PIR APPLICATION GUIDE FOR TB7200 AND TB7300 SERIES THERMOSTATS
15 63-4526—01
8. TB7300 stand-alone fan coil application—2 levels of occupancy with an occupancy sensor cover
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 device does not detect any movement.
As soon as the PIR device detects a movement or motion, the occupancy status switches to occupied and the occupied setpoints
are used.
Anytime the PIR device detects local motion, the elapsed stand-by timer value will be reset. If no motion is detected in the zone
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 the PIR device 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.
