hi wonder if any one can help please. last night heating stayed on all night despite being on timer. temp currently showing 22.5 despite lowering thermostat to 18 heating remains constantly on. i checked relay box in garage no led flashing. i have carried out communication test and green led light flashes. tried to re bind boxes whole process seems to be fine but then final led light does not show on relay box. whole system is only 18 mnths old!! batteries in thermostat were replaced recently. not sure if i have to look at resetting parameters? any help would be much appreciated as although heating is on i am getting worried about heating costs and a bit hot!!! i tried to manually overide relay but this does not stay on for very long
many thanks
