5.9 ON DEMAND DEHUMIDIFICATION AIRFLOW ADJUSTMENT – ACTIVE
(-)H1V
Use switches 9 & 10 to lower cooling airflow as defined in Figure 29:
IMPORTANT:
Selection A turns off the input of the ODD terminal. DO NOT USE SELEC-
TION A WITH A DEHUMIDIFYING THERMOSTAT OR HUMIDISTAT (refer to Figure 29).
Selection C:
On Demand Dehumidification (See Table 5) – Active
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.
