codes
The error codes listed in the table
can be called up in the display
of the heat pump manager. See Controller ---> Displays --->
System ---> Errors. If an error with
a corresponding code is present,
an error scan can be performed by
pressing the assigned function key.
After a short period of time the 10 most recent faults, including the
date and time, are listed with the
exception of error codes 54 and
55. They are treated as recurring
messages and are not listed in the
error scan.
