We had a recent issue with our heating system after calling an emergency plumber to fix a leak, but that's another story. A reputable plumber came and fixed the issues and the heating worked, but now there seems to be a new issue. The heating comes on at the time it's set to, and gets the house up to temperature, but then once it goes off it doesn't click back on as the temperature dips. However if you switch the control panel on and off at the wall it then kicks in. I assume this means it's an issue with the control panel itself or could it be something else? Boiler is a worcester greenstar Ri, control panel is a boss therm bup2.
