I would really appreciate some help. I am looking to replace my switchmaster 805 which doesn't work. The central heating has to be on constantly to get hot water. The timer doesn't work either.
I have read many posts but found nothing conclusive about which is the best up to date replacement.
Any advice would be appreciated, many thanks
