Aube thermostat to Nest 3rd gen

[Frankietuna]

Hi ,

AUBE CT280-2H1C with 2 wires connected to TH conectors in the thermostat upstairs.

In all installation videos im seeing alot of wires but behind mine theres only two ( TH ) red and black.   Does this mean its not compatible ?

thanks

Hello Frankietuna,

Thanks for reaching out! The AUBE CT280-2H1C thermostat typically requires more than just two wires for a standard installation. However, if you only have two wires (red and black) and they are connected to the TH terminals, it might be worth exploring further.

Firstly, confirm the compatibility of your thermostat with your heating and cooling system. Some systems require more wires for specific features, so ensure your thermostat supports your HVAC setup. If your current thermostat setup doesn't seem to match the standard configurations in the Nest Thermostat, please post a picture of it so we can see how the wires are being labeled.

Regards,
Mark
