Functional behaviour of wireless occupancy sensors
Wireless occupancy sensors are used to switch OFF – and optionally switch ON – the light
based on occupancy in a room.
To do so, energy harvesting wireless occupancy sensors report motion immediately if it is
detected for the first time after a period without motion. This enables LED zone controllers
to immediately switch ON the light upon motion detection.
Subsequently, detected motion is reported via periodical status update telegrams (e.g. eve-
ry 2 minutes). These telegrams will cause the light to remain ON.
If no telegram indicating detected motion has been received for a certain period of time
(e.g. 15 minutes) then the room is considered unoccupied. Light is switched OFF after such
period has elapsed without reported motion. No dedicated “unoccupied” telegram has to be
sent.
EnOcean TCM 330 based LED controllers can receive input from up to 10 wireless occupan-
cy sensors using EnOcean Equipment Profiles (EEP) A5-07-01, A5-07-02 or A5-07-03.
The following actions are supported for wireless occupancy sensors:
n
Occupancy-based Auto OFF
If none of the linked wireless occupancy sensors reports motion for a period defined by
OccAutoOffTimer (default 15min) then light is set to OccAutoOffLevel (default 0%).
This feature can be disabled by setting OccAutoOffTimer to 0.
Note that OccAutoOffTimer should not be set to a period shorter than the normal motion
reporting interval (typically around 2 minutes) as otherwise the light would be switched
OFF even though the room is still occupied.
Ramp-down speed is configurable via SensorRampDownSpeed (default 20% per sec-
ond).
n
Occupancy-based Auto ON
If at least one sensor reports motion then light is set to OccAutoOnLevel (default 100%).
Ramp-up speed is configurable via SensorRampUpSpeed (default 20% per second).
