Thermostat “Fan Only” Mode

During Fan Only Operations, the CFM output is 30% of the high stage cooling setting.

CFM Trim Adjust

Minor adjustments can be made through the dip switch com- bination of 7-8. Table 5 shows the switch position for this feature.

NOTE: The airflow will not make the decreasing adjustment in Electric Heat mode.

CFM	Switch 7	Switch 8
+10%	ON	OFF
Normal	OFF	OFF
-15%	OFF	ON
	Table 5

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.
