11. TB7300 stand-alone fan coil application—3 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 a PIR device detects a movement or motion, the occupancy status switches to occupied and the occupied setpoints
are used. The room will then be in occupied mode until a door toggle is detected.
If a door toggle is detected, then the room switches to stand-by mode and the stand-by setpoints are used. If any occupants are
left in the room, local movements must be seen to resume the occupied mode.
While in stand-by mode, if no motion is detected in the zone for the entire unoccupied timer duration, then the room switches to
unoccupied mode and the unoccupied setpoints are used.
At anytime, if the PIR device detects a local movement or motion, the occupancy status switches to occupied and the occupied
setpoints are used.
