SAFETY INSTRUCTIONS READ THE INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS CAREFULLY BEFORE INSTALLING AND OPERATING THIS DEVICE. PROPER ADHERENCE TO THESE INSTRUCTIONS IS ESSENTIAL TO OBTAIN MAXIMUM BENEFIT FROM YOUR ULTRA AIRE WHOLE HOUSE VENTILATING DEHUMIDIFIER. WARNING! THIS SYMBOL MEANS IMPORTANT INSTRUCTIONS. FAILURE TO HEED THEM CAN RESULT IN SERIOUS INJURY OR DEATH. CAUTION! THIS SYMBOL MEANS IMPORTANT INSTRUCTIONS. FAILURE TO HEED THEM CAN RESULT IN INJURY OR MATERIAL PROPERTY DAMAGE.
INSTALLATION Install the DEH 3000 control or the remote sensor portion of the DEH 3000R in a central area of the structure where it will sense the relative humidity of the structure accurately. Do not install the control panel or remote sensor 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. Install in accordance with all applicable codes and standards. 1.
WIRING WARNING! DO NOT ALLOW THE YELLOW WIRE OR +24V TERMINAL ON THE ULTRA AIRE DEHUMIDIFIER TO COME IN ELECTRICAL CONTACT WITH THE RED/WHITE WIRES OR COM/DMPR TERMINALS ON THE ULTRA AIRE DEHUMIDIFIER OR DAMAGE TO THE 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 3000/R.
WIRING WARNING! ONLY CONNECT THE DMPR TERMINAL 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 3000/R and the terminal labeled “DMP” on the DEH 3000/R (Page 13). Leave the “DMP” terminal unused if a motorized damper is not used.
WIRING Common Uses (assuming standard thermostat wiring colors as noted): Lock-Out the A/C During Dehumidifier Fan Operation (Figure 1) This will turn off the A/C whenever the dehumidifier fan runs. 1. Wire the Yellow thermostat terminal to the NC terminal on the DEH 3000/R. 2. Run the Yellow wire from the A/C unit to the COM terminal on the DEH 3000/R. Energize the A/C Central Fan During Dehumidifier Fan Operation (Figure 2) To automatically run the A/C FAN when the dehumidifier fan runs. 1.
WIRING Dehumidifier Lock-Off or Lock-On A/C Sensor Feature To automatically activate or deactivate the dehumidifier when the air conditioner runs. Activate Dehumidification When the A/C is Running (Figure 3) ON-D COM OFF-D A voltmeter is required for the next steps to ensure the correct wiring from the A/C transformer is used to set up the Lock-On dehumidifier function. 1.
WIRING Testing Verify the wiring connections. WARNING! ONLY CONNECT THE DMPR TERMINAL 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 3000/R; connect the top first, then the bottom. 2. Plug in the Ultra Aire dehumidifier. The DEH 3000/R should power up. 3. Turn the DEH 3000/R ON by pressing the “ON/OFF” button. 4.
WIRING Troubleshooting CAUTION! TROUBLESHOOTING SHOULD BE PERFORMED BY A QUALIFIED HVAC TECHNICIAN. WARNING! ELECTRICAL SHOCK HAZARD. ELECTRICAL POWER MUST BE PRESENT TO PERFORM SOME TESTS. THESE TESTS SHOULD BE PERFORMED BY A QUALIFIED SERVICE PERSON. Symptom Possible Reason No display on initial start up. This is often the result of a drained capacitor. The capacitor will recharge once power is applied or reapplied to the unit. Troubleshooting Procedure 1. Verify unit has power. 2.
OPERATION For Installer and Homeowner: On the display screen, a solid “O” in front of any of the 3 functions (SETPOINT, VENT, FAN) indicates the function is operating. A flashing “O” indicates it is in a wait mode and not available at the moment. No “O” indicates the function is currently OFF. Solid “O” Before Indicates SETPOINT Dehumidifier on VENT Fresh air ventilation cycle in progress FAN Fan on Wait mode is a factory-programmed time period meant to prevent short cycles.
OPERATION Setting Clock Time 1. Press and hold the “CLOCK” button. The hour display will flash. Release the button. 2. Use the up/down “RH” buttons to change the value. 3. Press the “CLOCK” button again and the minute display will flash. Use the “RH” buttons to change the value. 4. Press the “CLOCK” button again and AM or PM will flash. Use the “RH” buttons to change the value. 5. Press the “CLOCK” button again and the day display will flash. Use the “RH” buttons to change the value. 6.
OPERATION Fan Setting and Operation Use the “FAN” button to change the fan operation. There are 2 choices for fan operation: “ON” or “AUTO”. The factory preset is “AUTO”. “ON” –The fan in the Ultra Aire dehumidifier will run continuously. This does not affect either the dehumidification or ventilation functions of the system. The system may or may not be ventilating or dehumidifying while the fan is running. This setting is commonly used for maximum air filtration and/or air recirculation.
OPERATION Damper Operation and Ventilation, Programmed Ventilation This example shows the system in program mode denoted by the schedule 15 minutes on, 5 minutes off and the word “RUN” in the lower right corner of the display. The DEH 3000/R will operate fresh air ventilation according to your ventilation program. The control needs to be programmed to turn the ventilation function ON and OFF at the desired intervals. This is done by programming the ventilation timer.
OPERATION Setting the Ventilation Program (Continued) The display to the right shows the menu when a separate weekday and weekend schedule is selected (“MON-FRI” “SAT-SUN”). 1. Enter the starting time for weekdays using the up/down “RH” buttons to change the time. 2. Press the “PROGRAM ENTER” button to switch to the “OPEN FOR” setting. Using the up/down “RH” buttons, change the duration that the damper will ventilate fresh air. 3.
OPERATION Calibration and Offset In the event the display shows a humidity reading that is different than that in the room, the RH or temperature display can be adjusted to show a value higher or lower. Calibration mode will be entered by simultaneously holding the SET POINT up key and ON/OFF key, then pressing the PROGRAM key for 5 seconds. The RH will flash. It can be adjusted up or down by pressing the SET POINT keys. By pressing the PROGRAM key again, the “TEMPERATURE” starts flashing.
REMOTE SENSOR OPTION This section is applicable only to customers who have purchased a remote sensor package. The standard DEH 3000 controller does not offer remote functionality. WARNING! THE USE OF SPRAY PAINT ON THE SENSOR HOUSING MAY DAMAGE THE SENSOR AND IS NOT COVERED BY THE PRODUCT WARRANTY.
