Dehumidication Mode Settings: The dehumidication mode setting provides eld selection of humidity control. When
operating in the normal mode, the cooling airow settings are determined by the cooling tap setting above. When
dehumidication is enabled there is a reduction in airow in cooling to increase the moisture removal of the heat pump. Consult
submittal data or specications catalog for the specic unit series and model to correlate speed tap to airow in CFM. The
dehumidication mode can be enabled in two ways.
1. Constant Dehumidication Mode: When the dehumidication mode is selected (via DIP switch or jumper setting), the
ECM motor will operate with a multiplier applied to the cooling CFM settings (approx. 20-25% lower airow). Any time
the unit is running in the cooling mode, it will operate at the lower airow to improve latent capacity. The “DEHUM” LED
will be illuminated at all times. Heating airow is not affected. NOTE: Do not select dehumidication mode if cooling
setting is tap 1.
2. Automatic (Humidistat-controlled) Dehumidication Mode: When the dehumidication mode is selected (via DIP switch
or jumper setting) AND a humidistat is connected to terminal DH (version II) or HUM (version I), the cooling airow will
only be reduced when the humidistat senses that additional dehumidication is required. The DH (or HUM) terminal is
reverse logic. Therefore, a humidistat (not dehumidistat) is required. The “DEHUM” LED will be illuminated only when the
humidistat is calling for dehumidication mode. Heating airow is not affected. NOTE: Do not select dehumidication
mode if cooling setting is tap 1.
