Field Installed Accessories - York PREDATOR MagnaDRY DR090 Technical Manual

• 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
Simplicity® 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 programming plus holiday scheduling is
built-in. Two different modes of demand ventilation are
achieved through the Intelli-Comfort™ using CO
sensors. It uses an inside CO
Demand Ventilation. It can also use an Outside CO
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
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.

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
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
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
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.
You can order 1EH0409 Barometric Relief/FA Hood for
field installations without an ERV.
• Dual Enthalpy Control, Accessory - This kit contains
the required components to convert a single enthalpy
economizer to dual enthalpy.
• Barometric Relief Damper - Zero to 100% capacity
barometric relief dampers for use with horizontal flow, or
field installed slab economizers.
