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.
Alarm Humidistat
This humidistat, which has been factory pre-set at 70% RH, allows for
connection to an external warning system. This warning indicating system will
be monitored by the customer and will warn and indicate when the relative
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.
