NOTES:If 10-wires between the Air Handler and the Heat Pump is not possible W1 and W2 can be combined at the AHwith a jumper eliminating W2 out and staged electric heat. X/L can be eliminated as the fault codes can be retrived from the board.
Please call for more detailed instructions if the number of wires is an issue.
