    PIR Zone not to be used (scantronic 9751)

    Hi all, I've wired up a scantronic 9751 panel, but have decided to leave one of the zones not connected with a PIR as the room is to be decorated soon.

    Hi its not a combi, just a normal system that you have to switch on the hot water/ central heating manually or through the timer. As mentioned, the breather pipe that comes out of the hot water tank has a tiny little cap on it. Should this cap be closed tightly or be a little loose...
