(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).
Setting the value of parameter b0 in the range from 0 to 255 (default 7) changes the humidifier 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 humidifier tank is emptied; CLOSED = standby full, the NO
valve remains powered, keeping the humidifier tank full during standby;
