We have a new house with a gas bolier controlled by the above programmer.
It works fine most of the time but sometimes we get in and the boiler is on as is the programmer but the lcd screen is blank. It seems as if as though the programmer has failed but turning it off and then back on after a few minutes seems to restore it to health ~ until the next time.
The developer has replaced it twice (although I haven't seen them physically do this so it may still be the original programmer).
My question is have I been unlucky with successive failed programmers or is the something more fundamental going on thats causing the programmer to behave in this rather unreliable way?
Thanks
