Wired 24Volt Thermostat (Olivina & Murrieta (Livermore))

Check whether this will work with your system FIRST. Insteon Model 2441TH. I discovered NOT for millivolt gas wall furnace. So, passing along. Original ND gifter said it worked, replaced by Nest. Handles heater, A/C, Fan, but I read somewhere not suited for heat pumps. Do research FIRST before requesting.
