Switch
If a light channel input is connected to a button, this light will be switched by every linked button or presence detector according to the autonomous function.
If no automatic switch-off time is defined (energy saving mode), then the presence detector can only switch the light on.
Additional button
The light can be switched on or off at any time using an additional button linked to this light channel.
Note that in this case, the energy saving time cannot be defined as 0, as otherwise the light would be switched off immediately after the button press – and therefore not seem to work.
Additional presence detector
An additional presence detector will always switch the light on and switch it off after the defined period of time.
