uses an inside CO2 sensor to perform Demand Ventila- tion. It can also use an Outside CO2 sensor to perform Dif- ferential 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 condi- tions 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 CON- TROL - The York® Simplicity® INTELLI-Comfort™ with ModLINC 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.

Factory installed smoke detectors in the return air may be subjected to freezing temperatures during “off” times due to outside air infiltration. These smoke detectors have an operation limit of 32°F to 131°F. Smoke detectors installed in areas that could be outside those limitations will have to be moved to prevent having false alarms.

•COIL GUARD - Customers can purchase a coil guard kit to protect the condenser coil from damage. This is not a hail guard kit.

•STAINLESS STEEL HEAT EXCHANGER - For applica- tions in corrosive environments, this option provides a full stainless steel heat exchanger assembly.

•STAINLESS STEEL DRAIN PAN - An optional rust- proof stainless steel drain pan is available to provide years of trouble-free operation in corrosive environ- ments.

•PHASE MONITORS - Designed to prevent unit damage. The phase monitor will shut the unit down in an out-of- phase condition.

•HIGH STATIC DRIVE - Includes a belt and blower pulley upgrade to enhance blower performance.

•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/”TOOL FREE” BLOWER AND ACCESS PANELS (not hinged) - This option allows for easy access and maintenance.

NOTE:Knobs are shipped separately within the unit to prevent shipping damage. These must be field installed for tool free operation.

•HINGED/"TOOL FREE" BLOWER, BLOWER MOTOR, FILTER AND ELECTRIC ACCESS PANELS - This option allows for complete hinged and tool free access to the unit's blower, blower motor, filters and electrical panel sections.

FIELD-INSTALLED ACCESSORIES

•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 some pre-set position whenever the supply air blower is operating 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.

•ROOF CURBS - Fourteen-inch high roof curbs provide a water-tight seal between the unit and the finished roof.
