WARNING!
UNPLUG THE ULTRA-AIRE
DEHUMIDIFIER BEFORE WIRING THE DEH 3000R.
The installer must supply all field wiring, including the
wiring between the Ultra-Aire dehumidifier and the DEH
3000R. Some of the control wires leaving the Ultra-Aire may
not be used in some control situations and should be left
disconnected with wire nuts taped onto the stripped ends.

The White wire controls the optional motorized damper
that can be installed into a fresh air duct. This damper
provides the ability to control fresh air ventilation using
the ventilation timer function of the DEH 3000R and
the terminal labeled
that can be installed into a fresh air duct. This damper
provides the ability to control fresh air ventilation using
the ventilation timer function of the DEH 3000R and
the terminal labeled
“DMP” on the DEH 3000R (See
Section 3.8). Leave the
“DMP” terminal unused if a
motorized damper is not used, and cap off the White
wire from the Ultra-Aire dehumidifier.
