Unitary Products Group 9
struction mode operation, 365-day real time clock with 7
day programming plus holiday scheduling is built-in. Two
different modes of demand ventilation are achieved
through the INTELLI-Comfort™ using CO
2
sensors. It
uses an inside CO
2
sensor to perform Demand Ventila-
tion. It can also use an Outside CO
2
sensor to perform Dif-
ferential Demand Ventilation. It uses a Patented Comfort
Ventilation algorithm to provide comfortable ventilation air
temperature. The patented economizer-loading algorithm
will protect the equipment when harsh operating condi-
tions exist. Humidity in the occupied space or return duct
can be monitored and controlled via humidity sensors and
the on-board connection for hot gas re-heat system. It
uses the INTELLI-Start™ algorithm to maximize energy
savings by recovering the building from the Unoccupied
Setpoints to the Occupied Setpoints just in time for the
Occupied Time Period to begin. The Simplicity® INTELLI-
Comfort™ balances space temperature, ventilation air
temperature, CO
2
and humidity for ultimate comfort.
Simplicity® INTELLI-Comfort™ with ModLINC CON-
TROL - The York® Simplicity® INTELLI-Comfort™ with
ModLINC control is factory installed. It includes all the fea-
tures of the INTELLI-Comfort™ control with an additional
control to translate communications from MODBUS to the
BACnet MSTP protocol.
Novar® BAS CONTROL - The Novar® ETC-3 building
automation system controller is factory installed. Includes
supply air sensor, return air sensor, dirty filter indicator
switch, and air proving switch.
JOHNSON CONTROLS BAS CONTROL - The Johnson
Control YK-UNT-1126 building automation system control-
ler is factory installed. Includes supply air sensor, return
air sensor, dirty filter indicator switch, and air proving
switch.
CPC BAS CONTROL - The Computer Process Controls
Model 810-3060 ARTC Advanced Rooftop building auto-
mation system controller is factory installed. Includes sup-
ply air sensor, return air sensor, dirty filter indicator switch
and air proving switch.
HONEYWELL BAS CONTROL - The Honeywell W7750C
building automation system controller is factory installed.
Includes air supply sensor, return air sensor, dirty filter
indicator switch, and air proving switch.
• COIL GUARD - Customers can purchase a coil guard kit
to protect the condenser coil from damage. This is not a
hail guard kit.
• SMOKE DETECTORS - (supply air & return air) The
smoke detectors stop operation of the unit by interrupting
power to the control board if smoke is detected within the
air compartment.
• STAINLESS STEEL HEAT EXCHANGER - For
applications in corrosive environments, this option
provides a full stainless steel heat exchanger assembly.
• STAINLESS STEEL DRAIN PAN - An optional rust-proof
stainless steel drain pan is available to provide years of
trouble-free operation in corrosive environments.
• PHASE MONITORS - Designed to prevent unit damage.
The phase monitor will shut the unit down in an out-of-
phase condition.
• HIGH SPEED DRIVE - May include a belt, blower pulley,
motor pulley or a motor change to enhance blower
performance.
• DIRTY FILTER SWITCH - This kit includes a differential
pressure switch that energizes the fault light on the unit
thermostat, indicating that there is an abnormally high
pressure drop across the filters. Factory installed option or
field installed accessory.
• HINGED FILTER DOOR/”TOOLLESS” BLOWER AND
ACCESS PANELS (not hinged) - This option allows for
easy access and maintenance.
NOTE: Knobs are shipped separately within the unit to
prevent shipping damage. These must be field
installed for toolless operation.
• LOW SPEED DRIVE - Includes a motor change when
high airflow is not required. (WR300 & WR240 only)
FIELD-INSTALLED ACCESSORIES
• SINGLE INPUT ELECTRONIC ENTHALPY
ECONOMIZERS - 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.
• MOTORIZED OUTDOOR AIR INTAKE DAMPER -
Includes a slide-in / plug-in damper assembly with a 2-
position, spring return motor actuator which opens to
some 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.
Factory installed smoke detectors in the return air,
may be subjected to freezing temperatures during
“off” times due to out side air infiltration. these smoke
detectors have an operational limit of 32°F to 131°F.
smoke detectors installed in areas that could be out
side those limitations will have to be moved to prevent
having false alarms.
