THE SMART SOLUTION FOR ENERGY EFFICIENCY
Constant Volume ECM Control, Cont’d.
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) AND a humidistat is connected to terminal
DH, the cooling airow will only be reduced when the
humidistat senses that additional dehumidication is
required. The DH 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.
