Hi All,
New to this site. I have a 6-8yr old Ravenheat 820/20 combination boiler with timer. The timer has started re-setting itself everyfew minutes or so. On some occasions it even clicks on and off rapidly (usually in the middle of the night ).
I gather from a quick search on google that some central heating timers have a battery which can wear out and therefore need replacing. Does anyone know if this model has such a replaceable battery. The part number is TH8272. I have opened the device and could not see anything looking like a battery. If not can anyone suggest where I can find a replacement timer unit? I have phoned Ravenheat technical support and they were no help as I am not Corgi registered!!
(unlike the Corgi registered guy who took 4 visits to diagnose a heavily scaled heat exchanger and another 2 visits to replace it - but that rant is for another time)
Please help.
Also, is this a very active site? I do a lot of DIY and would find an active forum very useful. Which DIY forums are useful sources of information.
