Operation
Using the Dewpoint Monitor and
Dewpoint Control
Your dryer is equipped with a dewpoint monitor and dewpoint control features.
You can choose to use it as a monitor only device, or to maintain a steady
dewpoint that you select with the dewpoint control. Dewpoint control will vary
the regeneration air temperature to condition the desiccant to the level necessary
to maintain the desired dewpoint.
