Release input

The boiler has a release input (normally open contact). This input relates
to the RL terminals of the connection terminal block.
If this contact is closed when there is a heat demand, the boiler will be
blocked after a waiting time.
Change the waiting time of the input by configuring the AP008 parameter.
Important
Only suitable for potential-free contacts.
