Grounding DISPLAY CODE Dehumidification Options The motor control board has a DHUM or D connection (violet wire) that allows the system to increase the amount of humidity that is removed from the circulating air. See Figure 21 (page 17) This is accomplished by reducing the CFM and allowing the cooling coil to become colder. This will only occur when there is a call for cooling. There are many ways that this can be electrically wired. 1.
