Hi Leesparkykent
many thanks for that, looks like the relays are shot might be an attempt at fixing the unit first but not sure if anything else is damaged, problem I got is that there is no cylinder stat or room stat, just small probe cables by look of it, thinking & by looking found very interesting silver box under a floor board looks like the 3 port valve. think probes just might be tapped to pipes.
will find out on Wednesday.
temp repair on 23rd December was to get boiler running for hot water & heating but had to rely on the boiler temperature switch for control & the plug socket that system was plugged into.
Wednesday going in with RF room stat, programmer & if possible cylinder stat wiring but if i cant get wiring through to airing cupboard then will use RF cylinder stat also.
then change solar controller over & keep both systems separate to a degree.
lady in the house says unit has worked for her for past 30 years+ no problems.
trouble was when i went to have a look i was the last call as they had changed burner (oil boiler) just in case it was that then a new pump cause they thought it was that, not sure on the MV valve that might be under the floor don't think they got that far.
but i will get heating & water control sorted on Wednesday & then fit solar controller.
had a look for this unit online thinking nice little swap out but due to the age of the system unlikely.
put a picture of time clock for hot water heating boost up this is what i am dealing with home made, shame i did not take a picture of the front cover will do Wednesday.
