261660-YTG-C-0707Unitary Products Group 7uses 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 ComfortVentilation algorithm to provide comfortable ventilation airtemperature. The patented economizer-loading algorithmwill protect the equipment when harsh operating condi-tions exist. Humidity in the occupied space or return ductcan be monitored and controlled via humidity sensors andthe on-board connection for hot gas re-heat system. Ituses the INTELLI-Start™ algorithm to maximize energysavings by recovering the building from the UnoccupiedSetpoints to the Occupied Setpoints just in time for theOccupied Time Period to begin. The Simplicity® INTELLI-Comfort™ balances space temperature, ventilation airtemperature, CO2 and humidity for ultimate comfort.Simplicity® INTELLI-Comfort™ with ModLINC CON-TROL - The York® Simplicity® INTELLI-Comfort™ withModLINC control is factory installed. It includes all thefeatures 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 buildingautomation system controller is factory installed.Includes supply air sensor, return air sensor, dirty filterindicator switch, and air proving switch.JOHNSON CONTROLS BAS CONTROL - The JohnsonControl 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 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 HoneywellW7750C building automation system controller is factoryinstalled. Includes air supply sensor, return air sensor,dirty filter indicator switch, and air proving switch.• SMOKE DETECTORS - (supply air & return air) Thesmoke detectors stop operation of the unit by interruptingpower to the control board if smoke is detected within theair compartment.• COIL GUARD - Customers can purchase a coil guard kitto protect the condenser coil from damage. This is not ahail guard kit.• STAINLESS STEEL HEAT EXCHANGER - For applica-tions in corrosive environments, this option provides afull stainless steel heat exchanger assembly.• STAINLESS STEEL DRAIN PAN - An optional rust-proof stainless steel drain pan is available to provideyears 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 pulleyupgrade to enhance blower performance.• DIRTY FILTER SWITCH - This kit includes a differentialpressure switch that energizes the fault light on the unitthermostat, indicating that there is an abnormally highpressure drop across the filters. Factory installed optionor field installed accessory.• HINGED FILTER DOOR/”TOOL FREE” BLOWER ANDACCESS PANELS (not hinged) - This option allows foreasy access and maintenance.NOTE:Knobs are shipped separately within the unit toprevent shipping damage. These must be fieldinstalled for tool free operation.• HINGED/"TOOL FREE" BLOWER, BLOWER MOTOR,FILTER AND ELECTRIC ACCESS PANELS - Thisoption allows for complete hinged and tool free access tothe unit's blower, blower motor, filters and electrical panelsections.FIELD-INSTALLED ACCESSORIES• SINGLE INPUT ELECTRONIC ENTHALPY ECONO-MIZERS - Includes a slide-in / plug-in damper assemblywith fully modulating spring-return motor actuator capa-ble of introducing up to 100% outdoor air with nominal1% leakage type dampers.The enthalpy system contains one sensor that monitorsthe outdoor air and determines when the air is coolenough and dry enough to provide free cooling.The rainhood is painted to match the basic unit and mustbe 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 tosome pre-set position whenever the supply air blower isoperating and will drive fully closed when the blower unitshuts down.The rain hood is painted to match the basic unit andmust be field assembled before installing.• ROOF CURBS - Fourteen-inch high roof curbs provide awater-tight seal between the unit and the finished roof.Factory installed smoke detectors in the return airmay be subjected to freezing temperatures during“off” times due to outside air infiltration. Thesesmoke detectors have an operation limit of 32°F to131°F. Smoke detectors installed in areas thatcould be outside those limitations will have to bemoved to prevent having false alarms.
