(1) To be able to modify the value on the terminal, the corresponding dipswitches must all be Off. To be able to use the value set by the dipswitches again, set one of the dipswitches to On
and power off. When powering on again, the controller will use the values set by the dipswitches.
(*) after 999 the display shows
to indicate the 1000s (the three digits are displayed with a dot at the top between the first and second digit).
(**) the default is 0 (zero), for humidifiers without auxiliary card and without humidity/temperature probe.
