I am thinking of fitting a CM907 to replace a Honeywell T6620B Thermostat. I would like to be able to communicate with it by phone. Is this possible, and what interfaces are available in UK?
I don't think I can go to CM927 with wireless connection. My boiler is in an outside shed, and I doubt if a wireless signal from the hall would reach it reliably.
