A.3 ROOM CONTROLER PIR SENSOR DETAILS
The internal Room Controller PIR sensor only detect lateral movement. It cannot detect movement when a person is moving toward it.
It will not detect someone seating on a chair and/or lying on the bed.

A.4 RECOMMENDATIONS FOR INSTALLATIONS
1. Install the Room Controller to cover more lateral movement.
2. Install a door sensor, the internal Room Controller occupancy logic works better with a door sensor. Once a motion is detected
after a door is opened, the room stays in occupied state until the door is opened again which put the Room Controller in stand-
by mode and if there is a motion then it goes back in occupied mode. It is also recommended to disable the unoccupied mode,
set the “unoccupied time” to 0, so there is only 2 modes in the Room Controller: stand-by and occupied for a stand-alone
solution. Please refer to the two(2) diagrams below for the Room Controller internal occupancy states transition.
