a) This is your unit's operating pressure. This is also
stamped on the compressor's name plate.
b) To protect the compressor stage, the compressor
only starts up when the compressor's internal
pressure is less than or equal to the set value. If the
compressor's internal pressure is higher when
starting up, the following appears in the display's
third row:
