This selection allows On Demand Dehumidification when using a dehumidifying thermo-
stat or humidistat connected to the ODD wire (as shown in Figure 17). Nominal airflow is
reduced by a preprogrammed amount to maximize latent removal.
IMPORTANT: A humidistat or dehumidifying thermostat MUST be connected to the ODD ter-
minal when using this setting.
