4.12 Locking function
The locking function allows the occupancy detector to be locked, so that no telegrams are
sent to the bus. The locking function is available for both switching and regulating modes for
lighting, and for the three HVAC channels. You must select a locking value to choose which
1-
bit object value (“1” or “0”) should activate locking.
When transitioning from unlocked to locked, an action can be triggered. A decision has to
be made on which state light output is in. If the channel is switched on, i.e. a follow-up time
runs, the locking can cause the situation in which this follow-up time expires before locking
is activated (“Locking prevents the channel from being activated”). Then the channel is
locked. Alternatively, locking can be active immediately. Here, there is the option to send an
ON telegram, an OFF telegram or no telegram as an action.
Reaction upon unlocking can also trigger an action: send an ON telegram, OFF telegram or
no telegram. If an ON telegram is sent, follow-up time is automatically started.
For locking, a dimming value (0-100%) can be set on a regulation output. If the device is
unlocked, it automatically jumps back to its normal regulating mode.
While the locking function is active, the remote control cannot be used.
