We are currently having a (gas) central heating system installed in the church hall of our Grade 2 Listed Building. Our requirement, from the point of view of controlling it, is the ability to independently run the upper and lower halls at a low temperature when not in use, and increase the temperature of one or both when required. And that needs to be done (in the initial stages) by adjusting times and temperature at the control unit, not by having to go into each hall to adjust the thermostat. In other words the thermostat is set remotely. In the long term, once we have a phone line or perhaps a G4 connection to the internet, we would want to do this setting of time and temperature remotely as the person letting the halls lives a couple of miles away!
What would be good flexible control units that would give this degree of control and future proofing?
