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

Initially, the controller is in Stand-by mode. Stand-by setpoints are used at the controller. As soon as the
PIR detects motion, the Occupancy status switches to Occupied and the Stand-By Time timer is reset. The
Occupied setpoints are used. If no motion is detected in the room for the entire Stand-By Time duration
(adjustable parameter), the room then 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 will switch the room back to Occupied mode.
