Fan Mode
The Fan mode determines whether the fans in the
dehumidifier shall operate continuously, or they shall
operate only when drying is required and ongoing.
If continuous fan is selected, the CONT is presented in
the lower right corner of the default screen.
If possible, for optimal drying effect, use continuous fan
to keep the air in constant motion.
Intermittent fan mode means that the fans are
deactivated when dehumidification is not required as
dictated by the control mode. The fans will however
start and run for five minutes every hour and it is only
during these five minutes that the machine will check
and read the temperature and relative humidity. If, by
these measurements, dehumidification is again
required the machine will resume dehumidification. If,
on the other hand, the measurements give that
dehumidification is still not required, the fans will stop
and the machine will again remain idle for 55 minutes.
Intermittent fan mode does thus have a potential to
save energy in situations where ducting and positioning
of machine are such that the values provided by the
RHT sensor
by the machine’s inlet ca nnot be trusted
and considered relevant unless the fans are running.
The user should however consider that the intermittent
fan mode in combination with control mode based on
the internal RHT sensor can cause a delay of the
dehumidification of almost an hour when the humidity
rises. If such a delay is not acceptable, it is
recommended to use continuous fan mode or to use an
external RHT sensor.
