    My question about the LUX TX9000TS thermostat is that it would seem that to run the thing on furnace supplied power rather than the batteries I need it to be wired to the furnace with 5 wires but only 4 wires come from any of the furnaces and I did not try to pull wires into walls to get an extra wire from lower level furnace room up to the top level thermostat location. I have 3 furnaces in the house - one for each floor. Since I never use the "FAN" switch on any of the 3 thermostats, why could I not disconnect that wire at the thermostat and at the furnace and use it to bring up the "Common" wire that is needed by the LUX to power the thermostat that way. My assumption is that the fan is operated by a contact within the furnace when it is called for during heating or cooling and that the thermostat fan control is just an additional way the fan is powered on and that I can do this. Is there a schematic diagram of this thermostat since if I had that I could answer my own question. I am a retired electrical engineer.
