Hi Peter, I haven't written in reply to either Barry Hill's original message or the replies from Jackie Cairns or John Coley, as I wasn't inicially interested in Talking Central Heating Systems, however the information you've given in the message to which I'm replying, is something I may follow up, as the flat that myself and my wife carol live in, has heaters in both our bedroom and the spare bedroom which work on the same theory as the equipment you described in your message, only we have to get sighted neighbours, friends or family to set the timers as we can't set the clocks due to the way they are designed.
