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

Provides rooftop system integration for YCCS single 
zone, change-over bypass and VAV systems.
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.
PHASE MONITORS - Designed to prevent unit damage. 
The phase monitor will shut the unit down in an out-of-
phase condition.
HIGH STATIC DRIVE - Includes a belt and blower pulley 
upgrade 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/”TOOL FREE” 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 tool free operation.
HINGED/"TOOL FREE" BLOWER, BLOWER MOTOR, 
FILTER AND ELECTRIC ACCESS PANELS -
 This 
option allows for complete hinged and tool free access to 
the unit's blower, blower motor, filters and electrical panel 
sections.
Factory installed smoke detectors in the return air
may be subjected to freezing temperatures during
“off” times due to outside air infiltration. These
smoke detectors have an operation limit of 32°F to
131°F. Smoke detectors installed in areas that
could be outside those limitations will have to be
moved to prevent having false alarms.
