7.3. SEASON CHANGEOVER
- For every season change, check that
the functioning limits lie within the
limits.
- Check that the compressor input
current is lower than the maximum
indicated in the technical data
table.
- Check, that in models with three-
phase power supply, that the
compressor noise level is not
abnormal. If this is the case, invert a
phase.
- Make sure that the voltage value
lies within the pre-fixed limits and
that unbalance between the three
phases (three-phase power supply) is
not above 3%.
7.3.1. Season changeover from panel

How to activate season changeover:
Under the On- Off branch it is possible
