Control Options - York PREDATOR R-410A Technical Manual

• Motorized Outdoor Air Damper - The motorized outdoor
air damper includes a slide-in/plug-in damper assembly
with an outdoor air hood and filters. The outdoor air
dampers open to the preset position when the indoor fan
motor is energized. The damper has a range of 0% to
100% outdoor air entry. Factory installed option or field
installed accessory.
• Alternate Indoor Blower Motor - For applications with
high static restrictions, units are offered with optional
indoor motors that provide higher static output and/or
higher airflow, depending upon the installer's needs.
• Aluminized Steel Gas Heat Exchanger - For
applications in non-corrosive environments.
• Stainless Steel Gas Heat Exchanger - For applications
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.
• Electric Heaters - The electric heaters range from 9kW to
54kW and are available in all the voltage options of the
base units. All heaters are dual staged. All heaters are
intended for single point power supply.
• Disconnect Switch - For gas heat units and cooling units
with electric heat, a HACR breaker sized to the unit is
provided. For cooling only units, a switch sized to the
largest electric heat available for the particular unit is
provided. Factory installed option only.
• Convenience Outlet - (Non-Powered/Powered) - This
option locates a 120V single-phase GFCI outlet with cover,
on the corner of the unit housing adjacent to the
compressors. The "Non-powered" option requires the
installer to provide the 120V single-phase power source and
wiring. The "Powered" option is powered by a stepdown
transformer in the unit. Factory installed option only.
• Smoke Detectors - The smoke detectors stop operation
of the unit by interrupting power to the control board if
smoke is detected within the air compartment. Available
for both the supply and/or return air.
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.
• 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.
Johnson Controls Unitary Products
• 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.
• Technicoat Condenser Coils - The condenser coils are
coated with a phenolic coating for protection against
corrosion due to harsh environments.
• Technicoat Evaporator Coil - The evaporator coils are
coated with a phenolic coating for protection against
corrosion due to harsh environments.
• Hot Gas Bypass - Allows operation during low load
conditions while avoiding coil frosting and damage to
compressor. When suction pressure falls below valve
setpoint, the valve modulates hot gas to the inlet of the
evaporator.

Control Options

• BAS - Building Automation System Controls Simplicity
INTELLI-Comfort™ Control - The York
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
programming plus holiday scheduling is built-in. Two
different 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 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 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
balances space temperature, ventilation air temperature,
CO and humidity for ultimate comfort.
