states. The occupancy sensor can be
a room occupancy sensor or another
kind of occupancy detection (such as
a duct pressure switch*). Without an
occupancy sensor, the controller will
always be in Occupied mode.
occupancy sensor (wired to IN2 and
ICOM2 on the controller) can be used
to temporarily set the VAV box to
Standby mode when occupancy is not
sensed.
*An optional factory provided occupancy pressure switch is available for standalone fan powered terminal units to
determine occupancy by measuring duct pressure to determine whether the air handler is on (zone is occupied) or off
(zone is unoccupied).
Control Sequences
VAV boxes with Smart Equipment Controls will be factory mounted and wired according to the selected control sequence.
