14. Faults
14.1 Fault Management
In the event of a fault, the humidification/cool-
ing is haltet. The relevant display field is then
shown instead of the HygroMatik logo. The
display field shows a warning symbol, the
„Fault“ message and - in paranthesis - the
fault code:
When touching the fault message display
field, the unit info screen opens with the fault
message in plain text and information con-
cerning the unit and its current state.
The majority of fault messages is additionally
accompanied by the flashing of one or more
icons, allowing for a first limitation of the
cause of fault.
