air temperature. The patented economizer-loading algo-
rithm 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 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, CO2 and humidity for ultimate comfort.
Simplicity
®
 INTELLI-Comfort™ with MOD LINK CON-
TROL - The York® Simplicity
®
 INTELLI-Comfort™ with 
Mod Link control is factory installed. It includes all the 
features of the INTELLI-Comfort™ control with an addi-
tional control to translate communications from MOD-
BUS 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 con-
troller is factory installed. Includes supply air sensor, 
return air sensor, dirty filter indicator switch, and air prov-
ing switch.
CPC BAS CONTROL - The Computer Process Controls 
Model 810-3060 ARTC Advanced Rooftop building auto-
mation system controller is factory installed. Includes 
supply 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.
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.
COIL GUARD - Customers can purchase a coil guard kit 
to protect the condenser coil from damage. This is not a 
hail guard kit.
STAINLESS STEEL HEAT EXCHANGER - For applica-
tions 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 environ-
ments.
BOTTOM DRAIN CONNECTION - An optional bottom 
drain connection is available for inside the curb connec-
tions for applications in cold environments to reduce 
freezing drain lines.
PHASE MONITORS - Designed to prevent unit damage. 
The phase monitor will shut the unit down in an out-of-
phase condition.
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 inside the unit to prevent ship-
ping damage. These must be field installed for 
tool-less operation.
FIELD-INSTALLED ACCESSORIES
SINGLE INPUT ELECTRONIC ENTHALPY ECONO-
MIZERS
 - Includes a slide-in / plug-in damper assembly 
with fully modulating spring-return motor actuator capa-
ble 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.
ELECTRIC HEATERS wired for single point power sup-
ply. These nickel chromium heater elements are pro-
vided with limit and automatic reset capability to prevent 
operation at excessive temperatures.
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.
