2.2 Wiring
WARNING!
DO NOT ALLOW THE YELLOW
WIRE FROM THE ULTRA-AIRE DEHUMIDIFIER TO CONTACT
THE RED OR WHITE WIRES FROM THE ULTRA-AIRE
DEHUMIDIFIER, DAMAGE TO THE 24-VOLT TRANSFORMER
WILL RESULT.
WARNING!
THE REMOTE CONTROL OF THE
ULTRA-AIRE DEHUMIDIFIER OPERATES ON A LOW VOLTAGE
CIRCUIT (24 VAC) AND MUST NEVER CONTACT OR BE
CONNECTED TO A HIGH VOLTAGE CIRCUIT.
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.
Be sure to consult the electrical schematic in this manual or
the internal electrical box of the Ultra-Aire dehumidifier before
making any control connections.
WARNING!
ONLY CONNECT THE WHITE WIRE
TO THE CONTROL IF IT IS WIRED IN A CIRCUIT THROUGH
AN ELECTRIC DAMPER, OTHERWISE TRANSFORMER
DAMAGE MAY RESULT.
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
“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.
Standard wire colors for thermostats are as follows:
Description
Color
Terminal code
24VAC Red R
Call for Heat
White
W or W1
Force Fan On
Green
G
Compressor
Call for Cooling
Yellow
Y or Y1
2.3 Auxiliary relay operation
It may be desirable to coordinate fan operation of the central
heating/cooling system with dehumidifier fan operation. The
DEH 3000R contains a relay that provides this ability.
The relay terminals labeled NC, COM and NO operate according
to the following chart:

COM to NC

Common uses (assuming standard thermostat wiring colors as
noted):
Lock-out the A/C during dehumidifier fan operation
This will turn off the A/C whenever the dehumidifier fan runs.
