I switch off heating in the Summer manually, and also switch it on manually in the Winter, however this does not help with a warm patch in Spring or cool patch in Autumn. So it would be nice to automate the heating to switch off in summer and on in Winter. So my thoughts, a STC-1000 thermostat is cheap enough, and it can have the gap between off and on set between 0.3°C and 10°C I am thinking set to about 8°C so if the house cools to 14°C then central heating will switch on, and if it warms to 22°C then it will switch off. Since normal thermostat set to 20°C it should never turn off in Winter. As to where to put probe, and how to house the STC-1000 that needs some thought, but first what about the general idea, would it work, is it worth it, etc.
