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 1, 2 and 3. As per picture below.
Is this compatible with Nest E ?
Thanks in advance fir any feedback
