DEH 3000 Wiring Diagram
DMP COMP FAN
WARNING: TO AVOID TRANSFORMER DAMAGE ONLY CONNECT WHITE WIRE TO CONTROL IF DAMPER IS USED.
The white wire controls the optional motorized damper that can be installed into a fresh air duct. This provides the ability to control when fresh air is introduced into the building by using the ventilation timer function labeled “DMP” on the control (See Section 3.7). If the motorized damper is not used, DO NOT CONNECT THE WHITE WIRE
TO THE CONTROL OR DAMAGE TO THE TRANSFORMER MAY RESULT. Simply leave the (DMP) terminal unused if the damper is not used, and cap off the white lead fro mthe
5.2C Auxiliary relay operation
At times it may be desirable to coordinate fan operation of the central heating/cooling system with dehumidifier operation. The DEH 3000 features a relay that provides this ability. The relay terminals labeled NC, COM and NO operate according to the following chart:

ON | CLOSED | OPEN |
OFF | OPEN | CLOSED |
Common uses (assuming standard thermostat wiring color schemes as noted):
Disengage A/C during dehumidification Redirect the yellow thermostat wire to the NC terminal. Wire the yellow wire from the A/C to the COM (B) terminal.
Engage A/C during dehumidification
Connect a wire from the “R” terminal on the the thermostat to the “com” terminal on the DEH 3000. Connect a wire from the “NO” terminal on the DEH 3000 to the “Y1” terminal on the thermostat.
5.2D Dehumidifier lockout/activation AC sensor
The control has the ability to activate the dehumidifier or deactivate the dehumidifier when the air conditioner is running.
