Light Level Sensor with Occupancy Sensors and Wireless
Switches
If the light level sensor is used in conjunction with both occupancy sensors and wireless
switches then by default Occupancy Auto OFF functionality is enabled and Auto ON func-
tionality is disabled.
I.e. the default behaviour in this setup is that occupancy sensor input will only be used to
switch the light OFF in order to conserve energy. Occupancy-based Auto ON function can be
enabled by setting OccAutoOn = ON
Timer-based Auto OFF (as defined by RockerSwitchAutoOffTimer) is always disabled if at
least one occupancy sensor is linked.
If a user has switched the light OFF via a linked wireless switch then LED controller can be
prevented from switching the light back ON based on input from linked occupancy sensors
(if their Auto ON functionality is enabled) for a period defined by OccAutoOnDelay (default
15 minutes) as described before.
If light has been switched OFF due to Occupancy Auto OFF function then light will be auto-
matically turned back ON at the last state if occupancy is reported within a period set by
VacancyGraceTimer period (default 45s) even when Auto ON functionality is disabled.
Input from the light level sensor is only considered if light has been switched ON by a
linked occupancy sensor (Occupancy Auto ON function) or by a linked wireless switch.
If light is switched ON by a linked occupancy sensor (Occupancy Auto ON function) then
output light level is then set immediately according to the most recent light level sensor
data and the selected dimming parameters (2 level or 5 point dimming) as described in the
previous chapter.
If light is switched ON or dimmed UP / DOWN by a linked wireless switch then LlsAdjust-
mentDelay can be used to ensure that light level selected by the user is maintained for a
certain period irrespective of the currently available natural light as described before.
If the user short-clicks the “I” button once (switch ON light to current output level) and the
current dim level according to the defined dimming curve would be 0% (OFF) due to suffi-
cient natural light then light will be brightened to MinVoltageLevel as described before.
If light has been switched OFF (because no occupancy telegram has been received from a
linked occupancy sensor for a period defined by OccAutoOffTimer) then light will remain at
OccAutoOffLevel irrespective of light level sensor input.
Likewise, if light has been switched OFF by a linked wireless switch then it will remain in
OFF state irrespective of light level sensor input.
