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-Comfort™
using CO
2
sensors. It uses an inside CO
2
sensor to per-
form Demand Ventilation. It can also use an Outside CO
2
sensor to perform Differential 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 conditions exist. Humidity in the
occupied space or return duct can be monitored and
controlled via humidity sensors and the on-board con-
nection for hot gas re-heat system. It uses the INTELLI-
Start™ algorithm to maximize energy savings by recov-
ering the building from the Unoccupied Setpoints to the
Occupied Setpoints just in time for the Occupied Time
Period to begin. The Simplicity® INTELLI-Comfort™ bal-
ances 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
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® building automa-
tion 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 John-
son Control YK-UNT-1126 building automation system
controller is factory installed. Includes supply air sen-
sor, 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
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.
YORK COMMERCIAL COMFORT SYSTEM (YCCS) -
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 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 per-
formance.
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 pre-
vent shipping damage. These must be field installed
for tool free operation.
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.
