Control Settings
Once the unit is positioned correctly, required duct work attached and the
power supply connected, the fan speeds and temperature control need to be
set correctly.
The fan speed controls are located behind a removable cover, to the right of
the main controls. The controls are numbered 1 to 10, with 10 being the
maximum speed.
The temperature control regulates the temperature of the reactivation airflow
onto the desiccant wheel. The control can be set up to a maximum of 145°C
To adjust the temperature control simply press and hold the UP or DOWN
arrows until the required temperature is selected. Once the required set point
is reached release the buttons and the value is stored.
For normal (efficient) operation the process airflow should be set to 412cfm,
and the regeneration airflow set to 94. Measurements should be taken at the
duct outlets using a suitable instrument.
The temperature setting should be set to 90°C above the ambient
temperature of the area being dehumidified
If high moisture extraction is required it will be necessary to increase both the
process and regeneration airflows. The temperature control setting should
also be increased.
If very low humidity levels are required then the process airflow should be
reduced.
The following table should be used as a guide:
