E. COOLING AIRFLOW ADJUSTMENTS
Cooling airflow may be adjusted +10% or –10% from nominal airflow using switches 3 & 4.
Refer to Figure 33 for switch positions to achieve the desired adjustments in airflow.
NOTE: Continuous fan speed is NOT affected by switches 3 & 4.
IMPORTANT: The use of On Demand Dehumidification overrides the cooling airflow adjust-
ments when high humidity is detected by a dehumidifying thermostat or humidistat when con-
nected to the ODD terminal as shown in Figure 28. Refer to the Cooling Mode
Dehumidification section for more information.
