Keston C36 combi - CH not following timers

[Hollie92]

I moved into a flat in August and have been trying to sort my central heating out recently! The boiler was on summer mode when I moved in, I have taken off summer mode and set times when I want heating on the Drayton digitstat RF2 wireless system. The thermostat shows a flame when sending signal to boiler to heat but the boiler seems to just be constantly heating and not folllwing the timers. I set it to turn off at 11pm and come on again at 6.00am which it didn't and has been on all night. I've read manual for both boiler and thermostat and nothing I've done has worked. The CH light on the boiler has been flashing green which according to the boiler manual means the demand is still present but the burner is off because the unit exceeded the desired temperature and the forced anti-cycle delay has not elapsed.
Could someone please help me!

Thank you in advance

Just saw your post (after making my own post about a problem I'm having) and I have the same issue. My keston will not follow a timer for heating. I have to turn it on and off when I require. Probably not much help to you but you're not the only one with this issue!!
