Hi everyone.   I am studying the possibility of using the heat controller in my radiators, but I have a question about control the boiler.   Now, I have a thermostat in my living room with a free potential contact to turn on/off the boiler when the temperature reaches/drops the predefined value.   Do I need to change this thermostat for one compatible with heat controllers? Maybe only with an actuator on/off should be fine...Isn't it? Wich one do you recommend?
