Sorry yes this is what i meant, i have attached it to 3 and 4, but still not working correctly. If i set the thermostat to low in the mornings, it wont come on. However if i set it to about 55c on the boiler itself, the central heating comes on. It seems its not working if i set the temp to low on the thermostat.
Any ideas what could be wrong? I've tried switching the wires around in the thermostat itself, but same problem. Its a drayton thermostat.
