25-91 Manual Alternation

Option:

Function:

value other than

[0] Off

is set, the

alternation is carried out immediately and
the compressor that is selected with
Manual Alternation is the new variable
speed compressor. After the alternation has
been carried out, the Manual Alternation
parameter is reset to

[0] Off

. If the

parameter is set to the number which
equals the actual variable speed
compressor, the parameter will be reset to
[0] immediately after.
