icon flashes if there are alarms when the machine is off.
- Icons 1,2: identify the state of the individual compressors. If on, the compressor is
functioning, otherwise it is off. The flashing indicates that the compressor has been stopped
for a pressure switch intervention (HIGH or LOW pressure alarm).
