Holywell cm67ng not coming on automatically

Dynamonezden · 30 Sep 2015

Hi,

I have a Holywell Cm67NG thermostat connected to my vokera boiler. The auto program has stopped working correctly in the past week. When I select manual, the boiler comes on so it would seem that the thermo is working remotely however the boiler isn't coming on at the requested times when using the auto program. I have put the temperature up to 29 degrees to see if this helps but still nothing.

Any help would be greatly appreciated!
