FACTORY-INSTALLED OPTIONS
•SINGLE INPUT ELECTRONIC ENTHALPY ECONO- MIZERS - Includes a slide-in /plug-in damper assembly with fully modulating spring-return motor actuator capa- ble of introducing up to 100% outdoor air with nominal 1% leakage type dampers.
The enthalpy system contains one sensor that monitors the outdoor air and determines when the air is cool enough and dry enough to provide free cooling.
The rainhood is painted to match the basic unit and must be field-assembled before installing.
•MOTORIZED OUTDOOR AIR INTAKE DAMPER - Includes a slide-in /plug-in damper assembly with a 2- position, spring return motor actuator which opens to a pre-set position whenever the supply air blower is oper- ating and will drive fully closed when the blower unit shuts down.
The rain hood is painted to match the basic unit and must be field assembled before installing.
•PHENOLIC COATED EVAPORATOR AND CON- DENSER COILS - Special coating process that utilizes Technicoat 10-1TMprocesses. Coating is applied by total immersion of the complete coil for maximum protection.
•ELECTRIC HEATERS - Wired for single point power supply. These nickel chromium heater elements are pro- vided with limit and automatic reset capability to prevent operation at excessive temperatures.
•FILTER OPTIONS - Standard units are shipped with 1” throw-away filters installed. 2” pleated filters are offered as a factory installed option.
•CONVENIENCE OUTLET - This 110 volt outlet can be “powered” by the unit with a stepdown transformer or the unit may be ordered with a “non-powered” convenience outlet that can be wired in the field.
•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.
•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 sen- sor, 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 per- form Demand Ventilation. It can also use an Outside CO2 sensor to perform Differential Demand Ventilation. It uses a Patented Comfort Ventilation algorithm to pro- vide comfortable ventilation air temperature. The pat- ented 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 sav- ings by recovering the building from the Unoccupied Set- points to the Occupied Setpoints just in time for the Occupied Time Period to begin. The Simplicity® INTELLI-Comfort™ balances space temperature, venti- lation air temperature, CO2 and humidity for ultimate comfort.
•Simplicity® INTELLI-Comfort™ with MOD LINK CON- TROL - The York® Simplicity® INTELLI-Comfort™ with Mod Link control is factory installed. It includes all the features of the INTELLI-Comfort™ control with an addi- tional control to translate communications from MOD- BUS to the BACnet MSTP protocol.
•Novar® BAS CONTROL - The Novar® ETC-3 building automation system controller is factory installed. Includes supply air sensor, return air sensor, dirty filter indicator switch, and air proving switch.
•JOHNSON CONTROLS BAS CONTROL - The Johnson Control YK-UNT-1126 building automation system con- troller is factory installed. Includes supply air sensor, return air sensor, dirty filter indicator switch, and air prov- ing switch.
•CPC BAS CONTROL - The Computer Process Controls Model 810-3060 ARTC Advanced Rooftop building auto- mation system controller is factory installed. Includes supply air sensor, return air sensor, dirty filter indicator switch and air proving switch.
•HONEYWELL BAS CONTROL - The Honeywell W7750C building automation system controller is factory installed. Includes air supply sensor, return air sensor, dirty filter indicator switch, and air proving switch.
•SMOKE DETECTORS - (supply air & return air) The smoke detectors stop operation of the unit by interrupting power to the control board if smoke is detected within the air compartment.
•COIL GUARD - Customers can purchase a coil guard kit to protect the condenser coil from damage. This is not a hail guard kit.
