The offset can be added toor subtracted from the actualdisplayed room temperature.Default: 0.0F°/0.0C°Sets the desired Outside AirTemperature Sensor calibration(offset). The offset can be added toor subtracted from the actualdisplayed outside air temperature.Default: 0.0F°/0.0C°Sets the number of Heating stages.Default: 2Sets the number of Cooling stages.Default: 2(on): Extends fan operation by 60 seconds after a heating or coolingcycle has ended.(off): No extension of fan operation after a heating or cooling cyclehas ended.Note: The fan delay is only active when the GUI System Mode isset at Auto and the GUI Occupancy is set at Unoccupied.(None): No function is associated with an input.(RemNSB): Remote Night Setback (NSB) via a time clock input, anoccupancy sensor, or from a voltage-free contact.Contact open = Occupied; contact closed = Unoccupied(RemOVR): Temporary occupancy request via a remote input. Thisoverride function is controlled by a manual remote occupancyoverride. When enabled, this condition disables the overridecapacity of the rooftop controller.(Filter): A Filter alarm is displayed. This alarm can be connected toa differential pressure switch that monitors a filter.(Service): A Service alarm is displayed on the rooftop controllerwhen the input is energized. This input can be tied into the airconditioning unit control card, which provides an alarm should therebe a malfunction.Range: 0.0 to 12.0 hrsNote: When adjusting the TOccTime, press the UP/DOWN arrowkeys to change the time in 1-hour increments; press and holdthe UP/DOWN arrow keys to change the time in 10-hourincrements.Range: -5.0F°/-2.5C° to 5.0F°/2.5C° adjustable in 1.0F°/0.5C°incrementsRange: -5.0F°/-2.5C° to 5.0F°/2.5C° adjustable in 1.0F°/0.5C°increments(1): One stage of heating(2): Two stages of heatingNote: Two-stage rooftop controller operation reverts to one-stageoperation only when the second heating step is not required.(1): One stage of cooling(2): Two stages of coolingNote: Two-stage rooftop controller operation reverts to one-stageoperation only when the second cooling step is not required.34TEC Zoning Control System for Stand-Alone and BACnet® MS/TP Networked ApplicationsTechnical Bulletin
