SEQUENCE OF OPERATION
Adjust the relative humidity (RH) setting on the dehumidifier control; this will be the
setting for both the Primary and Secondary Zone. Once an hour, the dehumidifier
will “sample” the air in the Primary Zone. If there is no need for dehumidification in
the Primary Zone the dehumidifier will then sample the air in the Secondary Zone.
When sampling in the Primary Zone the dehumidifier will energize the dampers and
then turn on its blower (and the HVAC System blower if wired as shown in
WIRING
INTERNAL CONTROL
above), to measure the RH of the air. If the RH of the air is
above the setting, the compressor will turn on. If the Primary Zone does not need
dehumidification, the dampers are de-energized and the HVAC System Blower (if on)
is turned off while the dehumidifier blower continues to run to sample the air in the
Secondary Zone. If the RH of the air in the Secondary Zone is above the setting, the
compressor will turn on.
