What can I replace this heating controller with? I need a fairly simple solution to tide me over for 6 months. but the price of a replacement 3022 is ridiculous £65+ and locally I've been quoted £82 inc vat.
COntact Randall. I can't remember what they call it but you can get the guts of the thing without the mounting plate and case, or similar, which is a lot cheaper. Something like a "Service Replacement Unit".
