12. TB7300 stand-alone fan coil application—2 levels of occupancy with dual PIR sensors
Sequence of operation:
At initial power-up, when the thermostat 24 Vac power supply is applied; the initial occupancy of the zone will be stand-by mode if
the PIR devices do not detect any movement.
As soon as either of the PIR devices detect a movement or motion, the occupancy status switches to occupied and the occupied
setpoints are used.
Anytime local motion is detected by one of the PIR devices, the elapsed stand-by timer value will be reset. If either PIR devices in
the zone detect no motion for the entire stand-by timer duration, then the room switches to stand-by mode and the stand-by
setpoints are used.
At anytime, if one of the PIR devices detects a local movement or motion, the occupancy status switches to occupied and the
occupied setpoints are used.
The local zone never goes into unoccupied mode and the unoccupied setpoints are never used.
