Hello Folks, I would like to replace my old thermostat (Eberle Lifestyle 15015.3521) which seems to have a low temperature accuracy with a digital one (perhaps the Honeywell DT90, any suggestions?). I was wondering if someone could help me with the wiring. The old thermostat has 4 wires (see photos), whilst the ones on the market now seem to have two wires generally. I know that one of the wires is mains (using voltmeter), and the third is earth, but the other two seem to be both netural. Do you know which ones I would need to connect if I was to fit a 2 wire thermostat?
