Apologies if this is the wrong section, but it seemed too general to fit into a specific forum section. My central heating has individual radiator thermostats as well as a 'master' thermostat positioned in the hallway of the house (a large bungalow). The master thermostat went faulty recently and I've bypassed it for the moment. My question is, is there any benefit to be had fitting a 'smart' thermostat? To be honest, I'm not sure why it's set up the way it is - it's how things were when we moved in. It seems to me that the master thermostat is largely redundant, assuming the individual radiator thermostats are set up properly. So the 2nd question is really, is it worth fitting a master thermostat at all? Thanks.
