I replaced a trane heat pump tsat (Tempcon 602) and i am now blowing transformers. It is going to a dual fuel kit tayplus 103a. I was able to match up the wires correctly except for one the T wire, there is not one for the new stat i thought is matched up to the F wire, becaues the T wire and the F wire were matched on the tstst install driections. The a/c and heat pump is working but the emheat is were the amps on the 24v spiking. any ideas

thanks
Dave
