• 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.
• DOUBLE WALL CONSTRUCTION - Optional double wall
construction is available to provide smooth inner surfaces
for easy and effective cleaning to reduce risk of dirt and
bacterial accumulation. Fiberglass insulation is
sandwiched between heavy gauge steel sheets to form a
durable, rigid casing to withstand higher working
pressures and impact forces. The heavy-duty construction
provides excellent acoustic and thermal insulation and
eliminates erosion of insulation material and
contamination of the air stream.
• BAS - Building Automation System Controls
(available on two-system cooling product only).
Simplicity® INTELLI-Comfort™ CONTROL - The York®
Simplicity® INTELLI-Comfort™ control is factory installed. It
includes a supply air sensor, a return air sensor, and an out-
side air sensor. There are provisions for a field installed dirty
filter indicator switch, an air-proving switch, an Outside Air
Humidity sensor, a Return Air Humidity sensor, an Inside IAQ
sensor, and an Outside Air IAQ sensor. Construction 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-Com-
fort™ using CO sensors. It uses an inside CO
2
perform Demand Ventilation. It can also use an Outside CO
sensor to perform Differential Demand Ventilation. It uses a
Patented Comfort Ventilation algorithm to provide comfort-
able ventilation air temperature. The patented economizer-
loading algorithm will protect the equipment when harsh
operating conditions 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 Unoccu-
pied Setpoints to the Occupied Setpoints just in time for the
Occupied Time Period to begin. The Simplicity® INTELLI-
Comfort™ balances space temperature, ventilation air tem-
perature, CO 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
Unitary Products Group
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.
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.
• STAINLESS STEEL HEAT EXCHANGER - For
applications in corrosive environments, this option
sensor to
2
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 STATIC DRIVE - May include a belt, blower pulley,
motor pulley or a motor change to enhance blower
performance.
• LOW STATIC DRIVE - May include a belt, blower pulley,
motor pulley or a motor change when standard airflow is
not required. (WR300 & WR240 only)
• 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/"TOOL FREE" BLOWER AND
ACCESS PANELS (not hinged) - This option allows for
easy access and maintenance.
