Light Level Sensor and Switches
If the light level sensor is used in conjunction with wireless switches then it is only active if
light has been switched ON or dimmed up to any output level > 0% by a linked wireless
switch.
If light has been switched OFF by a linked wireless switch then it will remain in OFF state
irrespective of light level sensor input until it is switched ON again by a linked wireless
switch.
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 initially brightened to MinVoltageLevel.
If the light level sensor is active then LlsAdjustmentDelay can be used to ensure that the
light level set by the user (via a linked wireless switch and switch ON or dim UP / DOWN
actions) is maintained for a certain period irrespective of the currently available natural
light.
Setting LlsAdjustmentDelay to 0 will cause the output light level to be adjusted according to
reported illumination as soon as a light level sensor telegram is received.
Note that this can lead to a case where the user switches the light ON during bright day-
light but the light will be regulated back immediately to 0% (OFF) level due to input from
the Light Level Sensor.
