3.6 Adjusting the relative humidity “SETPOINT”
The Quest DEH 3000 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).
