percent of
that produced by a reciprocating
compressor. This means the scroll
compressor imposes very little stress on
the motor for greater reliability. Low
torque variation means reduced noise
and vibration.
Suction Gas Cooled Motor
Compressor motor efficiency and
reliability is further optimized with this
design. Cool suction gas keeps the
motor cooler for longer life and better
efficiency.
Proven Design Through Testing and
Research
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 makes Trane the
worldwide leader in air conditioning
scroll compressor technology.
One of two matched scroll plates - the
distinguishing feature of the scroll
compressor.

3-D Scroll compressor vs reciprocating
compressor.

EXHAUST AIR OPTIONS
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.
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
100 percent modulating exhaust with
Statitrac™ direct space sensing building
pressurization control (with or without
variable frequency drives).
2
100 percent modulating exhaust without
Statitrac.
3
50 percent power exhaust.
4
Barometric relief dampers.
Application Recommendations
1
100 percent modulating exhaust with
Statitrac™ control
For both CV and VAV rooftops, the 100
percent modulating exhaust discharge
dampers (or VFD) are modulated in
response to building pressure. A
differential pressure control system,
called Statitrac™, uses a differential
pressure transducer to compare indoor
building pressure to atmospheric
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:
a
The exhaust fan runs only when needed
to lower building static pressure.
b
Statitrac compensates for pressure
variations within the building from
remote exhaust fans and makeup
air units.
c
The exhaust fan discharges in a single
direction resulting in more efficient fan
operation compared to return fan
systems.
11
d
Because discharge dampers modulate
the airflow, the exhaust fan may be
running unloaded whenever the
economizer dampers are less than
100 percent open.
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. The Trane 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.
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 of The Trane
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
Figure 12-1 — Plan View of Modulating 100 Percent Exhaust System
12
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 13-1 and 14-1.
These openings are used for the
discharge and return. No special curb
is needed.
• SXHF, SFHF, SLHF, SSHF Units
Figure 13-1 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
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 13-1, 2 and 3 show dimensions
for those panels.
• Horizontal Discharge On
SXHF, SFHF, SLHF and SSHF
Rooftops
(20 through 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.
Note 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.
Note 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.
Note 3) Supply and Return Base
openings must be covered when
converting to a horizontal configuration.

Application
Considerations
• SXHG, SLHG, SSHG Units
Figure 14-1 is a simplified sketch
showing which panels can be used for
horizontal supply and/or return. On all
90 through 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). See Tables 14-1 and 2 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.

Application
Considerations
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 through 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.
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 through 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. See Table 57-1
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
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 or Tracer®. Any or all
five sequences may be “locked” in by
15
the user at the Human Interface
Panel.

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 userdefined 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
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 34-1, 2 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
Application
Considerations
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.
3
If the roof structure is very light, roof
joists should be replaced by a
structural shape in the critical areas
described above.
4
If several units are to be placed on
one span, they should be staggered to
reduce deflection over that span.
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.
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 through 130 tons. Ask
your local Trane 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.
The Trane 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 from Trane’s
Customer Direct Service Network™
(C.D.S.), ask your local Trane
representative for additional
information on this program.
Clearance Requirements
The recommended clearances
identified with unit dimensions should
be 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:
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.
16
• 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
local Trane 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 17-1 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
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.
diameters to allow the conversion of
fan energy from velocity pressure to
static pressure.
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
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 17-2.

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
Table 26-1, 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 +
(0.10) (95 - 80) = 80 + 1.5
= 81.5 F
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

Leaving enthalpy = h(ent WB) h(diff). From Table 21-1 h(ent WB) =
30.9 Btu/lb
Leaving enthalpy = 30.9 Btu/lb - 7.12

From Table 35-3, kw may be selected
for a nominal 50-ton unit operating
460-volt power. The 170 kw heat
module (580.1 MBh) will satisfy the
winter heating load of 563 MBh.
Table 35-1 shows an air temperature
rise of 30.6 F for 17,500 cfm through
the 170 kw heat module.
Unit supply temperature at design
heating conditions = mixed air
temperature + air temperature rise =
65.4 F + 30.6 F = 96.0 F.
Gas Heating System (Natural Gas)
From Table 34-1 select the high heat
module (697 MBh output) to satisfy
winter heating load of 563 MBh at
unit cfm.
19
Hot Water Heating
Assume a hot water supply temperature
of 190 F. Subtract the mixed air
temperature from the hot water
temperature to determine the ITD (initial
temperature difference).
ITD = 190 F - 65.4 F = 125 F. Divide the
winter heating load by ITD = 563 MBh ÷
125 F = 4.50 Q/ITD.
From Table 36-1, select the low heat
module. By interpolation, a Q/ITD of
4.50 can be obtained at a gpm at 25.7.
Water pressure drop at 25.7 gpm is
0.57 ft. of water. Heat module
temperature rise is determined by:

Selection
Procedure
Steam Heating System
Assume a 15 psig steam supply.
From Table 34-4, the saturated
temperature steam is 250 F. Subtract
mixed air temperature from the steam
temperature to determine ITD. ITD =
250 F - 65.4 F = 185 F.
Divide winter heating load by ITD =
563 MBh ÷ 185 F = 3.04 Q/ITD.
From Table 34-3, select the high heat
module. The high heat module at
17,500 cfm has a Q/ITD = 5.11.
Heat module capacity, Q = ITD x
Q/ITD = 185 F x 5.11 Q/ITD =
945 MBh
Heat module air temperature rise
Total Btu
=
1.085 x Supply cfm
945 Btu ÷ (1.085 x 17,500 cfm)

Unit supply temperature at design
conditions = mixed air temperature + air
temperature rise = 65.4 F + 49.8 F
= 115 F.
AIR DELIVERY PROCEDURE
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).
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. Enter Table 58-1
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 57-1) =
0.12 inches
Total return system negative static
pressure = 0.77 inches
Exhaust fan cfm = 12,000 cfm
From Table 59-1, the required bhp is
3.45 hp at 574 rpm. Thus, the exhaust
fan motor selected is 5 hp.
To select a drive, enter Table 60-1 for a
5 hp motor for a 50 ton unit. Drive
selection number 6 — 600 rpm.
Where altitudes are significantly above
sea level, use Tables 21-2 and 21-3 and
Figure 21-1 for applicable correction
factors.
UNIT ELECTRICAL REQUIREMENTS
Selection procedures for electrical
requirements for wire sizing amps,
maximum fuse sizing, and dual element
fuses are given in the electrical service
section of this catalog.
Altitude Corrections
The rooftop performance tables and
curves of this catalog are based on
standard air (.075 lbs/ft). If the rooftop
airflow requirements are at other than
standard conditions (sea level), an air
density correction is needed to project
accurate unit performance.
Figure 21-1 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 21-1.
2
Divide the static pressure at the
nonstandard condition by the air
density ratio to obtain the corrected
static pressure.
3
Use the actual cfm and the corrected
static pressure to determine the fan rpm
and bhp from the rooftop performance
tables or curves.
4
The fan rpm is correct as selected.
5
Bhp must be multiplied by the air
density ratio to obtain the actual
operating bhp.
In order to better illustrate this
procedure, the following example is
used:
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.
20
1
From Figure 21-1, the air density ratio is
0.86.
2
Tsp = 3.0-inches / 0.86 = 3.49
inches tsp.
3
From the performance tables: a 60-ton
rooftop (without inlet vanes) will deliver
18,000 cfm at 3.49-inches tsp at 906
rpm and 21.25 bhp.
4
The rpm is correct as selected 906 rpm.
5
Bhp = 21.25 x 0.86 = 18.3 bhp actual.
Compressor MBh, SHR, and kw should
be calculated at standard and then
converted to actual using the correction
factors in Table 21-2. 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 in Table 21-3 before
calculating the heating supply air
temperature.

Notes:
1. Maximum permitted air temperature rise; 20-30 ton (UL — 50 F) (CSA — 60 F), 40 — 60 ton (UL/CSA — 50 F).
2. Air temperature rise = kw x 3413 ÷ (scfm x 1.085)
3. All heaters on units provide 3 increments of capacity.
4. 200 and 230 volt electric heat rooftops require dual power supplies to the control box. All other rooftops have single power connections. See Electrical Data Section for electrical sizing
information.

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.
7. Maximum 3 hp and 5 hp motor Rpm is 1,100, maximum
6. Maximum motor horsepower as follows: 20 Ton — 15 hp
7.5 hp through 15 hp motor Rpm is 1655.
25 Ton — 15 hp

Notes:
1. Shaded areas at table extremes note non-standard Bhp or Rpm selection. Contact your local Trane representative 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 exhaust fan, optional heating system, optional cooling only extended casing, optional roof curb).
3. Minimum motor horsepower is 5 hp, maximum motor horsepower is 20 hp. Maximum RPM is 1379.
4. Max Cfm (for UL approval) as follows: 30 Ton-13,500 Cfm.

(See following page for Fan Performance Chart)
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 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.

(See following page for Fan Performance Chart)
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.

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’’ H 20.
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’’ H 20.
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’’ H 20.
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’’ H 20.
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.

Electrical Service Sizing
Set 2. Rooftop units with Electric Heat
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.
a. Single Source Power (380V, 415V,
460V, and 575V)
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 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.
LOAD1 = CURRENT OF THE
LARGEST MOTOR (COMPRESSOR
OR FAN MOTOR)
MCA = 1.25 x (LOAD1 + LOAD2 +
LOAD4) + (1.25 x LOAD3)
LOAD2 = SUM OF THE CURRENTS
OF ALL REMAINING MOTORS
For units using heaters equal to or
greater than 50 kw.
LOAD3 = CURRENT OF ELECTRIC
HEATERS
MCA = 1.25 x (LOAD1 + LOAD2 +
LOAD4) + LOAD3
LOAD4 = ANY OTHER LOAD RATED
AT 3 AMPS OR MORE
The nameplate MCA value will be the
larger of the cooling mode MCA value
or the heating mode MCA value
calculated above.
Set 1. Cooling Only Rooftop Units and
Cooling with Gas Heat Rooftop Units
MCA = (1.25 x LOAD1) + LOAD2 +
LOAD4
MOP = (2.25 x LOAD1) + LOAD2 +
LOAD4
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
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.
MOP = (2.25 x LOAD1) + LOAD2 +
LOAD3 + 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.
RDE = (1.5 x LOAD1) + LOAD2 +
LOAD3 + LOAD4
The selection RDE value will be the
larger of the cooling mode RDE value
or the heating mode RDE value
calculated above.
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 through 130 ton rooftops, the
selected MOP value is stamped in
the MOP field on the nameplate.

Sequence Of Operation
NOTE: When noted in this sequence
“Human Interface Panel,” the reference
is to both the unit mounted and remote
mounted Human Interface Panel. All
setpoint adjustments can be
accomplished at the unit or Remote
Human Interface Panel.
1
Supply Air Pressure Control
• 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 range is
determined by the supply air pressure
setpoint and supply air pressure
deadband, which are set through the
Human Interface Panel.
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.
Controls
• Supply Air Static Pressure Limit
The opening of the inlet guide vanes
and VAV boxes are coordinated during
unit start up and transition to/from
Occupied/Unoccupied modes to
prevent overpressurization of the
supply air ductwork. However, if for any
reason the supply air pressure exceeds
the user-defined 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.
2
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 ambient
conditions are below the enthalpy
control setting or below the return air
enthalpy if unit has comparative
enthalpy installed. If outside air is not
suitable for “economizing,” the fresh air
dampers drive to the minimum open
position. A field adjustable, factory
default setting in the Human Interface
Panel or Tracer® or a remote
potentiometer can provide the input to
establish the minimum damper
position.
65
Variable Air
Volume
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
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.
• 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, de-energizing the heat.
The specific sequence of operation of
the gas heat will depend on the size of
the heat exchanger.
• Supply Air Setpoint Reset
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.
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 user-defined parameters are the
same as for outdoor air reset.
• Supply Air Tempering
Hot water, steam, and modulating gas
units only — When supply air
temperature falls below the supply air
temperature deadband low end, the
heating valve is modulated open to
maintain the set minimum supply air
temperature.
3
Zone Temperature Control
• Unoccupied Zone Heating and
Cooling
During Unoccupied mode, the unit is
operated as a CV unit. Inlet guide
Controls
Constant
Volume
vanes and VAV boxes are driven full
open. The unit controls zone
temperature within the Unoccupied
zone cooling and heating (heating
units only) deadbands.
Note that the economizer is only
allowed to function freely if ambient
conditions are below the enthalpy
control setting or below the return air
enthalpy if unit has comparative
enthalpy. If outside air is not suitable for
“economizing,” the fresh air dampers
drive to the minimum open position. A
field adjustable, factory default setting
in the Human Interface Panel or
Tracer® or a remote potentiometer can
provide the input to establish the
minimum damper position.
• 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 Warmup 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).
CV Units Only
Sequence Of Operation
1
Occupied Zone Temperature Control
• 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.
66
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.
A
Heating
• Gas Heating - Two-Stage
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 prepurge 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 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
Controls
heating relay, de-energizing the second
stage of heat. When the requirement is
fully satisfied, the first stage contacts are
opened, de-energizing the first stage of
heat. The specific sequence of operation
of the gas heat will depend on the size of
the heat exchanger.
• Gas 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, de-energizing the heat. The
specific sequence of operation of the
gas heat will depend on the size of the
heat exchanger.
• Electric Heating
The three stages of electric heat will be
sequenced on the zone demand signal
from the zone sensor. The signal is sent
to the UCM and the stages are
sequenced based on load demand.
• 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
drive it full open. If the supply fan is on,
or if the outside air damper is open when
this freezing condition is sensed, the
supply fan is turned off and the outside
air damper is closed.
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.
2
Unoccupied Zone Temperature Control
• Cooling and Heating
Both cooling or heating modes can be
selected to maintain Unoccupied zone
temperature deadbands. For
Unoccupied periods, heating,
economizer operation or compressor
operation can be selectively locked out
at the Human Interface Panels.
Control Sequences of
Operation That Are Common
to Both VAV and CV Units
1
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
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.
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.
Controls
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 guide vanes open and the exhaust
fan should be turned off.
- Supply fan - On.
- Supply fan VFD - On (60 Hz) (if
equipped)
- Inlet guide vanes/VAV boxes - Open
(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 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).
- 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
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.
4
Human Interface Panel (H.I.)
The Human Interface (HI) Panel
provides a 2 line X 40 character clear
English liquid crystal display and a 16
button keypad for monitoring, setting,
editing and controlling. The Human
Interface Panel is mounted in the unit’s
main control panel and is accessible
through a hatch built into the unit’s
control panel door.
The optional remote-mount version of
the Human Interface (RHI) Panel has
68
all the functions of the unit-mount version
except Service Mode. To use a RHI the
unit must be equipped with an optional
InterProcessor Communications Bridge
(IPCB). The RHI can be located up to
1,000 feet from the unit. A single RHI can
be used to monitor and control up to 4
rooftops, each containing an IPCB.
•
•
•
•
•
•
The Main Menus of the Human
Interface panels are:
STATUS — used to monitor all
temperatures, pressures, humidities,
setpoints, input and output status. The
CUSTOM key allows the user to
customize a status report—consisting
of up to (4) screens of the data
available in the main Status menu.
SET POINTS — used to edit all factory
preset Default setpoints
DIAGNOSTICS — used to review active
and historical lists of diagnostic
conditions. A total of 49 different
diagnostics can be read at the Human
Interface Panel and the last 20
diagnostics can be held in a active
history buffer log at the Human
Interface Panel.
SETUP — Control parameters, sensor
selections, setpoint source selections,
output definitions, and numerous other
points can be edited in this menu. All
points have factory preset values so
unnecessary editing is kept to a
minimum.
CONFIGURATION — Preset with the
proper configuration for the unit as it
ships from the factory, this information
would be edited only if certain features
were physically added or deleted from
the unit. For example, if a field supplied
Trane Communication Interface (TCI)
module or Ventilation Override Module
was added to the unit in the field, the
unit configuration would need to be
edited to reflect that feature.
SERVICE — used to selectively control
outputs (for compressors, fans, damper
position, etc.) for servicing or
troubleshooting the unit. This menu is
accessible only at the unit-mounted
Human Interface Panel.

Generic Building Automation System
Module (GBAS)
The Generic Building Automation
System Module (GBAS) is used to
provide broad control capabilities for
building automation systems other than
the Trane’s Tracer® system. A field
provided potentiometer or a 0-5 vdc
signal can be applied to any of the
inputs of the GBAS to provide:
Controls
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.
a.
Analog Inputs — 4 Analog inputs that
can be configured to be any of the
following:
(1) Occupied Zone Cooling
(2) Unoccupied Zone Cooling
(3) Occupied Zone Heating
(4) Unoccupied Zone Heating
(5) SA Cooling Setpoint
(6) SA Heating Setpoint
(7) Space Static Pressure Setpoint
(8) SA Static Pressure Setpoint
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 setup 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.
b.
Binary Outputs — each of the five (5)
relay outputs can be mapped to any/all
of the available diagnostics.
c.
Demand Limiting Binary Input — This
function is operational on units with a
GBAS and is used to reduce electrical
consumption at peak load times. There
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 Limit is user definable at
the Human Interface Panel. Demand
Limit binary input accepts a field
supplied switch or contact closure.
When the need for demand limiting has
been discontinued, the unit’s cooling/
heating functions will again become
fully enabled.
6
Evaporator Coil Frost Protection —
FROSTAT™
A temperature sensor on the
evaporator is used to determine if the
coil is getting close to a freezing
condition. Mechanical cooling capacity
is shed as necessary to prevent icing.
The FROSTAT™ system eliminates the
need for hot gas bypass and adds a
suction line surface temperature sensor
near the TXV bulb location to shut the
cooling off when coil frosting conditions
occur. The supply fans are not shut off
and will de-ice the coil. Timers prevent
the compressors from rapid cycling.
7
Occupied/Unoccupied Switching
•
a.
Description — 3 ways to switch
Occupied/Unoccupied:
(1) NSB Panel
(2) Field-supplied contact closure
(hardwired binary input to RTM)
(3) TRACER
Night Setback Sensors
Trane’s night setback sensors are
programmable with a time clock
•
•
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.
Occupied/Unoccupied input on the
RTM
This input accepts a field supplied
switch or contacts closure such as a
time clock.
Trane Tracer® System
The Trane Tracer System can control
the Occupied/Unoccupied status of
the rooftop.
8
Timed Override Activation — ICS
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
This function is active whenever the
RTM is selected as the Zone
Temperature Sensor source, which
was set up at the Human Interface
69
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 the Timed Override
Mode occurs after three hours of
operation.
9
Low Ambient Compressor Lockout
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.
10
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.
Note: If Comparative Enthalpy is not
ordered, the standard method is to
compare outdoor air enthalpy with a
fixed reference enthalpy. The reference
enthalpy is set through the Human
Interface Panel.
11
Compressor Lead/Lag
Compressor lead/lag is a userselectable 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 ton units
switches, thereby causing a more
equitable or balanced run time
among compressors.
12
Emergency Stop Input
A binary input is provided on the
Rooftop Module (RTM) for installation
of field provided switch or contacts for
immediate shutdown of all unit
functions.
