SPECIAL FEATURES

the on/off function of the dehumidifier units, but is factory pre-set at 55% RH
to maintain the relative humidity air at the set point.

humidity of the air within the room has risen above a warning level due to a
fault, either with the dehumidifier or due to some other circumstances and will
require a service engineer.
