Hi all. I have the glow worm 28c gas boiler and the climapro2 thermostat. I have the heating set to come on at different stages of the day. I notice last night when the boiler got up to temperature it knocked of as it should do. I went to use the bathroom a while later and heard the boiler switch on again yet the temperature on the thermostat was still at what I had set it to. So why did the boiler switch on again randomly?

Your boiler has a warm start function which the boiler will occasionally come on to keep it hot for when you need HW you can switch this off if you want, press and hold + and - simultaneously for 3 seconds until ECO shows on the display and that is it turned off
Hi bit of a long shot but did you ever get a solution to this? Mine has started doing it during the current cold snap and I cant find a reason for it...

Could be a frost stat kicking in, could be a fault on the climapro, could be a fault with the time switch if fitted, could be a problem with the diverter valve and warm start if on. All could be , but you haven to given that much to go on.
Its set to come on at 1830 but seems to start rumbling away quitely for an hour at 17:30, the hot water and rad symbols are flashing but it doesnt seem to be heating the rads, then at 18:30 it seems to kick in fully as normal, does that sound like a feature or something wrong with it do you think? Its not a combi boiler. Thanks
