Hi My Drayton wireless thermostat needed new batteries, which i changed, but since then although thermostat is working, boiler is working, and timer comes on and off, I have no heating. It is as if the thermostat is not "talking to the boiler/timer? But all seem to be working independently of each other? Any ideas please?!! Thank you.
thanks for your reply but i cancelled my question this afternoon as the boiler started working earlier, it took about 24 hours which is why i sent the question. Thanks anyway.
