Field Installed Accessories - York PREDATOR Magnum DJ 150 Technical Manual

246695-YTG-C-0708
• 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 Com-
pressors.)
• 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® Simplicity™
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 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 pro-
gramming plus holiday scheduling is built-in. Two differ-
ent modes of demand ventilation are achieved through
the Intelli-Comfort™ using CO
inside CO sensor to perform Demand Ventilation. It can
2
also use an Outside CO
Demand Ventilation. It uses a Patented Comfort Ventila-
tion algorithm to provide comfortable ventilation air tem-
perature. 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 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.

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 Magnum 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
outdoor 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 econo-
mizer control accepts an optional CO
ventilation. With single enthalpy input, the economizer
control monitors outdoor air. The dual enthalpy kit pro-
vides a second input used to monitor the return air. With
a dual input kit installed, the economizer control com-
pares the values of the two enthalpy or temperature
inputs and positions the dampers to provide the maxi-
mum 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
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
outdoor 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 econo-
mizer control accepts an optional CO
