246721-YTG-C-06068 Unitary Products Group• Technicoat Condenser Coils - The condenser coils arecoated with a phenolic coating for protection against cor-rosion due to harsh environments.• Technicoat Evaporator Coil - The evaporator coils arecoated with a phenolic coating for protection against cor-rosion due to harsh environments.• BAS - Building Automation System ControlsSimplicity® Intelli-Comfort™ Control - The YorkSimplicity® Intelli-Comfort™ control is factory installed. Itincludes a supply air sensor, a return air sensor, and anoutside air sensor. There are provisions for a fieldinstalled dirty filter indicator switch, an air-proving switch,an Outside Air Humidity sensor, a Return Air Humiditysensor, an Inside IAQ sensor, and an Outside Air IAQsensor. Construction mode operation, 365-day real timeclock with 7 day programming plus holiday scheduling isbuilt-in. Two different modes of demand ventilation areachieved through the Intelli-Comfort™ using CO 2sensors. It uses an inside CO2 sensor to performDemand Ventilation. It can also use an Outside CO2sensor to perform Differential Demand Ventilation. Ituses a Patented Comfort Ventilation algorithm to providecomfortable ventilation air temperature. The patentedeconomizer-loading algorithm will protect the equipmentwhen harsh operating conditions exist. Humidity in theoccupied space or return duct can be monitored andcontrolled via humidity sensors and the on-boardconnection for hot gas re-heat system. It uses theIntelli-Start algorithm to maximize energy savings byrecovering the building from the Unoccupied Setpoints tothe Occupied Setpoints just in time for the OccupiedTime Period to begin. The Simplicity® Intelli-Comfort™balances space temperature, ventilation air temperature,CO 2 and humidity for ultimate comfort.• Simplicity® Intelli-Comfort™ with ModLINC Control -The York Simplicity® Intelli-Comfort™ with ModLINCcontrol is factory installed. It includes all the features ofthe Intelli-Comfort™ control with an additional control totranslate communications from MODBUS to the BACnetMSTP protocol.• Novar® BAS Control - The Novar® ETC-3 buildingautomation system controller is factory installed. Incudessupply air sensor, return air sensor, dirty filter indicatorswitch, and air proving switch.• Johnson Controls BAS Control - The Johnson ControlYK-UNT-1126 building automation system controller isfactory installed. Includes supply air sensor, return airsensor, dirty filter indicator switch, and air proving switch.• CPC BAS Control - The Computer Process ControlsModel 810-3060 ARTC Advanced Rooftop building auto-mation system controller is factory installed. Includessupply air sensor, return air sensor, dirty filter indicatorswitch and air proving switch.• Honeywell BAS Control - The Honeywell W7750Cbuilding automation system controller is factory installed.Includes air supply sensor, return air sensor, dirty filterindicator switch, and air proving switch.FIELD INSTALLED ACCESSORIESYORK® offers several equipment accessories for field instal-lation, for the Predator® line.• Downflow Economizer - (With barometric relief) - Theeconomizer is provided with a single enthalpy input. Theeconomizer is 2% low leakage type. The economizer hasspring return, fully modulating damper actuators and iscapable of introducing up to 100% outdoor air. As the out-door air intake dampers open, the return air dampersclose. The changeover from mechanical refrigeration toeconomizer operation is regulated by the standard singleenthalpy input. There is an optional input dual dry bulbavailable. To meet regulated air standards, the economizercontrol accepts an optional CO2 input for demand ventila-tion. With single enthalpy input, the economizer controlmonitors outdoor air. The dual enthalpy kit provides a sec-ond input used to monitor the return air. With a dual inputkit installed, the economizer control compares the valuesof the two enthalpy or temperature inputs and positions thedampers to provide the maximum efficiency possible.• Horizontal Economizer - (Without barometric relief) -All features of the downflow economizer exist except youmust order the duct mount barometric relief separately.You must order a 1EH0408 if you are installing apower exhaust. You can order a 1RD0411 BarometricRelief for horizontal flow economizer.• Slab Economizer for Energy Recovery Ventilator-(Without barometric relief or Fresh Air Hood) - Theeconomizer is provided with a single enthalpy input. Theeconomizer is 2% low leakage type. The economizer hasspring return, fully modulating damper actuators and iscapable of introducing up to 100% outdoor air. As the out-door air intake dampers open, the return air dampersclose. The changeover from mechanical refrigeration toeconomizer operation is regulated by the standard singleenthalpy input. There is an optional input dual dry bulbavailable. To meet regulated air standards, the economizercontrol accepts an optional CO2 input for demand ventila-tion.With single enthalpy input, the economizer controlmonitors outdoor air. The dual enthalpy kit provides a sec-ond input used to monitor the return air. With a dual inputkit installed, the economizer control compares the valuesof the two enthalpy or temperature inputs and positions thedampers to provide the maximum efficiency possible.You can order 1EH0409 Barometric Relief/FA Hood forfield installations without an ERV.• Dual Enthalpy Control, Accessory - This kit containsthe required components to convert a single enthalpyeconomizer to dual enthalpy.• Barometric Relief Damper - Zero to 100% capacitybarometric relief dampers for use with horizontal flow, orfield installed slab economizers.
