Aube Thermostat Compatibility (Wires TH, TH)


I ran the compatibility checker with a wiring configuration and the tool reported that ecobee needs to take a closer look. Can you please let me know if my system configuration is supported?

My thermostat has the following wires: T, T 


The ecobee requires a C (Common) wire in order for the thermostat to receive constant 24VAC power. Typically a 3rd conductor wire is needed that can be used as the C-wire from the thermostat location to your furnace control. However there is a product called "Common-Maker" from FAST-STAT that will allow you to use your existing 2-wires without having to run a new C-wire.
