5.2E Location

Install the remote control panel in a central area of the structure where it will sense the relative humidity of the structure accurately. Do not install the control panel where it may not accurately sense the relative humidity such as near HVAC supply registers, near exterior doors and windows, or near a pool or spa.

5.2F Testing

After wiring connections have been made, verify connections. First, make sure the white wire from the base unit is not wired directly to the DEH 3000 control. There must be a motorized damper in series with these connections, or the white wire must not be connected to the control. Mis-wiring may result in transformer damage.

After connections have been verified, this short test will confirm proper wiring.

1.Install front cover of control; insert at top first, then bottom.

2.Plug in Ultra-Aire base unit. The control should power up.

3.Turn control on by pressing the ON/OFF button.

4.Engage dehumidification operation by adjusting RH setpoint below ambient conditions.

a.Press RH until RH setpoint is 20%.

b.Verify Ultra-Aire fan and compressor operation.

c.Verify ventilation damper (if used) is closed.

5.Verify fan only operation by disengaging dehumidification and operating fan:

a.Adjust RH setpoint above ambient conditions by pressing and holding RH until set point is 80%.

b.Press fan button, then press again to toggle fan to “ON” setting.

c.Release fan button, then press again to toggle fan to “on” setting until “fan” flashes on display.

d.Verify fan operation of Ultra-Aire. No compressor operation should be noted, and ventilation damper (if used) should be closed.

6.Verify ventilation damper operation (if installed) by disengaging from operation and engaging ventilating operation.

a.Press and hold fan button until “fan” flashes on display.

b.Release “fan” button, then press again to toggle fan operation off.

c.Press and hold “vent” button until “vent” flashes on display.

d.Release “vent” button, then press again until “open” is displayed.

e.Verify Ultra-Aire fan operation and ventilation damper is open, with no compressor operation.

7.If any functions are not working properly, verify wiring and connections. Meters may be used across terminals to verify voltage. If there is a concern about the base unit not operating properly, the leads exiting the base unit may be connected and operation verified according to the following matrix:

Wire connections

Do not test any other connections or transformer damage may result. Refer to the appropriate Ultra-Aire base unit manual for additional information.
