NOTES:

1.“Y/Y2” Terminal on air handler control board must be connected for full CFM and applications requiring 60 second blower off delay for SEER enhancement.

2.Remove humidistat jumper on air handler control board.

3.For heat pump applications - set MODE jumper on air handler control board to the HP position.

4.To change quantity of heat during HP defrost cycle - reverse connections at W1 and W2 on air handler control board.
