IntelliPak™ II Rooftop

Air Handlers

Designed For Today,

Tomorrow and Beyond

Built on the legacy of Trane's industry leading IntelliPak, the IntelliPak II

Air Handler platform is designed for the future. Expanded features and

benefits, controls enhancements and world class energy efficiencies

make the IntelliPak II the right choice for demanding applications

today, and tomorrow.

Trane's Unit Control Module (UCM), an innovative, modular

microprocessor control design, coordinates the actions of the

IntelliPak II Air Handler for reliable and efficient operation and allows

for standalone operation of the unit.

Access to the unit controls, via a Human Interface Panel, provides a

high degree of control, superior monitoring capability, and unmatched

diagnostic information.

Optionally, for centralized building control on-site, or from a remote

location, IntelliPak II can be configured for direct communication with

a Trane Tracer™ or a 3rd party building management system using

LonTalk®. With either of these systems, the IntelliPak II operating

status data and control adjustment features can be conveniently

monitored from a central location.

The IntelliPak II has the technology and flexibility to bring total comfort

to every building space.

Integrated Comfort with Trane

Tracer™ LCI

The Tracer Integrated Comfort™

System (ICS) improves job profit and

increases job control by combining

Trane rooftop air handler units with

the Trane Tracer building

management system. This integrated

system provides total building

comfort and control. Some of the

primary motivations for building

owners/managers in deciding to

purchase a HVAC controls system are

energy savings, cost control, and the

convenience of facility automation.

Simplifying the Comfort

System

Trane technology and innovation

brings more capabilities, more

flexibility, and offers equipment and

systems that are easy to use, easy to

Figure 8. Trane Complete Comfort System

IntelliPak™ II Air Handler

install, commission and service. The

Tracer Integrated Comfort system

saves time and money by simplifying

system design and system

installation.

When used with Trane DDC/VAV

terminals (or VariTrane™), system

balancing almost goes away because

each VAV box is commissioned and

tested before it leaves the factory.

All the status information and editing

data from the air handler units, VAV

terminals, lighting, exhaust and other

auxiliary equipment is available from

Tracer for facility control, monitoring

and service support. Tracer, a family

of building automation products

from Trane, is designed with robust,

application specific software

8RT-PRC031-EN

Features and Benefits

packages to minimize custom

programming requirements and

enable system setup and control

through simple editing of parameters

in the standard applications software.

When selecting an Integrated

Comfort system for a facility, the

accountability for equipment,

automation and controls is Trane's,

Trane's, and Trane's!

In addition to high quality, high

performance, packaged air handler,

Trane provides precise air delivery

management with VariTrane VAV

terminals.

Wireless zone sensors minimize the

installation costs of the VariTrane

terminals and the packaged air

handler system in general.

The IntelliPak™ II air handler, as a

part of an Integrated Comfort system,

provides powerful maintenance

monitoring, control and reporting

capabilities. The Tracer places the air

handler in the appropriate operating

mode for: system on/off, night

setback, demand limiting, setpoint

adjustment based on outside

parameters and much more.

Many different unit diagnostic

conditions can be monitored through

Tracer: sensor failures and loss of

supply airflow. 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.

Interoperability

Trane Tracer LonTalk Control

Interface (LCI) for IntelliPak II offers a

building automation control system

with outstanding interoperability

benefits.

LonTalk, which is an industry

standard, is an open, secure and

reliable network communication

protocol for controls, created by

Echelon Corporation and adopted by

the LonMark Interoperability

Association. It has been adopted by

several standards, such as: EIA-709.1,

the Electronic Industries Alliance

(EIA) Control Network Protocol

Specification and ANSI/ASHRAE 135,

part of the American Society of

Heating, Refrigeration, and Air

Conditioning Engineer's BACnet

control standard for buildings.

Interoperability allows application or

project engineers to specify the best

products of a given type, rather than

one individual supplier's entire

system. It reduces product training

and installation costs by

standardizing communications

across products. Interoperable

systems allow building managers to

monitor and control IntelliPak II

equipment with a Trane Tracer

Summit or a 3rd party building

automation system.

It enables integration with many

different building controls such as

access/intrusion monitoring, lighting,

fire and smoke devices, energy

management, and a wide variety of

sensors (temperature, pressure,

light, humidity, occupancy, CO2 and

air velocity). For more information on

LonMark, visit www.lonmark.org or

Echelon, www.echelon.com.

Optimum Building

Comfort Control

The modular control design of the

UCM allows for greater application

flexibility. Customers can order

exactly the options required for the

job, rather than one large control

package. Unit features are distributed

among multiple field replaceable

printed circuit boards. The Trane

UCM can be setup to operate under

one of three control applications:

1. standalone

RT-PRC031-EN 9

Features and Benefits

2. interface with Trane Tracer™

building management system

3. interface with a generic (non-

Trane) building management

system. All setup 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, with

the exception of the Service mode

which is not available on the Remote

Human Interface Panel. This common

interface feature requires less time

for building maintenance personnel

to learn to interact with the unit.

All air handler control parameters are

adjustable and can be setup through

the Remote Human Interface Panel

such as, but not limited to: system

on/off, demand limiting type, night

setback setpoints, and many other

setpoints. No potentiometers are

required for setpoint adjustment, all

adjustments are done through the

Remote Human Interface keypad.

Up to 56 different air handler

diagnostic points can be monitored

through the human interfaces such

as: sensor failures and loss of supply

airflow. No special tools are required

for servicing 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/service person can

diagnose the root cause of failures.

Figure 10. Statitrac

Statitrac™ Direct Space

Building Pressurization

Control

Trane Statitrac™ control is a highly

accurate and efficient method of

maintaining building pressure

control with a large air handler.

Building space pressurization control

is achieved with a 100 percent

modulating exhaust system that

features a single forward curved fan,

with modulating discharge dampers

that operates only when needed or a

100% modulating plenum return fan

with airfoil wheel that operates

continuously with the supply fan.

Most of the operating hours of the

100 percent modulating exhaust

system are at part load, resulting in

energy savings.

Statitrac, with the 100 percent

modulating exhaust system,

provides comfort and economy for

buildings with large air handler

systems. Statitrac, with the 100%

modulating plenum return fan

provides comfort and space pressure

control in more demanding

applications with high return static

pressure, and applications requiring

duct returns.

Statitrac control with exhaust fan is

simple! The space pressure control

turns the exhaust fans on and off as

required and modulates exhaust

dampers, or VFD speed, to maintain

space pressure within the space

pressure deadband. Economizer and

return air dampers are modulated

based on ventilation control and

economizer cooling request.

The unit mounted Human Interface

Panel can be used to:

1. adjust space pressure setpoint

2. adjust space pressure deadband

3. measure and read building static

pressure

The modulating exhaust system

maintains the desired building

pressure, while saving energy and

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 also be

maintained when a variable

frequency drive is used.

Statitrac Control with Plenum

Return Fan is State of the Art!

Other manufacturers utilize a fan

tracking control scheme whereby the

return fan speed tracks the supply fan

speed in a linear fashion. This

scheme works well at minimum and

maximum CFM airflow. However,

due to the dissimilar performance

characteristics of the supply and

return fan, building pressure is

difficult to control at points between

minimum and maximum CFM

airflow.

The Trane return fan/building

pressurization control system

eliminates the effects of dissimilar

supply/return fan characteristics

experienced in a linear tracking

control system by modulating the

exhaust dampers based on space

pressure, the return/economizer

dampers based on ventilation

requirements, and the return fan

speed based on return plenum static

pressure. The supply fan, return fan,

exhaust damper, and return/

economizer damper systems act

independently from one another to

maintain comfort and building

pressure.

The return fan operates whenever

the supply fan is in operation. The

unit exhaust dampers are modulated

in response to the space pressure

signal to maintain space pressure

within the space pressure deadband.

The unit economizer and return air

dampers are modulated based on

ventilation control, minimum outside

air economizer position, and

economizer cooling request. The

return fan speed is modulated based

on a return duct static pressure

deadband control. Using the unit

mounted Human Interface Panel you

can:

1. adjust space pressure setpoint

2. adjust space pressure deadband

3. measure and read building space

pressure

4. measure and read return duct

static pressure.

Proper building pressurization

eliminates annoying door whistling,

doors standing open, and odors from

other zones.

10 RT-PRC031-EN

Features and Benefits

Supply Fans with Inlet Guide

Vanes

Trane airfoil fans with inlet guide

vanes pre-rotate the air in the

direction of the fan wheel, decreasing

static pressure and horsepower,

essentially unloading the fan wheel.

The unloading characteristics result

in superior part load performance.

Variable Frequency Drives

(VFD)

Variable Frequency Drives are factory

installed and tested to provide

supply/exhaust/return fan motor

speed modulation. VFD's, as

compared to inlet guide vanes or

discharge dampers, are quieter, more

efficient, and may be eligible for

utility rebates. The VFD's are

available with or without a bypass

option. Bypass control will simply

provide full nominal airflow in the

event of drive failure.

RT-PRC031-EN 11

VAV Units Only

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.

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 or BAS/Network.

Inlet guide vane assemblies installed

on the supply fan inlets regulate fan

capacity and limit horsepower at

lower system air requirements.

Figure 11. IntelliPak™ II Control Panel

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 or BAS/Network.

Variable frequency drives provide

supply fan motor speed modulation.

The drive will accelerate or

decelerate as required to maintain

the supply static pressure setpoint.

When subjected to high ambient

return conditions the VFD will reduce

its output frequency to maintain

operation.

Bypass control is offered to provide

full nominal airflow in the event of

drive failure.

Supply Air Static Pressure

Limit

The opening of VAV terminals, and

the amount of supply air provided by

the inlet guide vanes, or variable

frequency drive are coordinated

during start up and transition to/from

Occupied/Unoccupied modes to

prevent over pressurization 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 over pressurization

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 and

BAS/Network.

Supply Air Temperature

Controls

Cooling/Economizer

During Occupied cooling mode of

operation, the economizer (if

available) and cooling are used to

control the supply air temperature.

The supply air temperature setpoint

and deadband are user-defined at

the Human Interface Panel.

The supply air temperature setpoint

may be user-defined from the BAS/

Network. If the conditions of the

outside air is appropriate to use

“free cooling,” the economizer will

be used first to attempt to satisfy the

supply air setpoint; then if required

the hydronic valve will be modulated

to maintain supply air temperature

setpoint.

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 supply air

Controls

Variable Air Volume (VAV) Only

Controls Variable Air Volume (VAV) Only

temperature from setpoint, i.e., the

further away from setpoint, the faster

the fresh air damper will open.

Note: 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.

The outdoor air dampers may be set

for a maximum of 25 percent outdoor

air, through the unit mounted Human

Interface Panel or a signal from the

BAS/network, if the air handler is

equipped with 0 to 25 percent

motorized fresh air dampers.

entering air side of the chilled water

coil, will send a signal to the hydronic

valve to drive it full open when a

potential freeze condition is detected.

The supply fan is then turned off and

the fresh air damper is closed.

Heating

Modulating Gas

Upon a call for heating, the HEAT

module closes the heating contacts,

beginning the firing sequence. First,

the heat exchanger combustion

blower begins operation. Upon

positive proving of combustion

airflow, a 60 second pre-purge cycle

is executed. Then the ignition

sequence takes place.

If ignition is not proven, the safety

control locks out and must be

manually reset. As long as there is a

call for heat, the safety control can be

reset, which starts another purge

cycle and try for ignition.

Once ignited, as additional heat is

required, the combustion 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

and be locked out until reset at the

unit mounted Human Interface panel.

As the heating requirement is

satisfied, the HEAT module will

modulate the combustion air damper

closed 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 individual stages of electric heat

will be sequenced on the zone

demand. The number of available

stages will depend on the unit size

and heat capacity selected.

Hot Water or Steam

On units with hot water or steam

heating, the supply air temperature

can be controlled to a heating

setpoint during the Occupied mode.

The supply air temperature heating

setpoint and deadband are user-

defined at the Human Interface Panel.

VAV Occupied heating on hot water

and steam heat units is enabled by

closing a field-supplied switch or

contacts connected to an changeover

input on the RTM.

Supply Air Setpoint Reset

Supply air setpoint 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 setpoint

reset adjustment is available from

the Human Interface Panel for supply

air heating and supply air cooling

control.

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 primary cooling, thus

savings in mechanical cooling kw,

but an 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

– amount of temperature reset

Zone reset is applied to the zone(s) in

a building that tend to over cool or

RT-PRC031-EN 13

Controls Variable Air Volume (VAV) Only

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.

Modulating gas, electric, hot water

and steam heat units only—When

supply air temperature falls below

the supply air temperature deadband

low end, the heat valve will be

modulated to maintain the set

minimum supply air temperature.

Zone Temperature

Control

Unoccupied Zone Heating and

Cooling

During Unoccupied mode, the unit is

operated as a CV unit. Inlet guide

vanes are driven full open, VFDs

operate at 100%, and VAV boxes are

driven full open. The unit controls

zone temperature within the

Unoccupied zone cooling and

heating (heating units only)

setpoints.

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.

Fresh Air Measurement

Trane air quality (TRAQ™) fresh air

measurement damper system utilizes

velocity pressure sensing rings.

Based on unit design CFM, the

ventilation control module (VCM)

monitors and controls the quantity of

fresh outside air entering the unit.

The outside airflow can be calibrated

to accommodate for altitude.

a. An optional temperature

sensor may be connected to

the ventilation control

module to enable it to control

a field-installed pre-heater.

b. An optional CO2 sensor may

be connected to the

ventilation control module to

control fresh air based on

CO2 Demand Control

Ventilation (DCV).

Outside Air CFM

Compensation

As the supply fan (IGV or VFD)

modulates, this function

proportionally adjusts the

economizer minimum position to

compensate for the change in total

airflow, in order to maintain a

constant percent of outside air. The

modified economizer minimum

position is computed as a linear

function, based on IGV or VFD

position, given the two endpoints,

a. Minimum Position with IGV/

VFD @ 0%

b. Minimum Position with IGV/

VFD @ 100%

which are user adjustable at the

Human Interface Panel.

14 RT-PRC031-EN

CV Units Only

Occupied Zone

Temperature Control

Cooling/Economizer

During Occupied cooling mode, the

economizer (if provided) and

mechanical cooling are used to

control zone temperature. The zone

temperature cooling setpoint is user-

defined at the Human Interface Panel

or from the BAS/Network.

If the conditions 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 if

required the hydronic valve will be

modulated to maintain supply air

temperature setpoint.

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: 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.

At outdoor air conditions

above the enthalpy control

setting, mechanical cooling

only is used and the outdoor

air dampers remain at

minimum position. For

comparative enthalpy

economizer control, outdoor

air enthalpy must be below

the enthalpy of the return air.

If the unit does not include an

economizer, primary cooling only is

used to satisfy cooling requirements.

The outdoor air dampers may be set

for a maximum of 25 percent

outdoor air, through the unit

mounted Human Interface Panel or a

signal from the BAS/network, if the

air handler is equipped with 0 to 25

percent motorized fresh air dampers.

A temperature sensor, located on the

entering air side of the chilled water

coil, will send a signal to the

hydronic valve to drive it full open

when a potential freeze condition is

detected. The supply fan is then

turned off and the outside air

damper is closed.

Heating

Gas Heating: Two-Stage

Upon a call for heating, the HEAT

module 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 60 second pre-

purge cycle is executed. Then the

ignition sequence takes place.

If ignition is not proven, the safety

control locks out and must be

manually reset. As long as there is a

call for heat, the safety control can

be reset, which starts another purge

cycle and try for ignition.

As additional heat is required, the

HEAT module 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. On the low heat and medium

heat for all units, after a one minute

delay, plus another 60 second pre-

purge cycle the ignition cycle begins.

On all other heat sizes the heating

section will be shutdown and locked

out until manually reset at the

ignition module and unit mounted

Human Inferface Panel after the first

shutdown due to flame instability.

As the heating requirement is

satisfied, the HEAT module 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.

Gas Heating: Modulating Gas

Upon a call for heating, the HEAT

module closes the heating contacts,

beginning the firing sequence. First,

the heat exchanger combustion

blower begins operation. Upon

positive proving of combustion

airflow, a pre-purge cycle is

executed. Then the ignition

sequence takes place.

If ignition is not proven, the safety

control locks out and must be

manually reset. As long as there is a

call for heat, the safety control can

be reset, which starts another purge

cycle and try for ignition.

Once ignited, as additional heat is

required, the combustion 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

and be blocked out until reset at the

unit mounted Human Interface

panel.

As the heating requirement is

satisfied, the HEAT module will

modulate the combustion air

damper closed, 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.

Controls Constant Volume (CV) Only

RT-PRC031-EN 15

Controls Constant Volume (CV) Only

Electric Heating

The individual stages of electric heat

will be sequenced on the zone

demand. The number of available

stages will depend on the unit size

and heat capacity selected.

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 fresh air damper is closed.

Supply Air Tempering

For staged gas and electric heat units

in the occupied Heating 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 turned off if the supply air

temperature rises to 10°F above the

Occupied zone heating temperature

setpoint.

On units with hot water or steam

heating, if the supply air temperature

drops below 48°F, the heating valve

is modulated to maintain 50°F supply

air temperature with a 4°F deadband.

Auto Changeover

When the System Mode is “Auto,” the

mode will change to cooling or

heating as necessary to satisfy the

zone cooling and heating setpoints.

The zone cooling and heating

setpoints can be as close as 2°F

apart.

Unoccupied Zone

Temperature Control

Cooling and Heating

Cooling and/or heating modes can be

selected to maintain Unoccupied

zone temperature setpoints. For

Unoccupied periods, heating,

economizer operation or primary

cooling operation can be selectively

locked out at the Human Interface

Panels.

16 RT-PRC031-EN

Common to VAV and

CV Units

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, space pressure

deadband and exhaust enable point.

As the economizer opens, the

building pressure rises and once

above the exhaust enable point,

enables the exhaust fan and

dampers or exhaust VFD. The

exhaust dampers or VFD then

modulate to maintain space pressure

within the deadband.

Morning Warm-up Options

This feature may be enabled on all

types of factory installed heat units

as well as cooling only units

configured as “External Heat” (for

example, VAV boxes with reheat).

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.

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

occupied mode.

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 the MWU setpoint is reached or

for 60 minutes, then the unit

switches to Occupied mode.

A control algorithm is used to

increase or decrease the amount of

heat in order to achieve the MWU

zone temperature setpoint.

Note: When using the Morning

Warm-up option in a VAV

heating/cooling air handler,

airflow must be maintained

through the air handler unit.

This can be accomplished by

electrically tying the VAV

boxes to the VAV box output

relay contacts on the Rooftop

Module (RTM) or by using

changeover thermostats.

Either of these methods will

assure adequate airflow

through the unit and

satisfactory heating of the

building.

Emergency Override

module is installed, the user can

initiate from the Trane Tracer

Summit or 3rd party BAS one of five

fan will shut off, and the fresh air

dampers will close.

Steam and Hot Water Coil -

Freeze Avoidance

Freeze Avoidance is a feature which

helps prevent freezing of steam or

hot water heat coils during periods of

unit inactivity and low ambient

temperatures. Whenever the unit

supply fan is off, the outdoor air

temperature is monitored. If the

temperature falls below a

predetermined value, the heating

valve is opened to a position selected

at the unit mounted Human Interface

to allow a minimum amount of

steam or hot water to flow through

the coil and avoid freezing

conditions.

Applications with Chilled

Occupied/Unoccupied

Switching

Description - 3 ways to switch

Occupied/Unoccupied:

1. Night Setback (NSB) Panel

2. Field-supplied contact closure

(hard wired binary input to RTM)

3. TRACER (or 3rd Party BAS with

LCI module)

Night Setback Sensors

Trane's night setback sensors are

programmable with a time clock

function that provides

communication to the air handler

unit through a 2-wire

communications link. The desired

transition times are programmed at

the night setback sensor and

communicated to the air handler.

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 air

handler heating/cooling (if enabled)

20 RT-PRC031-EN

Controls VAV and CV

function and the supply fan. The air

handler 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 air

handler, airflow must be maintained

through the air handler unit. This can

be accomplished by electrically tying

the VAV boxes to the VAV Box output

relay contacts on the Rooftop Module

(RTM) or by using changeover

thermostats. Either of these methods

will assure adequate airflow through

the unit and satisfactory temperature

control of the building.

Occupied/Unoccupied input

on the RTM

This input accepts a field supplied

switch or contacts closure such as a

time clock.

Trane Tracer™ or BAS System

The Trane Tracer System or a 3rd

party BAS (with LCI module) can

control the Occupied/Unoccupied

status of the air handler.

Timed Override Activation -

ICS

This function is operational when the

RTM is selected as the Zone

Temperature Sensor source 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 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.

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 outdoor air temperature

and humidity to the economizer

enthalpy control setpoint. If outdoor

air 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 outdoor temperature

comparing it to the economizer

control temperature setpoint. If the

outdoor 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.

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.

High Duct Temp Thermostat

Two manual reset, high temperature

limit thermostats are provided. One

is located in the discharge section of

the unit set at 240ºF and the other in

the return air section of the unit set at

135ºF. If either setpoint is reached, the

air handler unit is shut down.

CO2 Control - Demand Control

Ventilation (DCV)

A ventilation reset function that

provides the necessary ventilation for

occupants and reduces energy

consumption by minimizing the

outdoor air damper position (or the

OA flow setpoint with TRAQs) below

the Building Design Minimum, while

still meeting the ASHRAE Std 62.1-

2004 ventilation requirements.

If the space CO2 level is greater than

or equal to the CO2 Design Setpoint,

the outdoor air damper will open to

the Design Min Outdoor Air Damper

(or OA Flow) Setpoint. If there is a call

for economizer cooling, the outdoor

air damper may be opened further to

satisfy the cooling request.

If the space CO2 level is less than or

equal to the CO2 Minimum Setpoint,

the outdoor air damper will close to

the DCV Minimum Outdoor Air

Damper (or OA Flow) Setpoint.

RT-PRC031-EN 21

Controls VAV and CV

If there is a call for economizer

cooling, the outdoor air damper may

be opened further to satisfy the

cooling request.

If the space CO2 level is greater than

the CO2 Minimum Setpoint and less

than the CO2 Design Setpoint, the

outdoor air damper position is (or OA

flow) modulated proportionally to the

Space CO2 level relative to a point

between the CO2 Min Setpoint and

the CO2 Design Setpoint. If there is a

call for economizer cooling, the

outdoor air damper may be opened

further to satisfy the cooling request.

Humidification Control

A relay output is provided to control

an externally connected, field

supplied humidifier. Logic is

provided for Occupied and

Return Fan Control

A return fan reduces the load on the

supply fan motor or can allow a unit

to operate at a higher static pressure.

The return fan VFD is modulated

LonTalk® Building

Automation System

The LonTalk Communication

Interface for IntelliPak II (LCI-I)

controller expands communications

from the unit UCM network to a

Trane Tracer Summit or a 3rd party

building automation system, utilizing

LonTalk, and allows external setpoint

and configuration adjustment and

monitoring of status and diagnostics.

The LCI-I utilizes an FTT-10A Free

Topology transceiver, which supports

non-polarity sensitive, free topology

wiring, which allows the system

installer to utilize star, bus, and loop

architectures.This controller works in

standalone mode, peer-to-peer with

one or more other units, or when

connected to a Trane Tracer Summit

or a 3rd party building automation

system that supports LonTalk. The

LCI-I controller is available as a

factory or field-installed kit.

Twinning

Twinning is a Master Unit and one, or

more, similarly configured Slave

Unit(s) operating cooperatively, as a

group, to provide higher capacity

and/or redundancy at partial capacity.

Twinning requires an LCI module

installed in each unit and is

accomplished by binding variables

between unit communication

modules, communicating common

setpoints and conditions

(temperatures, pressures, fan

speeds, damper positions,

occupancy, states, etc.) and allowing

each unit to run independent

algorithms.

Twinned units must share a common

supply and return duct network.

Twinned units operate:

a. as part of a Trane ICS™

installation, with Tracer

Summit

b. on an interoperable project

with a 3rd party LonTalk

c. as an independent group

(bound via Rover® or 3rd

party tool).

22 RT-PRC031-EN

Exhaust/Return

Fan 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 under-pressurization 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.

The reason for applying either a

return, or exhaust fan is to control

building pressure. The Trane 100

percent modulating exhaust system

with Statitrac is an excellent choice

for controlling building pressure in

the majority of applications.

For more demanding applications,

Trane's 100 percent modulating

return fan system with Statitrac is an

excellent choice for systems with

high return static pressure losses, or

duct returns. Both systems employ

direct digital control technology to

maintain building pressure. Either

return or exhaust fan systems with

Statitrac may be used on any air

handler application that has an

outdoor air economizer.

A building may have all or part of its

exhaust system in the air handler

unit. Often, a building provides

exhaust external to the air handling

equipment. This external exhaust

must be considered when selecting

the air handler exhaust system.

With an exhaust fan system, the

supply fan motor and drives must be

sized to overcome the total system

static pressure, including return

losses, and pull return air back to the

unit 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 fan

systems.

In a return fan system, the return fan

is in series with the supply fan, and

operates continuously whenever the

supply fan is operating to maintain

return air volume. The supply fan

motor and drives are sized to deliver

the design CFM based on internal

and discharge static pressure losses

only.

The return fan motor and drives are

sized to pull the return CFM back to

the unit based on return duct static.

Therefore, with a return fan system,

the supply fan ordinarily requires

less horsepower than a system with

an exhaust fan

practices

Application

Recommendations

100 Percent Modulating Exhaust

with Statitrac Control, Constant

Volume and VAV Units

For both CV and VAV air handlers,

the 100 percent modulating exhaust

discharge dampers (or VFD) are

modulated in response to building

pressure. A differential pressure

control system, Statitrac, uses a

differential pressure transducer to

compare indoor building pressure to

atmospheric pressure.

The FC exhaust fan is turned on

when required to lower building

static pressure to setpoint. The

Statitrac control system then

modulates the discharge dampers

(or VFD) to control the building

pressure to within the adjustable,

specified deadband that is set at the

Human Interface Panel.

Economizer and return air dampers

are modulated independent of the

exhaust dampers (or VFD) based on

ventilation control and economizer

cooling requests.

Advantages:

• The exhaust fan runs only when

needed to lower building static

pressure.

• Statitrac compensates for

pressure variations within the

building from remote exhaust

fans and makeup air units.

• The exhaust fan discharges in a

single direction resulting in

more efficient fan operation

compared to return fan systems.

• When discharge dampers are

utilized to modulate the exhaust

airflow, the exhaust fan may be

running unloaded whenever the

economizer dampers are less

than 100 percent open.

Applications Considerations

RT-PRC031-EN 23

Applications Considerations

The Trane 100 percent modulating

exhaust system with Statitrac

provides efficient control of building

pressure in most applications 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.

100 Percent Modulating Exhaust

System without Statitrac,

Constant Volume Units Only

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.

Advantages:

• The exhaust fan runs only when

the economizer reaches the

desired exhaust enable point.

• Exhaust dampers are modulated

based on the economizer

position.

• The exhaust fan discharges in a

single direction resulting in more

efficient fan operation compared

to return fan systems.

• When discharge dampers are

utilized to modulate the exhaust

airflow, the exhaust fan may be

running unloaded whenever the

economizer dampers are less

than 100 percent open.

The Trane 100 percent modulating

exhaust system provides excellent

linear control of building exhaust in

most applications where maintaining

building pressure is not important.

100 Percent Modulating

Return Fan Systems with

Statitrac™ Control, Constant

Volume and VAV units

For both CV and VAV applications,

the IntelliPak II air handler offers 100

percent modulating return fan

systems. A differential pressure

control system, Statitrac, uses a

differential pressure transducer to

compare indoor building pressure to

atmospheric pressure. The return fan

exhaust dampers are modulated,

based on space pressure, to control

the building pressure to within the

adjustable, specified deadband that

is set at the Human Interface Panel. A

VFD modulates the return fan speed

based on return duct static pressure.

Economizer and return air dampers

are modulated independent of the

exhaust dampers based on

ventilation control and economizer

cooling requests.

Advantages:

• The return fan operates

independently of the supply fan

to provide proper balance

throughout the airflow envelope.

• Statitrac compensates for

pressure variations within the

building from remote exhaust

fans and makeup air units.

• The return fan acts as both

exhaust and return fan based on

operation requirements.

The Trane 100 percent modulating

return system with Statitrac provides

efficient control of building pressure

in applications with higher return

duct static pressure and applications

requiring duct returns.

Exhaust discharge dampers are

controlled directly from building

pressure, return fan VFD is controlled

from return static pressure, and

return/economizer dampers are

controlled based on ventilation

control and economizer cooling

requests. 100 Percent Modulating

Return Fan without Statitrac™

Control, Constant Volume Units Only

The exhaust discharge dampers are

modulated in response to building

pressure. The return fan runs

continuously while the supply fan is

energized.

Economizer and return air dampers

are modulated independent of the

exhaust dampers based on

ventilation control, and economizer

cooling requests.

Advantages:

• The exhaust dampers are

modulated as needed through a

space pressure sensor input to

maintain building pressure.

• The return fan discharges in two

directions, thereby balancing

exhaust and unit return air

volumes.

Supply and Return Airflow

Configurations

The typical air handler installation

has both the supply and return air

paths routed through the roof curb

and building roof. However, many air

handler installations require

horizontal supply and/or return from

the air handler because of a

building's unique design or for

acoustic considerations.

With IntelliPak II, there are several

ways to accomplish horizontal

supply, see Ta bl e 1, p. 24 and/or

return, see Ta bl e 2, p . 24 .

Applications Considerations

When using an IntelliPak II Air

Handler for horizontal supply and/or

return, an additional pressure drop

must be added to the supply external

static to account for the 90 degree

turn the air is making. This additional

pressure drop depends on airflow

and air handler size, but a range of

0.10 inches to 0.30 inches can be

expected. The openings on the air

handler all have a one inch lip around

the perimeter to facilitate ductwork

attachment.

Corrosive Atmospheres

Trane's IntelliPak II Air Handlers 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.

Because copper is more resistant to

corrosion than aluminum, coil life

expectancy is greatly increased.

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 air

handler can be used as part of a

ventilation override system. Several

types of sequences can be easily

done when exhaust fans are a part of

the air handling system.

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 II Air

Handlers. For convenience, the

sequences are factory preset but are

fully field edited 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/Return Fan - on/off

• Exhaust Dampers - open/closed

• Economizer dampers - open/

closed

• Heat - off/controlling (output for)

VAV Boxes - open/controlling

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 Ventilation

Override Module (VOM) page 17 in

the Control section of this catalog for

more details on each override

sequence.

Natural Gas Heating

Considerations

Trane uses heavy gauge 304 L

stainless steel throughout the

construction of its natural gas drum

and tube heat exchangers for the

IntelliPak II product. These heat

exchangers can be applied with

confidence, particularly with full

modulation control, when mixed air

temperatures are below 50°F, and low

ambient temperatures can cause

condensation to form on the heat

exchanger. IntelliPak II natural gas

heat exchangers are not

recommended for applications with

mixed air conditions entering the

heat exchanger below 30°F to insure

adequate leaving air heating

temperature.

For airflow limitations and

temperature rise across the heat

exchanger information, see Ta bl e 27,

p. 70.

Acoustical Considerations

The ideal time to make provisions to

reduce sound transmission to the

space is during the project design

phase. Proper placement of air

handler equipment is critical to

reducing transmitted sound levels to

the building. The most economical

means of avoiding an acoustical

problem is to place any air handler

equipment away from acoustically

critical areas. If possible, air handling

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

Locate the unit's center of gravity

close to or over a column or main

support beam to minimize roof

deflection and vibratory noise.

2

If the roof structure is very light, roof

joists should be replaced by a

structural shape in the critical areas

described above.

3

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

26 RT-PRC031-EN

Applications Considerations

will help reduce sound transmission.

The ASHRAE publication "A Practical

Guide to Noise and Vibration Control

for HVAC Systems" also provides

valuable information.

There are several other sources of

unit sound, i.e., supply fan, exhaust/

return fans, and aerodynamic noise

generated at the duct fittings. Refer

to the ASHRAE Applications

Handbook, Chapter 47, 2003 edition

for guidelines for minimizing the

generation of aerodynamic noise

associated with duct fittings. A good

source of information on general

acoustical considerations for air

handlers is the 2000 ASHRAE Journal

article titled, "Controlling Noise from

Large Rooftop Units".

The Trane Acoustic Program (TAP)

allows complete modeling of air

handler acoustical installation

parameters. The software models

airborne sound from supply and

return ducts, as well as duct breakout

and roof transmission sound, so that

the designer can identify potential

sound problems and make design

alterations before equipment

installation. Output of the program

shows the resulting NC (or RC) level

for any point in the occupied space.

TAP is also capable of modeling the

effect of outdoor sound on the

surrounding area. This program is

available from Trane's Customer

Direct Service NetworkTM (C.D.S.),

ask your local Trane representative

for additional information on this

program.

Clearance Requirements

The recommended clearances

identified in Figure 31, p. 85 should

be maintained to assure adequate

service capability, maximum capacity

and peak operating efficiency. 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 coils?

• Do the clearances available allow

for proper outside air intake and

exhaust air removal?

• If screening around the unit is

being used, is there a possibility

of air recirculation from the

exhaust to the outside air 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,

see Figure 15, p. 26, 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.

Applications Considerations

Duct Design

It is important to note that the rated

capacities of the air handler can be

met only if the air handler 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 air handler

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

air handler outlet, the loss of capacity

and static pressure may be reduced

through the use of guide vanes and

proper direction of the bend in the

elbow. The high velocity side of the

air handler outlet should be directed

at the outside radius of the elbow

rather than the inside as illustrated in

Figure 16, p. 27.

Figure 16. Duct Design

IMPROPER

PROPER

Protecting Hydronic Coils

From Freezing

Taking in outdoor air to satisfy

Standard 62’s ventilation

requirement increases the likelihood

of air stratification. If a layer of air

below freezing moves through the air

handler, it can damage unprotected

hydronic cooling and heating coils.

When a dangerously low air

temperature is detected by the low-

limit thermostat on the entering-air

side of the coil, it will trip. That

triggers the water valve to fully open,

the supply fan to stop, the outdoor

air damper to close and ultimately

degrades the building’s indoor air

quality.

Two options that can be

implemented to continue taking in

outdoor air and avoid coil damage or

tripping the low-limit thermostat

include:

• Draining the coils

• Adding glycol to the cooling

system water to lower its

freezing point

External Piping Enclosure

Space inside the piping enclosure

limits the ability to house control

valves and actuators along with coil

supply and return piping.

Cooling Capacity Selection:

Step 1 - Coil and Fan

Selection

A summation of the peak cooling

load and the outside air ventilation

load shows: 980 MBH + 154.0 MBH =

1134.0 MBH required unit capacity.

The supply fan air flow requirement

is 36,000 cfm.

From Tab le 10, p. 3 9 , a 4 row W coil

with 144 fpf (fins per foot) and no

turbulators at 80 DB/67 WB and

36000 supply air cfm has a total

cooling capacity of 1336 MBH and

sensible cooling capacity of 969

MBH. With chilled water coil capacity

data at 80 DB/67 WB only, TOPSS is

required for an accurate selection at

other conditions. TOPSS is also

required to select the correct water

control valve for proper flow control,

in this case a 2 ½ "or 3" valve.

Ta b l e 3, p . 34 - General Data shows

that air handler "C" can provide

36000 total supply CFM.

Thus air handler "C" with a 4 row 144

fpf W coil having no turbulators at

45°F entering water and a 10°F rise

with a 2 ½" valve is selected. The coil

water flow rate is 266 GPM and

water side pressure drop is 13.7 ft of

water.

Step 2 - Cooling Coil Entering

Conditions

Mixed air dry bulb temperature

determination:

Using the minimum percent of OA

(3600 CFM ÷ 36000 CFM = 10

percent), determine the mixture dry

bulb to the cooling coil.

RADB + % OA (OADB - RADB) = 78 +

(0.10) (95 - 78) = 78 + 1.5 = 79.5°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 air handler casing

"C" with a 4 row 144 fpf W coil and

no turbulators, the supply fan BHP

can be calculated.

The supply fan motor heat gain must

be considered in final determination

of unit capacity.

Supply Air Fan

Determine unit total static pressure

at design supply CFM:

Using total of 36000 CFM and total

static pressure of 4.0 inches, enter

Tabl e 17, p. 4 8 . The table shows 40.4

BHP with 1097 rpm required for the

36" supply fan.

From Figure 17, p. 30 supply fan

motor heat gain = 109.0 MBH, or

109.0 MBH x 1000 ÷ ( 36000 CFM x

1.085 ) = 2.8°F supply fan motor heat

Step 4 - Determine Total

Required Cooling Capacity

Required capacity = Total peak load +

OA load + supply air fan motor heat

Required capacity = 980.0 + 154.0 +

109.0 = 1243.0 MBH

Step 5 - Determine Unit

Capacity

The coil entering air conditions of

79.5 DB/66.1 WB are close to the

capacity data table at 80 DB/67 WB

used for the original selection. The

unit capacity with the 4 row 144 fpf

W coil with no turbulators at 45°F

entering water a 10°F rise, 36000 cfm

supply air flow and 10% outside air

Selection Procedure

at 95°F is approximatly 1336 MBH

total cooling and 969 MBH sensible

cooling capacity.

Step 6 - Determine Leaving Air

Temperature

Unit sensible heat capacity corrected

for supply air fan motor heat = 969

MBH Sensible - 109.0 MBH Motor

Heat = 860 MBH.

Supply air dry bulb temperature

difference =

Sensible MBH X 1000/1.085 x Supply

CFM

Sensible Btu = 860 MBH x 1000 ÷

(1.085 x 36000 CFM) = 22°F

Supply air dry bulb = 79.5 DB - 22 =

57.5°F Leaving the cooling coil

Supply air wet bulb temperature

difference = (need in RTU catalog

too)

Total MBH x 1000 ÷ 4.5 x Supply CFM

=

Unit enthalpy difference = 1336 MBH

x 1000 ÷ (4.5 x 36000 CFM) = 8.25

Btu/lb.

Leaving enthalpy = h (ent WB) - h

(diff). From Tab le 6 , p . 3 7, p. 40 h (ent

WB) =

30.9 Btu/lb.

Leaving enthalpy = 30.9 Btu/lb. - 8.25

Btu/lb. = 22.65 Btu/lb.

Supply air wet bulb = 54.0 Leaving

the cooling coil.

Leaving air temperature = 57.5 DB/

54.0 WB

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 = 109000 Btu ÷

(1.085 x 36000 CFM) = 2.8°F

Air temperature entering heating

module = 63.0 + 2.8 = 65.8°F

Step 2 - Determine Total

Winter Heating Load

Total winter heating load = peak

heating load + ventilation load -

supply fan motor heat = 720 + 288.6 -

109.0 = 899.6 MBH

Electric Heating System

Unit operating on 460/60/3 power

supply.

From Table 29, p. 70, kw may be

selected for a nominal 105 ton air

handler "C" unit operating at 460-volt

power. The 265 kw heat module

(904.4 MBH) will satisfy the winter

heating load of 899.6 MBH.

Table 28, p. 70 shows an air

temperature rise of 23.2°F for 36000

CFM through the 265 kw heat

module.

Unit supply temperature at design

heating conditions = mixed air

temperature + air temperature rise =

65.8°F + 23.2°F = 89.0°F.

Gas Heating System (Natural

Gas)

From Tab le 2 7, p . 7 0 select the high

heat module (1440 MBH output) to

satisfy winter heating load of 899.6

MBH at unit CFM.

Ta b l e 27, p. 7 0 also shows an air

temperature rise of 37.0°F for 36000

CFM through the heating module.

Unit supply temperature at design

heating conditions = mixed air

temperature + air temperature rise =

65.8°F + 37.0°F = 102.8°F.

Hot Water Heating System

Using a hot water supply

temperature of 190°F and an entering

coil temperature of 65.8°F.

Subtract the mixed air temperature

from the hot water temperature to

determine the ITD (initial

temperature difference).

ITD = 190°F - 65.8°F = 124.2°F.

Divide the winter heating load by ITD

= 1008.6 MBH ÷ 124.2°F = 8.12 Q/

ITD.

From Table 30, p. 71, select the low

heat module. By interpolation, a Q/

ITD of 8.12 can be obtained at a gpm

of 41. Water pressure drop at 41 gpm

is 0.34 ft. of water.

Heat module temperature rise is

determined by:

Total Btu = 1.085 x CFM x Air

temperature rise, °F 1008600 / 1.085 /

36000 = 25.8°F

Unit supply air temperature = mixed

air temperature + air temperature

rise = 65. 8 + 25.8 = 91.6°F.

Steam Heating System

Using a 15 psig steam supply. From

Table 31, p. 71, the saturated

temperature steam is 250°F. Subtract

mixed air temperature from the

steam temperature to determine ITD.

ITD = 250°F - 65.8°F = 184.2°F.

Divide winter heating load by ITD =

1008.6 MBH ÷ 184.2°F = 5.48 Q/ITD.

Table 31, p. 71, select the low heat

module. The low heat module at

36000 cfm has a Q/ITD = 7.44

Heat module capacity, Q = ITD x Q/

ITD = 185°F x 7.44Q/ITD = 1376 MBH

Heat module air temperature rise is

determined by:

Total Btu = 1.085 x CFM x Air

temperature rise, °F 1376000 / 1.085 /

36000 = 35.2°F

Unit supply temperature at design

conditions = mixed air temperature +

air temperature rise = 65.8°F + 35.2°F

= 100.1°F.

Air Delivery Procedure

Supply fan performance tables

include internal resistance of air

handler.

For total static pressure

determination, system external static

must be added to appropriate

component static pressure drop

cooling coil, filters, optional

economizer, optional exhaust fan,

optional heating system, optional

cooling only extended casing).

Supply Fan Motor Sizing

The supply fan motor selected in the

cooling capacity determination was

40.4 BHP and 1097 RPM. Thus, a 40

HP supply fan motor is selected.

Enter Table 39, p. 77 to select the

proper drive. For anair handler "C"

with 40 HP motor, a drive letter A -

1100 RPM is selected.

30 RT-PRC031-EN

Selection Procedure

Exhaust Fan Motor Sizing

The exhaust/return fan is selected

based on total return system

negative static pressure and exhaust

fan CFM. Return system negative

static includes return duct static, and

any other job site applicable static

pressure drop.

Return duct static pressure = 0.30

inches.

Total return system negative static

pressure = 0.30 inches.

Exhaust fan CFM = 36000 CFM

From Table 39, p. 77 the required

BHP is 21.44 BHP at 400 RPM. Thus,

the exhaust fan motor selected is 25

HP.

To select a drive, enter Ta bl e 3 7, p. 75

for a 25 HP motor and air handler

"C". Drive selection number 4 - 400

RPM.

Return Fan Motor Sizing

The same static pressure and CFM

considerations must be taken for

return fan size, horsepower, and

drive selection as are required for

exhaust fan sizing. However, since

the return fan runs continuously the

sensible heat generated by the return

fan motor must be included in the

entering evaporator coil mixed air

temperature equation.

In this selection, if the return motor

BHP is equal to the exhaust motor

BHP, 21.44 BHP = 58.1 MBH x 1000÷

(1.085 x 36000 Return CFM) = 1.5°F

added to the return air temperature.

Where altitudes are significantly

above sea level, use Table 6, p. 37,

Table 7, p. 37 and Ta bl e 8 , p . 37 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 air handler performance tables

and curves of this catalog are based

on standard air (.075 lbs/ft). If the

airflow requirements are at other

than standard conditions (sea level),

an air density correction is needed to

project accurate unit performance.

Figure 18, p. 37 shows the air density

ratio at various temperatures and

elevations.

The procedure to use when selecting

a supply or exhaust/return fan at

elevations and

temperatures other than standard is

as follows:

1. First, determine the air density

ratio using Figure 18, p. 37.

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 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 an air handler"C" that is to

deliver 32000 actual CFM at 3-inches

total static pressure (tsp), 55°F

leaving air temperature, at an

elevation of 5000 ft.

1. From Figure 18, p. 37, the air

density ratio is 0.86.

2. Tsp = 3.0-inches / 0.86 = 3.49

inches tsp.

3. From fan performance Tab l e 17,

p. 48 air handler"C" (without inlet

vanes) will deliver 32000 CFM at

3.49 inches TSP at 997 RPM and

30.27 BHP.

4. The RPM is correct as selected -

997 RPM.

5. BHP = 30.27 x 0.86 = 26.3 BHP

actual.

Cooling coil MBH should be

calculated at standard and then

converted to actual using the

correction factors in Tabl e 6 , p . 3 7 ,

Table 7, p. 37, Tab le 8, p. 37 . 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

Ta b l e 8, p . 37 before calculating the

heating supply air temperature.

Notes:

1. Supply fan performance table includes internal resistance of air handler. For total

static pressure determination, system external static pressure must be added to

appropriate component sp drops (chilled water coil, filters, optional economizer,

optional heating system).

2. Maximum SP leaving the air handler is 5.5" H20 positive.

Notes:

1. Supply fan performance table includes internal resistance of air handler. For total static pressure determination, system external

static pressure must be added to appropriate component sp drops (chilled water coil, filters, optional economizer, optional

heating system).

2. Maximum SP leaving the air handler is 5.5" H20 positive.

(i) Outlined area indicates nonstandard BHP or RPM selections. Contact a local Trane representative for more information.

Notes:

1. Supply fan performance table includes internal resistance of air handler. For total static pressure determination, system external

static pressure must be added to appropriate component sp drops (chilled water coil, filters, optional economizer, optional

heating system).

2. Maximum SP leaving the air handler is 5.5" H20 positive.

(i) Outlined area indicates nonstandard BHP or RPM selections. Contact a local Trane representative for more information.

Notes:

1. Supply fan performance table includes internal resistance of air handler. For total static pressure determination, system external

static pressure must be added to appropriate component sp drops (chilled water coil, filters, optional economizer, optional

heating system).

2. Maximum SP leaving the air handler is 5.5" H20 positive.

(i) Outlined area indicates nonstandard BHP or RPM selections. Contact a local Trane representative for more information.

Notes:

1. Supply fan performance table includes internal resistance of air handler. For total static pressure determination, system external

static pressure must be added to appropriate component sp drops (chilled water coil, filters, optional economizer, optional

heating system).

2. Maximum SP leaving the air handler is 5.5" H20 positive.

(i) Outlined area indicates nonstandard BHP or RPM selections. Contact a local Trane representative for more information.

Electrical Service Sizing

To correctly size electrical service

wiring for a unit, find the appropriate

calculations listed below. Each type

of unit has its own set of calculations

for MCA (Minimum Circuit

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 unit

type.

Note: Set 1 is for cooling only and

cooling with gas heat units,

and set 2 is for cooling with

electric heat units.

Load Definitions: (To determine load

values, see the Electrical Service

Sizing Data Tables on the following

page.)

LOAD1 = CURRENT OF THE

LARGEST 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 with Gas Heat Air

Handling 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 select the

lowest standard maximum

fuse size which is equal to or

larger than the MCA,

provided the selected 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 select the RDE value to

equal the MOP value.

Set 2. Cooling with Electric Heat

To arrive at the correct MCA, MOP,

and RDE values for these units, two

sets of calculations must be

performed. First calculate the MCA,

MOP, and RDE values as if the unit

was in cooling mode (use the

equations given in Set 1). Then

calculate the MCA, MOP, and RDE

values as if the unit were in the

heating mode as follows.

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 select the

lowest standard maximum

fuse size which is equal to or

larger than the MCA,

provided the selected 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 select the RDE value to

equal the MOP value.

GENERAL NOTE

Note: The selected MOP value is

stamped in the MOP field on

the nameplate.

are available for all units.

Fan Options

• Standard CFM supply exhaust/

return fans—Available to meet

standard airflow application

needs.

• Low CFM exhaust fans—

Available to meet low leaving air

temperature requirements.

Power Supply

Air Handlers are available with 460

or 575 voltage, 3 phase 60 hertz

power supply.

Exhaust

• No Exhaust—Air Handlers can

be built for makeup air

applications with no exhaust.

Relief opening is sealed

watertight.

• 100 Percent Modulating Exhaust

Fan—A double width, double

inlet forward-curved fan can

exhaust up to 100 percent

supply air. The fan operates

when economizer damper is

open greater than minimum

position. Discharge dampers at

fan outlet modulate in response

to economizer damper position

on Constant Volume (CV) air

handlers.

• 100 Percent Modulating Exhaust

Fan with Statitrac™ Control—

For both CV and Variable Air

Volume (VAV) air handlers, the

100 percent modulating exhaust

discharge dampers are

modulated in response to

building pressure. A differential

pressure control system,

Statitrac, uses a differential

pressure transducer to compare

indoor building pressure to

atmospheric pressure. The FC

exhaust fan is turned on when

required to lower building static

pressure to setpoint. The

Statitrac control system then

modulates the discharge

dampers to control the building

pressure to within the

adjustable, specified deadband

that is set at the Human Interface

Panel.

• 100 Percent Modulating Exhaust

Fan with Statitrac Control and

Variable Frequency Drive—

Provided with all the necessary

controls to control/maintain

building space pressure through

a CV or VAV air handler. The

Variable Frequency Drive (VFD)

modulates the speed of the

exhaust fan motor in response

to building pressure. A

differential pressure control

system, Statitrac, uses a

differential pressure transducer

to compare indoor building

pressure to atmospheric

pressure. The 0-100%

modulating relief dampers

modulate in response to a signal

from the unit microprocessor,

based upon the space static

pressure, and causes the

damper to modulate open or

closed as required to maintain

the space pressure within the

deadband.

• 100 Percent Modulating Exhaust

Fan with Statitrac Control and

Variable Frequency Drive and

Bypass—Bypass control

provides full nominal airflow in

the event of drive failure.

Return

• 100 Percent Modulating Return

Fan—A single width plenum fan

with airfoil blade can relieve up

Options

RT-PRC031-EN 95

Options

to 100 percent supply air. The fan

operates in conjunction with the

supply fan. The relief damper

modulates in response to

economizer damper position on

Constant Volume air handlers.

• 100 Percent Modulating Return

Fan with Statitrac Control and

Variable Frequency Drive and

Bypass—Provided with all the

necessary controls to control/

maintain building space pressure

through a VAV air handler. The

Variable Frequency Drive (VFD)

modulates the speed of the

return fan motor in response to

return plenum pressure. A

differential pressure control

system, Statitrac, uses a

differential pressure transducer

to compare indoor building

pressure to atmospheric

pressure. The Statitrac control

system modulates the relief

dampers to control the building

pressure to within the

adjustable, specified deadband

that is set at the Human Interface

Panel.

• 100 Percent Modulating Return

Fan with Statitrac Control and

Variable Frequency drive and

Bypass—Bypass control

provides full nominal airflow in

the event of drive failure.
