7. TB7300 stand-alone fan coil application—3 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.

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.
