I am presently in Italy and I am trying to install a CM907 to replace an existing thermostat. I have removed the cover of the old thermostat and there are 3 wires, brown, blue and grey.
Can anyone advise me in what order I connect these to the A,B & C terminals on the CM907. The boiler is a combi Ferroli New Elite boiler if that makes any difference.
Thanks.
