Honeywell CM907 unexpected starting (split off from old thread)

I’ve got a similar problem to this, but the issue is that thermostat clicks on and calls for heat even when the room temperature is above the set temperature, turning off again a few mins later. Not noticeable during the day, but the click and firing up of the boiler is irritating during the night, never mind the wasted gas

What's the set temperature overnight, and the room temperature at the time of it calling for heat?

As this post is over 12 years old, you might want to start your own post, most of us have slept since then

I reset it at 18 last night & it was clicking on at 22
