York DR150, DR120, DR090 manual Field Installed Accessories, YTG-C-0606

•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 CO2 sensors. It uses an inside CO2 sensor to perform Demand Ventilation. It can also use an Outside CO2 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, CO2 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.

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 CO2 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 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 CO2 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.

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.
