Learn button (lux value)
The current lux value can be stored using the "Learn" button (operating
threshold; light value on the motion detector that determines when the
device should be activated).
As soon as the required brightness is achieved, press the "Learn"
button for three seconds, or twice within the space of five seconds.
The measured lux value is saved as the threshold during which time
the light is switched off for ten seconds.
Ensure you do not accidently cast a shadow across the detector by
covering it with your hand, for example.
The lux value can be saved as many times as you like, the position of
the lux potentiometer on the motion detector is irrelevant (see page 10).
Even in the event of a power failure, this light value will be saved.
The light value saved using the control pad is overwritten, if the BiDi
module is reset (refer to Programming/pairing the CP and BiDi module,
page 19 to 20) or if the lux potentiometer is switched to the "Learn"
position and then set to a new value.
Party mode
The light (relay 1) is switched on continuously for six hours.
The light is switched off after this time has lapsed or at the next break
of dawn (if this occurs first).
However, party mode can also be terminated prematurely. To do this,
press the relay 1 "Auto" button. Warning: If Time 1 is set to pulse, then
ON, holiday or party mode cannot be activated!
