Ideal isar, 4-5 yrs old replaced the batteries in the wall programmer but it still won't switch up or down, i have to turn it off on the reciever or the boiler switch itself.
I have two spare boilers for parts, can someone point me in the right direction of what to try next? thanks, it seems to be just on the heating side of things.
