Got me a wefe thermostat. Old thermostat used 4 wires but the blue C was stuffed in the wall. I have read many forums and nobodys setup really matches mine.
This what I see at the furnace and what I think the functions are. I see the spot for C but it has a red and yellow wire connected to it. I figured T would be the common but when I hooked the blue wire to this I got power to my new thermostat and could make the fan come on but the A/C would not turn on. Guess my only question being is where to put the darn C wire. Any help would be greatly appreciated!
Here is the old tstat and setup in the furnace. I cannot see a model anywhere on it. Just says climatrol. It is an older one tho with a pilot I gotta light manually.
Here is the wifi stat setup.
I turned it back on and afew minutes later while uploading this pic it the system came on!!! Musta took 3 to 5 minutes but its working! Will make sure it does what it is suppose to do but thank you for advice on waiting and the other help you provided. I really appreciate it!!!

T is common, confirmed by reading 24VAC across T and V (24VAC should also exist across V and ground to confirm V as hot). A/C may need a few minutes to kick on.
