RTU Open 63DefaultRange: -40 to 245°FDemand LevelPoint Name/Description Occupied 1 2 3Occupied Cooling 1 – YellowThe space temperature must be greater than the Occupied Cooling 1 setpoint forthe VVT Master to consider the zone a cooling caller in a linked system. In a single-zone application, the cooling requirement begins as soon as the spacetemperature exceeds the Occupied Cooling setpoint. We recommend that theOccupied Cooling 1 value be set no less than 0.5°F above the Occupied Cooling75°Fsetpoint.76°F 77°F 79°FOccupied Cooling 2 – OrangeThe space temperature must be greater than the Occupied Cooling 2 setpoint togenerate a high space temperature alarm. We recommend that this value be setno less than 0.5°F above the Occupied Cooling 176°Fsetpoint.78°F 78°F 81°FUnoccupied SetpointsPoint Name/Description Default/RangeUnoccupied Heating D:– GrayThe heating setpoint the controller maintains while in unoccupied mode.
