In the above drawing, the steady light in the
middle column
of the top row, indicates

is -0.1 Bar.
·
By depressing the
SET
key momentarily,
the light in the top panel will move from
the Bar LED to
°
C
Sat
LED. The display
will then show the temperature which
corresponds to the pressure of saturated

will show the alarm limit for low suction
pressure (column

If you then press the
key once and
then the
