TO CONTACT THE RED OR WHITE WIRES FROM THE QUEST DEHUMIDIFIER, DAMAGE TO THE 24-VOLT TRANSFORMER WILL RESULT. WARNING! THE QUEST DEH 3000R DIGITAL CONTROL OPERATES ON A LOW VOLTAGE CIRCUIT (24 VAC) AND MUST NEVER CONTACT OR BE CONNECTED TO A HIGH VOLTAGE CIRCUIT.
Quest DEH 3000R Installation, Operation and Maintenance Instructions 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 Quest DEH 3000R and the terminal labeled “DMP” (See Section 3.8). Leave the “DMP” terminal unused if a motorized damper is not used, and cap off the White wire from the Quest dehumidifier. Standard wire colors for thermostats are as follows: Description Color Terminal code 24VAC Red Call for Heat White W or W1 Force Fan On Green Compressor Call for Cooling Yellow Y or Y1 2.6 Auxiliary Relay Operation It may be desirable to coordinate fan operation of the central heating/cooling system with dehumidifier fan operation.

TO A/C Quest DEH 3000R 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 3000R. 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.

Troubleshooting: If any functions are not working properly, check the wiring and connections. A voltmeter may be used across terminals to verify voltage. If there is concern about the dehumidifier not operating properly, the leads exiting the QUEST dehumidifier may be connected according to the following chart: Wire connections Operation Yellow & Blue Fan & Compressor Yellow & Green Fan Only WARNING! DO NOT MAKE ANY OTHER CONNECTIONS OR TRANSFORMER DAMAGE MAY RESULT.
Quest DEH 3000R Installation, Operation and Maintenance Instructions • R H and Temperature are displayed in real time. • A solid “O” before the SET POINT, VENT, OR FAN indicates the function is operating. • A flashing “O” before the SET POINT, VENT, OR FAN indicates the unit is in wait mode. 3.2 Setting During the set-up process, if you make a mistake, simply continue. You can always go back to adjust the settings. If you leave the control alone and don’t touch any buttons for 10 seconds, the control will remember any changes made and return to the normal display screen, allowing you to proceed to the next step. 3.3 Personal Settings reference list Please record your settings here.

Quest DEH 3000R Installation, Operation and Maintenance Instructions 3.6 Adjusting the relative humidity “SETPOINT” The Quest DEH 3000R senses the ambient relative humidity (%RH) of the space in which it is located, it comes factory preset to hold 50% relative humidity. The relative humidity “SETPOINT” (desired RH to be maintained) operates the dehumidifier function of the Quest dehumidifier. It has no effect on the optional VENT (fresh air ventilation) or FAN ( air recirculation) functions if they are being used. Operation The standard range that the dehumidifier holds around your “SETPOINT” is 3%. With a setpoint of 50%, the dehumidifier will run until the relative humidity reaches 47%. The dehumidifier will then switch off until the relative humidity reaches 53%. If the setpoint is higher than the ambient relative humidity, the space does not need to be dehumidified so the dehumidifier will not run. Example: Setpoint: 50% RH Current condition: 45% RH –The dehumidifier will be off (no “O” indicator will be displayed). If your setpoint is below the ambient condition, the dehumidifier will be on and “O” will display. Example: Setpoint: 50% RH Current condition: 55% RH –The dehumidifier will be on (“O” displayed). 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...
Quest DEH 3000R Installation, Operation and Maintenance Instructions 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 function. In order to provide ventilation, the motorized damper must be open and the fan must be running. The controller takes care of these two functions automatically so that whenever the damper is open, the fan is running. The ventilation indicator “O” will be displayed whenever the unit is ventilating. The fan operation indicator “O” will also be lit. There are three damper operation modes: 1. “ OPEN” – hold mode: The damper will be open and the dehumidifier fan will be continuously operating to introduce fresh air into the space. Use this mode for continuous fresh air ventilation. The fan is always on when the damper is open. 2. “ CLOSED” – hold mode: The damper will never open, and the dehumidifier will not ventilate. The fan will still operate normally for recirculation and dehumidification. 3. “ PROGRAMMED” mode: The Quest DEH 3000R will operate the motorized damper and the dehumidifier fan according to the programmed ventilation schedule (Section 3.9). The factory preset for the “VENT” setting is “CLOSED”. To set “OPEN” – hold or “CLOSED” – hold ventilation operation: 1. P ress the “VENT” button. The current setting will begin to flash on the display. Release the button.

Quest DEH 3000R Installation, Operation and Maintenance Instructions Setting the Ventilation Program: 1. P ress the “PROGRAM ENTER” button until the following menu appears: 2. U sing the up/down “RH” buttons, highlight “PROGRAM” and select it by pressing the “PROGRAM ENTER” button. The following menu appears: 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”...
Quest DEH 3000R Installation, Operation and Maintenance Instructions 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. Running the Ventilation Program Press and hold the “PROGRAM ENTER” button until the “PROGRAM” screen appears. Use the down “RH” button to highlight “RUN PROGRAM”: Then press “PROGRAM ENTER” to select it. The display will appear as follows: 3.9 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 3000R 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...
