Hi
I have the above (model a/27) and the grasslin em/1 digi 20 timer has stopped working. I can't seem to programme in more than one time into it so at the moment I am having to manually turn on and off the heating. Is it possible to buy a generic timer for the boiler (there are three electrodes that it plugs into). Or do I have to buy something from grasslin although the timer I have does not seem to be available on their website.
Many thanks
Matthew
