Locking Function
You can use the locking function to set a specific channel to pressed/released and lock it in this position. The state of the output channel cannot be changed by other control commands as long as the lock is active. You can enable the locking function individually for each switching channel.

Once the locking function has been enabled, a new group object called Lock is available for the switching channel. You can activate and deactivate a channel lock using the locking object.
If the locking object receives a telegram with the object value that you set for the parameter Lock, all other channel functions are disabled. You can define the reaction using the parameter Behavior at start of locking.
If the locking object receives a telegram with the object value opposite of that for activation, the lock is canceled and the output relay adopts the state that you defined in the parameter Behavior at end of locking.
The locking function always switches without a delay. During a lock, the most recent switching telegram is saved and delay times and staircase lighting times continue.
