    Old Lennox Duraglass GII 'T' Terminal?
    Hello!

    This is my first question on this site and I appreciate all who take the time to read it! It means a lot.

    That being said, We have a Lennox Duraglass GII gas furnace that was installed around 1976 or so. I know it's definitely not a modern unit, but the heat exchanger is good, it never has any issues, and the blower cage and motor are maintained regularly. We even had a newer condensing unit added to it about 12 years ago or so.

    Being a lover of gadgets (antique and new), I was considering adding a new thermostat that requires the 'c' or common wire. However, I noticed that the low voltage terminal block in the Lennox has terminals marked r,w,y,g, and t. I understand what r,w,y, and g are for, what is 't'? It looks like it feeds out to the condensing unit. From what I've read, can 't' be used as the common or no?

    Outdoor anticipator is the only use of a T wire that I know of. Which model did you buy?

    Thank you for the reply.I didn't buy anything yet, I have just been pricing things out. Didn't want to make a useless purchase yet!

    I was kind of leaning towards this one, however. Honeywell RTH9580WF.
