Passive Infra-Red Sensor Sequence of Operation
Initially, the Controller is in Stand-by mode and Stand-by setpoints are used for the Controller. When the Passive
Infra-Red (PIR) sensor detects motion, the Occupancy status switches to Occupied and the Stand-By Time timer
is reset. The Occupied setpoints are used for this operation.
If no motion is detected in the room for the entire Stand-By Time duration (adjustable parameter), the room
switches to Stand-by mode and Stand-by setpoints are used. While in Stand-by mode, if no motion is detected
for the entire Unoccupied Time period (adjustable parameter), the room switches to Unoccupied mode and
uses its Unoccupied setpoints. While in Stand-By or Unoccupied mode, any motion switches the room back to
Occupied mode.
Typical Detection Pattern for PIR Lens
Recommended installation
height for PIR sensor:
4 - 5 ft. / 1.2-1.5 m
Sensor Ranges
A = 20 ft. / 6.1 m
B = 14 ft. / 4.3 m
C = 11 ft. / 3.4 m

Energy Savings

PIR can maximize your
energy saving from
10-30% by adjusting
temperature set points in
unoccupied zones during
scheduled periods.
