Quest DEH 3000 Installation, Operation and Maintenance Instructions Unit Green Yellow 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. 1. W ire the Yellow thermostat terminal to the NC terminal on the Quest DEH 3000. The installer must supply the Unit Green wiring between the Quest dehumidifier and the control panel. Be sure to safely route the control wires to prevent Yellow damage during installation. Be careful not to cross the wires when connecting the Quest dehumidifier and the remote control panel or damage to the transformer may result. 2. R un the Yellow wire from the A/C unit to the COM terminal on the Quest DEH 3000. Energize the A/C central fan during dehumidifier fan...
TO A/C Quest DEH 3000 Installation, Operation and Maintenance Instructions Deactivate dehumidification when the air-conditioner is running. 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-out dehumidifier function. 1. T he common wire from the existing A/C transformer (usually Black) must be attached to the “COM” sensor terminal between “ON-D” TO A/C and “OFF-D” on the DEH 3000. TIP: The common wire can be identified as the wire from the A/C transformer that reads 0 volts between it and the Yellow air conditioning call for cooling wire.

Quest DEH 3000 Installation, Operation and Maintenance Instructions FOR INSTALLER & OWNER: 3. Operation 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. This extends the life of the dehumidifier. When a flashing “O” is encountered, the unit is in wait mode and IT COULD BE UP TO 10 MINUTES BEFORE OPERATION RESUMES. 3.1 Display • W henever there is power to the control, it will display the time, the day, % relative humidity, and temperature.
Quest DEH 3000 Installation, Operation and Maintenance Instructions 3.4 On/Off and display items Press the “ON/OFF” button to turn the system ON or OFF. When the system is ON, the setpoint, fan status, operation mode (RUN or HOLD), and fresh air vent status is displayed. When the system is OFF, the control will display the time, day, %RH, and temperature. When the unit is shipped, it is in manual (hold) mode. 3.5 Setting Clock Time 1. P ress and hold the “CLOCK” button. The hour display will flash. Release the button. 2. U se the up/down “RH” buttons to change the value. 3. P ress the “CLOCK” button again and the minute display will flash. Use the “RH” buttons to change the value. 4. P ress the “CLOCK” button again and AM or PM will flash. Use the “RH” buttons to change the value. 5. P ress the “CLOCK” button again and the day display will flash. Use the “RH” buttons to change the value.
Quest DEH 3000 Installation, Operation and Maintenance Instructions 3.7 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 Quest 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. “AUTO” – Indicates the fan will run when the Quest DEH 3000 calls for dehumidification or ventilation. If the control has not called for dehumidification for 3 hours, the control will automatically run the dehumidifier fan for 10 minutes. After a dehumidification cycle, the fan automatically shuts off for 10 minutes. This pause allows the water to drain from the dehumidifier. A solid “O” indicates the fan is operating. A flashing “O” indicates the fan is in a wait mode. No “O” indicates the fan is OFF. To set the operation: 1. P ress and hold the “FAN” button. The current fan setting will begin to flash on the display. Release the button. 2. P ress the “FAN” button to toggle between the “ON” and “AUTO” modes. With the fan in the “AUTO” mode, the fan will operate only when needed by other functions of the system. The fan will remain OFF unless the system is dehumidifying or ventilating. The fan always runs during dehumidification and ventilation and the fan “O” icon will be lit. To completely turn the system OFF, use the “ON/OFF” button as described earlier. 3.8 Damper Operation and Ventilation, Manual (Hold) Mode The “VENT” setting controls the ventilation function of the system. It has no control over the dehumidification...

Quest DEH 3000 Installation, Operation and Maintenance Instructions 1. P ress the “VENT” button. The current setting will begin to flash on the display. Release the button. 2. P ress the “VENT” button again to switch between “OPEN” and “CLOSED”. 3. L eave the control alone for 10 seconds and your settings will be saved. 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 Quest DEH 3000 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. There are two programs available for ventilation: 1. Monday through Sunday 2. Monday through Friday & Saturday/Sunday Each block of days has a morning schedule and a night schedule. Morning is the first 12 hours of the day and night is the second 12 hours. Each schedule has: • A “START” time when the ventilation schedule begins, • A n “OPEN FOR” duration for the amount of time the damper stays open in 5 minute intervals, from 0 to 60, • A nd “CLOSED FOR” duration which closes the damper for a specified time in 5 minute intervals from 0 to 60.

Quest DEH 3000 Installation, Operation and Maintenance Instructions You can select from: “MON-FRI” “SAT-SUN” for separate weekday and weekend schedules, or “MON-SUN” which gives you equal weekday and weekend schedules. 3. Using the Up/Down “RH” buttons, highlight and then select one of the two choices. The example given shows how to program separate weekday and weekend schedules. The same method is used if you choose the other program. Example: menu when you select “MON-FRI” “SAT-SUN”: 1. E nter the starting time for weekdays using the up/down “RH” buttons to change the time. 2. P ress 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. P ress the “PROGRAM ENTER” button to switch to the “CLOSED FOR” setting. Using the up/down “RH” buttons, change the duration that the damper will remain closed between ventilation cycles. For the example given, starting at 8:00AM in the morning, the control will ventilate fresh air for 15 minutes then stop for 15 minutes. This schedule of 15 minutes open, 15 minutes closed will continue until the start time of the night schedule. Morning schedule is available anytime from 12:00AM until 11:59AM. Night schedule is available anytime from 12:00PM until 11:59PM. 4. P ress “PROGRAM ENTER” again to go to the “MON-FRI” night schedule. Repeat the steps listed above for this and the “SAT-SUN” day and night schedules. When you have finished programming your schedule (either the 7-day version or the weekday/weekend split version), use the down “RH” button to highlight the EXIT option and then press “PROGRAM ENTER” to select it.
Quest DEH 3000 Installation, Operation and Maintenance Instructions 4.0 Temperature Cutout Programming Dehumidifiers produce heat when dehumidifying and depending upon outside conditions, the ventilation function may also introduce warm air. Some conditions may introduce enough heat to drive temperatures up. The Quest DEH 3000 temperature cutout feature disables all Quest operations if temperatures reach the cutout setpoint. In most installations this feature will not need to be used (the cutout is factory set to 99°F). If a lower temperature cutout is desired, program the setpoint by pressing and holding the “PROGRAM ENTER” button until the “PROGRAM” screen appears. Press the up/down “RH” buttons until “TEMP CUTOUT” highlighted. Then press the “PROGRAM ENTER” button again to select it. Now use the “RH” up or “RH” down buttons to adjust the setpoint. Press “PROGRAM ENTER” to return to the home screen. quest quest 1-800-533-7533 www.QuestProtect.com sales@questprotect.com...
