Humidity Control
When using a Humidistat (normally closed), cut jumper PJ6
on the control board. The Humidistat will only affect both low
stage and high stage cooling airflow by adjusting the Airflow
to 85%.

Two Stage Heating
When using staged electric heat, cut jumper PJ4 on the con-
trol board.

Thermostat Wiring
Use thermostat wiring diagrams provided with the thermostat
when making these connections.

See Specification Sheet for APH model series for CFM vs
ESP tables.
