I want to replace my old analogue thermostat with my shiny new Honeywell CM907. I thought it would a be a simple job that I could do myself but now I'm not so sure. I have three wires in the old thermostat and I only need two in the new one, as the earth (striped) is not needed. I understand the earth wire needs to be 'made safe' but I'm not sure how to do this.
Should I even be attempting this myself or is it a job for an electrician?
TIA
