Honeywell Thermostat Help Please

[ruggief]

Hi I have just moved house and can't make sense of the system. Before I go to the expense of an engineer fallout on a weekend thought I'd try here.

I have a wireless relay in the hall and a thermostat. All radiators bar one have tvrs set to 4 or 5. Boiler is working firing on but radiators won't turn on. I've whacked thermostat right up over 20 as it's currently showing 13.5 degrees (yes I'm cold) but nothing will work. I've tried repairing and rebinding devices per troubleshooting tips and they are paired.

Any advice please?

Thanks teacake that's good advice. Thank you all who responded you've been quite marvellous. Only wish one of you lived next door and could pop over and fix it!

If you are paying £1000 to repair an old boiler, a new system is not much more than that.
You can buy a good quality brand new boiler, say a Worcester Borsh and get a 5 year warranty.

"a new system is not much more than that."

Not at British Gas prices!
