2.5 Testing

Verify the wiring 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.

After checking the wiring, this short test will confirm proper hook-up.

1.Install front cover of the DEH 3000R; connect the top first, then the bottom.

2.Plug in the Ultra-Aire dehumidifier. The DEH 3000R should power up.

3.Turn the DEH 3000R ON by pressing the “ON/OFF” button.

4.Verify dehumidification operation by adjusting the RH “SETPOINT” to below the “%RH” reading on the display. Use the down “RH” button. Confirm Ultra-Aire fan and compressor operation. Both should be ON now.

Increase the RH “SETPOINT” on the display to well above the “%RH” reading on the display. Press the “RH” up arrow to increase the RH “SETPOINT”.

After running the dehumidifier compressor the DEH 3000R applies a 10 minute restart lockout on all functions. You will have to wait for the restart lockout to expire.

5.Verify FAN-only operation:

a.Check the “VENT” mode on the display, it will either be “CLOSED” or “OPEN”. If it is “CLOSED” go to the next step. If it is “OPEN”, press and hold the “VENT” key until “OPEN” flashes on the display, release the key and then press it one more time. “OPEN” will change to “CLOSED”. Don’t touch the keys for several seconds until it stops flashing.

b.Press and hold the “FAN” button until “AUTO” begins flashing on the display, release it, and then press it again to switch the fan to the “ON” setting.

c.Confirm that the Ultra-Aire fan is ON. Ultra-Aire compressor must be OFF. Ventilation damper (if used) should be CLOSED.

6.Verify optional VENT operation (if electric damper is installed):

a.Press and hold the “FAN” button until “ON” flashes on the display.

b.Release the “FAN” button, then press it again to switch fan operation to “AUTO”.

c.Press and hold the “VENT” button until “CLOSED” flashes on the display.

d. Release the “VENT” button, then press it again to switch vent mode to “OPEN”.

e. Confirm that the Ultra-Aire fan is ON. Ventilation damper is OPEN. Ultra-Aire compressor must be OFF.

f. Press and hold the “VENT” button until the “OPEN” flashes on the display.

g. Release the “VENT” button, then press it again to switch vent mode to “CLOSED”.

WARNING! DO NOT MAKE ANY OTHER CONNECTIONS OR TRANSFORMER DAMAGE MAY RESULT.

7.Verify any additional optional control operations such as fan interlock or A/C lockout.

8.Proceed to the Operation section.
