We have no central heating working. It was all working fine but suddenly it has stopped! The c/h knob has fell off and i can't get it back on but it was still working.....even with this problem now it doesn't do anything except the hot water.

any suggestions.

Is the radiator symbol in the digital display? Press the 'i' button and tell us what 'S' code shows when you think ch should be on.

no radiator symbol, no s code in display just reads a number i think like 5.107 or something?

The 5 is actually an s,what are the actuall numbers displayed after the s?

aaaah! grrr not at the house think it is 107 then? maybe not best to guess!

Forgot to put,no radiator symbol means no call for heating.

the wall sensor flashes orange but then i dont' get a green light. It use dto work a week ago. i turned it off and it doesnt now? ive turne dthe stat right down and pressed reset etc but still nothing. Don't think its parts just a connection fault maybe?

ps any idea how i get the knob back on? it has a littl ered thing inside but only does up when fully wound clockwise?

Assuming you have a wireless stat/programmer, when you turned it off, it has lost 'communication' with the receiver unit.

You need to follow MI's and re-lock the stat and receiver together again.

Doesn't sound like a boiler problem from here and S107 doesn't exist.

hi thanks for replies. Have checked code which is S.30 so room thermostat no heating demand.

I have put trv's on the rads but it did work with these on before. I do have wireless stat etc but how do i reconfigure as such?

thanks,

I can only suggest follwing the MI's for the stat.

Still can't get know to go back on though!!!!
