MS8250 Room Controller
PIR Sensor Details
The internal MS8250 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.

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 two (2) modes in the Room Controller: stand-by and occupied for a stand-alone solution. Refer to the two (2)
diagrams below for the Room Controller internal occupancy states transition.

3. Install additional motion sensor in the bathroom.
4. Install additional motion sensor for better motion detection in the entire room.
More aggressive energy savings logic but may cause bad guest experience (when guest
is sleeping or not moving).
Good energy savings logic and better guest experience even when the guest is sleeping
or not moving.
