*Optional dehumidification humidistat switch contacts open on humidity rise. Notes:

1. “Y” Terminal on Air Handler Control Board must be connected for full CFM and applications requiring 60 second blower off delay for SEER enhancement.

2. Move HUM STAT Jumper on AH Control Board to YES position if Humidistat is used.

3. MODE Jumper on AH control board should be set to A/C for air conditioners.
