Any suggestions on which Thermostat I can use with existing wiring. I will be replaceing the standard thermostst that came with the house 4 years old.
AC & gas forced air. I can not run another wire over to it. So I need to use what's all ready in place. I don't want to use an x10 type , rs422 or 232 is fine
but would need one with a controler box that can mount back at the HAVC and comunicate with the thermostat with the existing wiring.
O of corce it need to work with HS old 1.7 and 2ver.
ANY ideas?
