Response Threshold - ABB i-bus EIB Series Operating Instructions Manual

Response Threshold

A response threshold is assigned to the dusk sensor
integrated into the unit which determines detection
activation of the watchdog (parameters to be set or
adjustment via rotary button on the unit).
This response threshold is only effective in the «Normal»
operating mode! Aside from the settings described below
intermediate positions can be adjusteds as well.
Note: Select the setting of «Moon Symbol dark» only if
the «Moon Symbol bright» setting - due to respective
conditions at the mounting location – causes the watchdog
to be activated prematurely. Please note that in such a
case scattered light emitted for example by a streetlight
may deactivate the watchdog.
