2 pumps in parallel

CP =   2, RH1 starts both CP1 and CP2, (default setting).
    Can be used even if just CP1 is fitted.

2 pumps, in sequence (special)

CP  =   3, RH1 starts CP1, RH2 starts both CP1 and CP2.

IMAGE 7. SETTING THE CLOCK

The clock must always be reset if power to the humidifier has 
been cut off for around 100 hours or more.

The clock switches automatically between summer/winter time 
according to EU standard.
To change the time, do as follows:
Press arrow down so that the clock time flashes. Press OK.
The date and time will now be displayed.
Use the arrow keys to move the flashing field and change
the relevant value using the + and – keys.
When the date and time are set, press the OK key.

IMAGE 8. TO SET THE INACTIVITY TIME SETTING

The water in the humidifier will be emptied if the humidifier has 
been inactive for a period longer than the preset inactivity time 
(no need for humidification).
When the RH1 input closes, the pump starts up (if the water level 
is not too low). When the RH1 input opens, the pump stops and
a time counter begins counting the time that the humidifier is 
inactive ”Not in operation” and the tray is emptied of water. When 
the RH1 closes again, the time counter is reset to zero, the tray is 
filled with water and the pump starts up.

To change the inactivity time setting, proceed as follows.
Press the arrow-down button to cause the value to flash in
the display. Press the + or – button to change the setting to
the value of your choice. Then press OK.
