FEATURES

All models are available with a wide variety of factory­mounted options such as stainless steel heat exchangers,
phase monitor, dirty filter switch, and coil guard to make them
suitable for almost every application.

All units are self-contained and assembled on full perimeter
base rails with holes in the four corners for overhead rigging.
Every unit is completely piped, wired, charged and tested at
the factory to simplify the field installation and to provide
years of dependable operation.

All models (including those with an economizer) are suitable
for either bottom or horizontal duct connections. Models with

factory installed power exhaust are suitable for bottom
duct connections only. For bottom duct, you remove the

sheet metal panels from the supply and return air openings
through the base of the unit. For horizontal duct, you replace
the supply and return air panels on the rear of the unit with a
side duct flange accessory.

All models are available with these “factory mounted” outdoor
air damper options:

• Single enthalpy economizer with or without power
exhaust

• BAS-ready economizer with or without power exhaust

• Motorized outdoor air damper

• Barometric Relief Damper

A fixed outdoor air intake assembly will be shipped in the
return air compartment of all units ordered without an econo­mizer or motorized outdoor air damper option. The assembly
includes a rain hood with a damper that can be set for 10, 15
or 25% outdoor air. With bottom duct connections, the intake
damper assembly should be mounted over the opening in the
return air panel. With horizontal ductwork, it should be
mounted on the return air duct.

All supply air blowers are equipped with a belt drive that can be
adjusted to meet the exact requirements of the job. A high
static drive option is available for applications with a higher
CFM and/or static pressure requirement. A variable air volume
(V AV) option using a variable frequency drive is available for
applications requiring a constant supply duct pressure. A differ­ential pressure transducer is used to monitor supply duct static
pressure and return a speed reference signal to the VFD to
control the output of the indoor blower motor.

All compressors include scroll compressors and internal pres­sure relief. Every refrigerant circuit includes an expansion
valve, a liquid line filter-drier, a discharge line high pressure
switch and a suction line with a freezestat and low pressure/
loss of charge switch to protect all system components. A hot
gas bypass option, consisting of an adjustable compressor
discharge bypass valve, is available for low cooling load
applications.

• Simplicity® Controls - Simplicity® control boards have
standardized a number of features previously available
only as options or by utilizing additional controls.

• Low Ambient - An integrated low-ambient control
allows all units to operate in the cooling mode down
to 0ºF outdoor ambient without additional assistance.
Optionally , the contro l board can be programmed to
lockout the compressors when the outdoor air tem­perature is low or when free cooling is available.

•

The Simplicity® control board used in this product will
effectively operate the cooling system down to 0°F
when this product is applied in a comfort cooling
application for people. An economizer is typically
included in this type of application. When applying this
product for process cooling applications (computer
rooms, switchgear, etc.), please reference applications
bulletin AE-011-07 or call the applications department
for Unitary Products @ 1-877-UPG-SERV for
guidance. Additional accessories may be needed for
stable operation at temperatures below 30°F.

• Anti-Short Cycle Protection - To aid compressor
life, an anti-short cycle delay is incorporated into the
standard controls. Compressor reliability is further
ensured by programmable minimum run times. For
testing, the anti short cycle delay can be temporarily
overridden with the push of a button.

• Lead-Lag - An integrated Lead-Lag option allows
equal run time hours on all compressors, thereby
extending the life of all compressors. This option is
selectable on the unit control board.

• Fan Delays - Fan on and fan off delays are fully pro­grammable. Furthermore, the heating and cooling
fan delay times are independent of one another. All
units are programmed with default values based
upon their configuration of cooling and heat.

• Safety Monitoring - The control board monitors the
high and low-pressure switches, the freezestats, the
gas valve, if applicable, and the temperature limit
switch on gas and electric heat units. The unit con­trol board will alarm on ignition failures, compressor
lockouts and repeated limit switch trips.

• Nuisance Trip Protection and Strikes - To prevent
nuisance trouble calls, the control board uses a
“three times, you’re out” philosophy. The high and
low-pressure switches and the freezestats must trip
three times within two hours before the unit control
board will lock out the associated compressor.

• On Board Diagnostics - Each alarm will energize a
trouble light on the thermostat, if so equipped, and
flash an alarm code on the control board LED. Each
high and low-pressure switch alarm as well as each
freezestat alarm has its own flash code. The control
board saves the five most recent alarms in memory,
and these alarms can be reviewed at any time.
Alarms and programmed values are retained
through the loss of power.

fort™, Novar

®

, Honeywell, Johnson, York Commercial

Comfort System (YCCS) and CPC.

F A CTORY-INSTALLED OPTIONS

• SINGLE INPUT ELECTRONIC ENTHALPY ECONO-

MIZERS - Includes a slide-in / plug-in damper assembly

with fully modulating spring-return motor actuator capa­ble of introducing up to 100% outdoor air with nominal
1% leakage type dampers.

The enthalpy system contains one sensor that monitors
the outdoor air and determines when the air is cool
enough and dry enough to provide free cooling.

The rainhood is painted to match the basic unit and must
be field-assembled before installing.

• BAS-READY ECONOMIZER - Includes a slide-in / plug-

in damper assembly with fully modulating spring-return
motor actuator with zero to 95-degree rotation capable of
introducing up to 100% outdoor air with nominal 1% leak­age type dampers.

Actuator requires 2-10 VDC input from an external
source, such as a field-installed or factory-installed BAS
controller. BAS-ready actuators have an adjustable auxil­iary end-switch for optional power exhaust control.

For units with optional VAV or Simplicity® Intelli-Com­fort™ control, a factory-installed, dry bulb sensor deter­mines if outdoor air temperature is low enough to provide
free-cooling operation. (Field-installed humidity sensors
for either outdoor air or outdoor & return air streams are

262259-YTG-F-1009

available for single enthalpy and differential enthalpy
configurations, respectively).

The rainhood is painted to match the basic unit and must
be field-assembled before installing.

• POWER EXHAUST - Our economizer options are avail­able with power exhaust. Whenever the outdoor air intake
dampers are opened for free cooling, the exhaust fan will
be energized to prevent the conditioned space from being
over-pressurized during economizer operation. BAS­ready economizer actuators have an adjustable auxiliary
end-switch to provide a range of damper positions available
to energize power exhaust. For units with optional VAV,
power exhaust is energized by means of a binary output
signal from the unit's VAV control board.

The exhaust fan, motor and controls are installed and
wired at the factory. The rain hood must be assembled
and installed in the fiel d .

The power exhaust option can only be used on bot­tom duct configurations.

• MOTORIZED OUTDOOR AIR INTAKE DAMPER -
Includes a slide-in / plug-in damper assembly with a 2­position, spring return motor actuator which opens to a
pre-set position whenever the supply air blower is oper­ating and will drive fully closed when the blower unit
shuts down.

The rain hood is painted to match the basic unit and
must be field assembled before installing.

• BAROMETRIC RELIEF DAMPER - This damper option
can be used to relieve internal building air pressure on
units with an economizer without power exhaust. This
accessory includes a rain hood, a bird screen and a fully
assembled damper. With bottom duct connections, the
damper should be mounted over the opening in the
return air panel. With horizontal ductwork, the accessory
should be mounted on the return air duct.

• PHENOLIC COATED EVAPORATOR AND CON-
DENSER COILS - Special coating process that utilizes
Technicoat 10-1" proce sses. Coating is applied by total
immersion of the complete coil for maximum protection.

• ELECTRIC HEA T ERS wired for single point power sup­ply. These nickel chromium heater elements are pro­vided with limit and automatic reset capability to prevent
operation at excessive temperatures.

• VARIABLE AIR VOLUME (VAV) - A factory-installed
variable frequency drive (VFD), mounted in the Blower
Access compartment, is used to control the speed of the
indoor blower motor in order to maintain a constant static
pressure in the supply duct. A pressure transducer and
VAV control board are mounted inside the control box.
The drive comes completely wired and pre-programmed
from the factory.

An optional, factory-installed manual bypass switch
available with factory-installed VFD can be found in the

Blower Motor Access compartment. The switch can be
used to either route power to the VFD for modulating
control of the blower motor, to bypass the drive and oper­ate the motor at full speed, or to power the drive (and not
the motor) for diagnostic purposes.

Due to space limitations, VAV is not available with any of
the factory-installed BAS options described below, but is
available with ‘BAS-ready’ models. Terminal blocks are
provided in the control box for field wiring of the cus­tomer-installed BAS.

A ‘VFD-ready’ option provides the provisions for a cus­tomer-installed drive. The unit comes with a mounting
bracket installed in the Blower Access compartment
which may accommodate other vendor’s drives depend­ing on their size. In order to utilize the unit’s mounting
bracket, the maximum recommended drive dimensions
are as follows:

For 5-hp motor applications........................10” H x 6” W x 7” D

For 7.5 thru 15-hp motor applications.........13” H x 8” W x 8” D

If the drive will not fit in the allotted space, then it will
have to be mounted elsewhere; either within the building
on a perpendicular wall which is not subjected to exces­sive temperature, vibration, humidity, dust, corrosive
gas, explosive gas, etc., or within an appropriate enclo­sure rated for outside installation to safeguard against
moisture, dust and excessive heat.

A terminal block located in the control box is provided for
field connection of the VFD controls.

• HOT GAS BYPASS - To allow for low cooling load oper­ation, a direct-acting pressure-modulating bypass control
valve installed on the system #1 discharge line is used to
divert high temperature, high pressure refrigerant around
the TXV in order to maintain a desired minimum evapo­rator pressure. HGBP is standard on all units with VAV
and optional with CV units.

• FILTER OPTIONS - Standard units are shipped with 2”
throw-away filters installed. 2” pleated and 4” pleated fil­ters are offered as a factory installed option.

• CONVENIENCE OUTLET - This 110 volt outlet can be
“powered” by the unit with a stepdown transformer or
you may order the unit with a “non-powered” conve­nience outlet that can be wired in the field.

• DISCONNECT SWITCH - For gas heat units and cooling
units with electric heat, a HACR breaker sized to the unit
is provided. For cooling only units, a switch sized to the
largest electric heat available for the particular unit is
provided. Factory installed option only.

• BAS - Building Automation System Controls (avail­able on two-system cooling product only).
