Is this compatible (t wires?)

[onysablet]

Attached is a picture of my current thermostat wiring. I have every wire compatible accounted for other than the far left 2 "t" wires. What do I do with them if they are compatible?

Hi onysablet,

Thanks for reaching out. I'd love to know more about this and I have a few questions:

• What's the make and model of your current thermostat?
• Could you share the labels of the connectors of your thermostat?

Looking forward to your response.

Thanks,

Edward

Hello and sorry for the slow response. When I get home tonight I will get the make and model of the current thermostat as well as the labels for each of the current wires.

Hi onysablet,

Thanks for the response. It looks like your current thermostat is using proprietary terminals. Could you also check the control board of your HVAC system and check where the other end of the wires are connected to?

Thanks,

Edward
