a second time, and you will hear one beep as the
machine shuts down. Specially note that there
is a one minute fan delay from button push to
shutdown. In addition, the dehumidifier, once
configured for operation, will automatically return to
that mode during power glitch or outage.
If the dehumidifier is switched ON and then put
into Remote/Whole-House Mode, the unit cannot
be turned off with the switch. If in the Remote/
Whole-House Mode and you want to turn the main
power off, then switch the dehumidifier into Unit/
Standalone Mode that re-arms the OFF switch
(both mode indicator lamps off). Thereafter, the
power switch can be used to switch OFF.

Use the Up and Down arrow buttons to set the
humidity set point on the display screen, when

Conversely, when the indoor humidity is higher
than the set point, the button is pushed and the unit
will switch ON to run.
