• 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.
• IntelliSpeed™ Supply Fan Control Option (ASHRAE
90.1 compliant, section 6.4.3.10) - Units configured with
the IntelliSpeed™ Supply Fan Option will contain a VFD
for variable volume supply fan operation. This option
allows the supply fan RPM to vary based on the number
of compressors or heating stages energized. The
economizer's minimum position will also be configurable
to vary based on the supply fan VFD frequency output.
• Disconnect Switch - For heat pump units with electric
heat, a HACR breaker sized to the unit is provided. For
heat pump 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.
• Filters – 2" Pleated MERV 7 or 4" Pleated MERV 13 are
available to meet LEED requirements. A 2" Throwaway is
shipped as standard.
• 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
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.
• ElectroFin® E-coat Condenser Coils - The condenser
coils are coated with an epoxy polymer coating to protect
against corrosion.
• ElectroFin® E-coat Evaporator Coils - The evaporator
coils are coated with an epoxy polymer coating to protect
against corrosion.
Control Options
• BAS - Building Automation System Controls Simplicity
INTELLI-Comfort II™ Control - The York
INTELLI-Comfort II™ 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 II™ using CO
inside CO sensor to perform Demand Ventilation. It can

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. 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
