• ELECTRIC HEATERS - Wired for single point power supply. These nickel chromium heater elements are provided 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 heat pump units with electric heat, an HACR breaker sized to the unit is provided. For heat pump units without electric heat, 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 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 Unitary Products Group 036-21508-005-A-0305 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 Set- points 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 MOD LINK CONTROL - The York® Simplicity™ INTELLI-Comfort™ with Mod Link 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. • 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 controller is factory installed. Includes supply air sensor, return air sensor, dirty filter indicator switch, and air proving switch. • CPC BAS CONTROL - The Computer Process Controls Model 810-3060 ARTC Advanced Rooftop building automation 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. • STAINLESS STEEL DRAIN PAN - An optional rustproof stainless steel drain pan is available to provide years of trouble-free operation in corrosive environments. • BOTTOM DRAIN CONNECTION - An optional bottom drain connection is available for inside the curb connections for applications in cold environments to reduce freezing drain lines. • COIL GUARD - Customers can purchase a coil guard kit to protect the condenser coil from damage. This is not a hail guard kit. • PHASE MONITORS - Designed to prevent unit damage. The phase monitor will shut the unit down in an out-ofphase condition. • 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. • HINGED FILTER DOOR/“TOOLLESS” BLOWER AND ACCESS PANELS (not hinged) - This option allows for easy access and maintenance. NOTE:Knobs are shipped inside the unit to prevent shipping damage. These must be field installed for tool-less operation. FIELD-INSTALLED ACCESSORIES • SINGLE INPUT ELECTRONIC ENTHALPY ECONOMIZERS - Includes a slide-in / plug-in damper assembly with fully modulating spring-return motor actuator ca...
