ACC ‘0 … 52 weeks
Condenser cleaning period.
(With ‘ACC’ = ‘0’ condenser cleaning alarm is disabled).
0
IISM
Switch over method to second parameter set:
NON
NON Second parameter set is excluded (the following parameter will be 'SB').
MAN Second parameter set is activated / deactivated by button 'M'.
