Hope someone can help me. I have a Honeywell hot water/central heating programmer that was installed when the house was built (1996). Over the last few months it's started to reset itself - the clock will go back to zero, therefore I have to reset the clock and timer all over again. It's as if there's a random power cut. It happened very occasionally, but now it's happened twice this week. I presume I will have to install a new programmer given it's age? If so, can I install any new make/model or does it have to be something very similar? I really haven't any idea. Thank you.
