Integrated

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.

Simplifying The Comfort System

At Trane, we think new technology and

innovation should bring you more

capabilities, more flexibility and at the

same time be able to give you

equipment and systems that are easier

to use, easier to install, commission and

service. The Rooftop Integrated Comfort

system saves you time and money by

simplifying system design and system

installation. When used with Trane’s DDC/

VAV boxes (or VariTrane™), system

balancing almost goes away because

each VAV box is commission and tested

before it leaves 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 software.

Should you select an Integrated Comfort

system for your facility, the

accountability for equipment,

automation and controls is Trane’s,

Trane’s, and Trane’s!

The IntelliPak® rooftop, as a part of an

Integrated Comfort system, provides

powerful maintenance monitoring,

control and reporting capabilities. The

Tracer places the rooftop in the

appropriate operating mode for

operation for: system on/off, night

setback, demand limiting , setpoint

adjustment based on outside

parameters and much more. Up to 48

different unit diagnostic conditions can

be monitored through Tracer to let you

know about things like: sensor failures,

loss of supply airflow, and a compressor

trip out. Further, the addition of Building

Management Network software offers

remote scanning, automatic receipt of

alarms, and easy dial-up access to over

100 various Tracer sites across town or

across the country.

Features and

Benefits

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

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.

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.

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; 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.

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 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.

9RT-PRC010-EN

Application

Considerations

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.

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 10 0 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.

RT-PRC010-EN10

Application

Considerations

Figure AC-1 — Plan View of Modulating 100 Percent Exhaust System

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 air-

moving 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 outside air entering

the building. Therefore, if selected for

more than 40 to 50 percent of supply

airflow, the building may become under-

pressurized when economizer operation

is allowing lesser amounts of outdoor air

into the building. If, however, building

pressure is not of a critical nature, the

non-modulating exhaust system may be

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.

Notes:

1. Add an extra 0.20-inches pressure drop to the supply external static to account for the extra turn the air is making.

2. The openings all have a 1.25-inch lip around the perimeter to facilitate ductwork attachment.

3. If exhaust fans are being used, provisions should be made for access to the exhaust components, since the access door is now being used as a return.

4. Use the dimensions provided and the supply Cfm to calculate the velocity (ft/min) through the openings to be sure they are acceptable.

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.

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 AC-

1, 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

RT-PRC010-EN12

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). See Tables 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

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.

Notes:

1. Add an extra 0.20-inches pressure drop to the

supply external static to account for the extra turn

the air is making.

support channel in between may be removed.

3. If exhaust fans are being used, provisions should

be made for access to the exhaust components,

since the access door is now being used as a

Application

Considerations

13RT-PRC010-EN

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. See Table

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

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 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

Application

Considerations

RT-PRC010-EN14

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.

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.

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 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:

•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 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

15RT-PRC010-EN

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.

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.

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.

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 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 +

(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

capacity.

(Table PD-43)

Unit Total Static Pressure 2.76 inches

Using total of 17,500 cfm and total

static pressure of 2.76 inches, enter Table

PD-36. Table PD-36 shows 15.3 bhp with

924 rpm.

From Chart SP-1 supply fan motor heat

gain = 46.0 MBh.

Step 4 — Determine Total Required

Cooling 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

From Table 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

Temperature

Unit sensible heat capacity corrected for

supply air fan motor heat = 426 MBh - 46

MBh = 380 MBh.

Supply air dry bulb temperature

difference =

Sensible Btu =

1.085 x Supply cfm

380 MBh ÷ (1.085 x 17,500 cfm)

Supply air dry bulb = 81.5 DB - 20.0

= 61.5 F

Unit enthalpy difference =

Total Btu =

4.5 x Supply cfm

561 MBh ÷ (4.5 x 17,500 cfm) =

7.12 Btu/lb

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

Btu/lb = 23.78 Btu/lb

Supply air wet bulb = 55.9

Leaving air temperature = 61.5

From Table PD-31, select the low heat

module. By interpolation, a Q/ITD of 4.50

Assume a 15 psig steam supply.

From Table PD-27, the saturated

Electric Heating System

Unit operating on 460/60/3 power supply.

From Table PD-30, 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 PD-28 shows an air temperature

From Table PD-26, select the high heat

module. The high heat module at 17,500

cfm has a Q/ITD = 5.11.

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 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

Total return system negative static

pressure = 0.77 inches

Exhaust fan cfm = 12,000 cfm

From Table PD-47, 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 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, use Tables PAF-2 and PAF-3 and

Figure PAF-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 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

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.

Selection

Procedure

19RT-PRC010-EN

Selection

Procedure

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.

1

From Figure PAF-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 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 in Table PAF-3 before

calculating the heating supply air

temperature.

HEATING CAPACITY SELECTION

Step 1 — Determine Air Temperature

Entering Heating Module

Mixed air temperature = RADB + % OA

(OADB - RADB) = 70 + (0.10) (0 - 70) = 63

F

Supply air fan motor heat temperature

rise = 46,000 Btu ÷ (1.085 x 17,500 cfm) =

2.42 F

Air temperature entering heating

module = 63.0 + 2.42 = 65.4 F

Notes:

1. Maximum permitted air temperature rise; 20-30 tons (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.

Performance

Data

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.

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.

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. 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.

NOTE: When noted in this sequence

“Human Interface Panel,” the reference is

to both the unit mounted and remote

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.

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 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.

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 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).

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.

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 control setting. For comparative

enthalpy economizer control, outdoor air

enthalpy must be below the enthalpy of

the return air.

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 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

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

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.

Controls

Control Sequences of

Operation 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 user-

defined control parameters used in this

control scheme are space static pressure

setpoint and deadband. As

the economizer opens, the building

pressure rises and enables the

exhaust fan and dampers or exhaust

VFD. The exhaust dampers or VFD then

modulate to maintain space pressure

within the deadband.

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.

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

(VAV/CV Units)

RT-PRC010-EN80

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 -

- 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.

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 all

the functions of the unit-mount version

except Service Mode. To use a RHI the

Controls (VAV/CV Units)

81RT-PRC010-EN

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.

Human Interface Panel Main Menu

• 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 unLitorder it 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

odule (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:

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

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

Controls (VAV/CV Units)

RT-PRC010-EN82

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.

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 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.

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 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.

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

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.

11

Compressor Lead/Lag

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.

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.

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

Data Tables on the following page.)

LOAD1 = CURRENT OF THE LARGEST

MOTOR (COMPRESSOR OR FAN

MOTOR)

LOAD2 = SUM OF THE 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

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.

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

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 to 130 ton rooftops, the selected

MOP value is stamped in the MOP field

on the nameplate.

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’ 51/8” on 60, 70, 75 Tons SEHF (Units with electric heat).

Table DD-3 — 20 - 75 Ton Downflow Roof Curb Dimensions (Ft. In.)

Figure DD-3 — 20 - 75 Ton Optional Roof Curb Dimensions (Downflow)

Note: The pedestal was purposely designed

13/8” shorter than the curb because the unit’s

base rails rest on the pedestal at one point

and on the curb at a different point.

Notes:

1. Provide unrestricted clearance over the condenser fans.

2. A minimum clearance of 2’ 4-1/2” is required to open the hinged control panel

doors. Both doors swing outward in a 180-degree arc.

3. A minimum clearance of 2’ 10-3’4” is required to open the access doors on the unit’s

supply fan, evaporator, filter and exhaust fan sections. All hinged doors swing

outward in a 180-degree arc.

4. 90-130 ton models have two outdoor air intakes located at the back

of the unit and one small outdoor air intake located at

the end of the unit.
