5. Control Options
The Quest 215 Dual can be equipped with various accessories to enhance its operation. A remote control must be used
with the Quest 215 Dual. ThermaStor oers the DEH 3000 proprietary controller. The DEH 3000 allows homeowners
the ability to monitor and control relative humidity levels in their home. This control is also oered witha remote sensing
option.
WARNING: DO NOT allow the yellow lead from the unit to contact the red lead or the white
lead from the unit or damage to the transformers will result.
The Quest 215 Dual is controlled using five color-coded wires.
Green (or brown) = Fan control
Blue = Dehumidification (fan and compressor) control
Red = 24volt AC power transformer neutral side (common with white)
White = 24volt AC power transformer neutral side (common with red)
Yellow = transformer high side
Between the red/white lead and the yellow leads is a 40VA transformer. This low voltage power source powers the relay
coils which control the fan and compressors. This 24VAC transformer can also be used to power HVAC assessories
external to the dehumidifier.
• To turn the dehumidifier on make contact between yellow and blue wires.
• To turn the fan on make contact between yellow and green(or brown) wires.
• To power an HVAC accessory, connect the accessory to the white (or red) wire and the yellow wire.
