I have a 5 zone split level house with forced hot water heat. The issue I’m running into is that my house has an in-law apartment that I rent out and it occupies 2 of the 5 zones, and the other 3 are divided between my living room, bedroom and basement. The master thermostat is in my living room, and unfortunately that thermostat’s setting dictates the max temperature the rest of the thermostats can go to. I like the house around 60, and my tenant likes it around 70. We agreed to meet in the middle at 65, but unfortunately that means my boiler is heating half of my house to 65 keep her apartment comfortable because the heat needs to be set higher (raising my fuel bill); not to mention the fact that I’m uncomfortable half the time because I’m too hot. My question is whether or not I can move the master thermostat into the apartment easily, if there is a thermostat out there that will allow each zone total control over the max temperature it can be set to, or if there is a simple work around to my issue. As a side note; all 3 zones in my side of the house have digital LUX thermostats, and the apartment still has the old “turn face style” analog ones.
