251934-YTG-G-07088 Johnson Controls Unitary Productssavings 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 air temperature, CO2 and humidity for ultimatecomfort.Simplicity™ INTELLI-Comfort™ with ModLINCControl - The York® Simplicity™ INTELLI-Comfort™ withModLINC control is factory installed. It includes all thefeatures of the INTELLI-Comfort™ control with anadditional control to translate communications fromMODBUS to the BACnet MSTP 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 buildingautomation 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 fieldinstallation, for the ZJ/ZR/ZF Series.• Single Input Electronic Enthalpy Economizers -Includes a slide-in / plug-in damper assembly with fullymodulating spring-return motor actuator capable ofintroducing up to 100% outdoor air with nominal 1%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 aslide-in / plug-in damper assembly with a 2-position,spring return motor actuator which opens to some pre-setposition whenever the supply air blower is operating andwill drive fully closed when the blower unit shuts down.The rain hood is painted to match the basic unit and mustbe field assembled before installing.• Roof Curbs - Fourteen-inch high roof curbs provide awater-tight seal between the unit and the finished roof.These full perimeter curbs meet the requirements of theNational Roofing Contractors Association (NRCA) and areshipped knocked-down for field assembly.They're designed to fit inside the base rails of the unit andinclude both a wood nailing strip and duct hanger supports.• High Altitude Natural Gas - Burner orifices and pilotorifices are provided for proper furnace operation ataltitudes up to 6,000 feet.• Propane - Burner orifices, pilot orifices and gas valve partsare provided to convert a natural gas furnace to propane.• High Altitude Propane - Burner orifices and pilot orificesare provided for proper furnace operation at altitudes upto 6,000 feet. This accessory supplements the basicpropane conversion kit.• Side Duct Flanges - One-inch flanges replace the supplyand return air panels on the rear of the unit to accommodatehorizontal duct connections. These flanges can also be usedindividually for bottom supply / horizontal return or horizontalsupply/bottom return. They cannot be used on units withpower exhaust.• Barometric Relief Damper - This damper accessory canbe used to relieve internal building air pressure on unitswith an economizer without power exhaust. Thisaccessory includes a rain hood, a bird screen and a fullyassembled damper. With bottom duct connections, thedamper should be mounted over the opening in the returnair panel. With horizontal ductwork, the accessory shouldbe mounted on the return air duct.• High Static Drive - May include a belt, blower pulley,motor pulley or a motor change to enhance blowerperformance.• Enthalpy Accessory Control Kit - This kit contains therequired components to convert a single enthalpyeconomizer to dual enthalpy.• Burglar Bars - Mount in the supply and return openingsto prevent entry into the duct work.• Flue Exhaust Extension Kit - In locations with wind orweather conditions which may interfere with properexhausting of furnace combustion products, this kit can beinstalled to prevent the flue exhaust from entering nearbyfresh air intakes.• Wood Skid - Allows unit to be handled with 90" forks.• CO2 Sensor - Senses CO 2 levels and automaticallyoverrides the economizer when levels rise above thepresent limits.• Coil Guard - Customers can purchase a coil guard kit toprotect the condenser coil from damage. This is not a hailguard kit.• Phase Monitors - Designed to prevent unit damage. Thephase monitor will shut the unit down in an out-of phasecondition.Guide SpecificationsGeneralUnits shall be manufactured by York International UnitaryProducts Group in an ISO 9001 certified facility.York's ZJ/ZR/ZF units are convertible single package units. Allmodels have four independent refrigerant circuits for efficientpart load operation and maximum comfort control. Although theunits are primarily designed for curb mounting on a roof, they
