To be able to modify the value on the terminal, the corresponding dipswitches must all be O. To be able to use the value set by the dipswitches again, set one of the dipswitches to
On and power o. 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 rst and second digit).
Setting the value of parameter b0 in the range from 0 to 255 (default 7) changes the humidier operating options as regards the following preferences:
1. Unit of measure of parameter b1 (time between two periodical washing cycles): M = minutes; H = hours;
2. Backup: ON = if two humiSonic units, the secondary unit becomes the backup unit for the main unit, i.e. it starts production only if the main unit has shut down due to an
alarm; OFF = backup function disabled;
3. Position of the drain solenoid valve in standby: OPEN = standby empty, the NO valve is not powered and the humidier tank is emptied; CLOSED = standby full, the NO
valve remains powered, keeping the humidier tank full during standby;
