We've just turned the CH back on for the winter. It's controlled by two Drayton Digistat +3s, one in the hall and one on the landing.
Every night since turning it back on, downstairs has been fine (21C) while upstairs has been sweltering (typically a displayed 24C). I've been through the programming on the upstairs Digistat and it's programmed to heat to 21C.
Last night I put the upstairs one into Manual mode (which is supposed to override the programming until you switch back to Auto) and adjusted the temp down from 24C to 21C. When I got up at 5.30am, it was still in Manual, but it was reading 26C, and the bathroom was like a sauna.
The only fix I've been able to find is to switch the CH back off overnight.
Can anyone suggest what's going on?
