Old furnace has t terminal not c. Seems to be the same as c

[Mister_fix_it]

Basic forced air furnace and A/C maybe from 1980 or earlier. Just finally had a newer circuit board replaced this year and still has no led for test or showing issues. Has a t terminal and no c terminal. So considering this terminal should be 24v to power the thermostat, it works. As designed. Very pleased with wyze! So glad to control from another floor or away from home
