Hello Community,I couldn't find information while searching if it was possible to repalce a Saunier Duval ExaControl thermostat by my Nest E.I move to my new place in two weks and would like to swith the alrezdy installed thermostat from Saunier Duva...

Good evening,The only Nest E i installed so far replaced a 2 wire thermostat and it was the same model as on Google tutorial video so it was very easy.  I now have to install another one to replace a classic - no-progam thermostat with 3 wires labels...
