SEQUENCE OF OPERATION
The dehumidifier will automatically “sample” the air by
turning on its blower (and the HVAC blower if this option
has been wired – see WIRING INTERNAL CONTROL
above), and measuring the relative humidity (RH) once
every hour. Sampling will also occur when the RH setting
is lowered using the
or buttons on the control.
During sampling, if the RH of the air is above the
setting the dehumidifier, the compressor will turn on.
The compressor, dehumidifier blower and HVAC system
blower (if on) turns off when the RH of the air is 3% RH
below the setting.
