7.2 Servicemessages and war-
nings
Service messages and warnings are shown
on the main screen in place of the HygroMa-
tik logo, when the cause has occured. When
tipping the display field, the unit info screen is
shown with the messages in plain text.
The sensivity threshold of the last three warn-
ing messages is set to the highest level ex
factory. Should the on-site conditions (e.g.
the water conductivity) lead to an unwanted
frequent occurence of the messages, the
sensivity can be reduced in the „Service“
submenu (s. section 6.8.4).
