A T612DFH-4+PIR Thermostat Controller (or a T612DFH-4 Thermostat Controller equipped with a PIR accessory cover) provides advanced occupancy logic.
Note: The PIR strategy is an occupied strategy. If the thermostat controller is programmed to be Unoccupied, the PIR function does not have an effect on the occupancy strategy.
The thermostat controller automatically switches occupancy levels from Occupied to Standby and Unoccupied as required, when local movement is sensed.
Occupancy sensing is enabled only if a PIR cover is installed on the thermostat controller (PIR models) or if a remote input is configured as a remote PIR sensor (MotionNO or MotionNC).
