Looking for some advice on changing from our existing CM907 thermostat to a 927 wireless version.
Curently the 907 thermostat is on the 2nd floor and controls the 1st and 2nd floor heating. What I want to do is replace the 907 thermostat with the receiver for the 927 to control the temperature in the 1st floor bedromm better.
Is it as simple as re-using the wiring that is already running to the 907 thermostat or does the wireless receiver require different wiring?
