If a light channel is connected to the input of a presence detector, then this light will always be automatically switched off after the defined time independently of whether an additional button or presence detector is switched on.
A presence detector light can be immediately manually switched off using an additional button.
If the time for the presence detector is to be used, then the time for the light must be set to 0. If the time for the light is to used, then the time for the presence detector must be set to 0.
The light can be switched off at any time with an additional button linked to this light channel (or on, if required). If the light is switched on via the button, it is also switched off after the defined period of time.
Note that in this case, the energy saving time cannot be 0, because otherwise the button input would be immediately switched off – and hence not seem to work.
Additional presence detector
An additional presence detector can also switch the light off after the defined period of time.
Note that in this case, if the energy saving time is defined with 0, then the on/off times for the light will vary due to the times defined by the presence detector.
