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:

2.3 Auxiliary relay operation

It may be desirable to coordinate fan operation of the central heating/cooling system with dehumidifier 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:

Common uses (assuming standard thermostat wiring colors as noted):

Lock-out the A/C during dehumidification

This will turn off the A/C whenever the dehumidifier runs.
