THERMOSTAT “FAN ONLY” MODE

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

CFM TRIM ADJUST

Minor adjustments can be made through the dip switch combination of 7-8. Table 4 shows the switch position for this feature.

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