Thank you. Your question resolved my problem by allowing me to realize my mistake.
Yes 2 wires for the AC, one Y and the other C (giving me 2 Y’s in total). I had the Y for the AC connected to the Wyze adapter which created the problem.
Now both AC wires Y and C are connected directly to the control board and everything seems to be working fine. I still have the other four wires connected to the adapter and 2 C wires now connected to the board (the original and the adapter’s) plus the remaining adapter wires to the board.
