6 Johnson Controls Unitary Products
• Phase Monitors - Designed to prevent unit damage. The
phase monitor will shut the unit down in an out-of phase
condition. (Standard on units with Scroll Compressors.)
• Coil Guard - Customers can purchase a coil guard kit to
protect the condenser coil from damage. Additionally,
this kit stops animals and foreign objects from entering
the space between the inner condenser coil and the
main cabinet. This is not a hail guard kit.
• Dirty Filter Switch - This kit includes a differential pres-
sure switch that energizes the fault light on the unit ther-
mostat, indicating that there is an abnormally high
pressure drop across the filters. Factory installed option
or field installed accessory.
• Technicoat Condenser Coils - The condenser coils are
coated with a phenolic coating for protection against cor-
rosion due to harsh environments.
• Technicoat Evaporator Coil - The evaporator coils are
coated with a phenolic coating for protection against cor-
rosion due to harsh environments.
• BAS - Building Automation System Controls Simplic-
ity™ INTELLI-Comfort™ Control - The York® Simplic-
ity™ INTELLI-Comfort™ control is factory installed. It
includes a supply air sensor, a return air sensor, and an
outside air sensor. There are provisions for a field installed
dirty filter indicator switch, an air-proving switch, an Out-
side Air Humidity sensor, a Return Air Humidity sensor, an
Inside IAQ sensor, and an Outside Air IAQ sensor. Con-
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 Ventilation.
It can also use an Outside CO
2
sensor to perform Differen-
tial Demand Ventilation. It uses a Patented Comfort Venti-
lation 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 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™ bal-
ances space temperature, ventilation air temperature, CO
2
and humidity for ultimate comfort.
• Simplicity™ INTELLI-Comfort™ with ModLINC
Control - The York® Simplicity™ INTELLI-Comfort™
with ModLINC control is factory installed. It includes all
the features 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. Incudes
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 controller 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
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 and
change-over bypass systems.
FIELD INSTALLED ACCESSORIES
YORK
®
offers several equipment accessories for field instal-
lation, for the Predator ® line.
• Downflow Economizer - (With barometric relief) - The
economizer is provided with a single enthalpy input. The
economizer is 2% low leakage type. The economizer has
spring return, fully modulating damper actuators and is
capable of introducing up to 100% outdoor air. As the out-
door air intake dampers open, the return air dampers
close. The changeover from mechanical refrigeration to
economizer operation is regulated by the standard single
enthalpy input. There is an optional input dual dry bulb
available. To meet regulated air standards, the economizer
control accepts an optional CO
2
input for demand ventila-
tion. With single enthalpy input, the economizer control
monitors outdoor air. The dual enthalpy kit provides a sec-
ond input used to monitor the return air. With a dual input
kit installed, the economizer control compares the values
of the two enthalpy or temperature inputs and positions the
dampers to provide the maximum efficiency possible
• Horizontal Economizer - (Without barometric relief) -
All features of the downflow economizer exist except you
must order the duct mount barometric relief separately.
You must order a 1EH0408 if you are installing a
power exhaust. You can order a 1RD0411 Barometric
Relief for horizontal flow economizer.
• Slab Economizer for Energy Recovery Ventilator-
(Without barometric relief or Fresh Air Hood) - The
economizer is provided with a single enthalpy input. The
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.
