F5:
P-SUCTION START (+)
At set point controlled operation the compressor will start when the suction pressure exceeds the set
point (set point A/F5) by the number of degrees entered.
F4: P-SUCTION
STOP
At set point controlled operation the compressor will stop when the suction pressure falls below the set
point (set point A/F5) by the number of degrees entered.
F3: PROPORTIONAL
ZONE
This value indicates by how many degrees above and below the set point for suction
pressure/brinetemperature, proportional zone control that there will take place. When the pressure is
within the proportional zone of the set point, capacity control will proceed slower the nearer the
pressure comes to the set point for suction pressure (Setp. A, F5) / brinetemperature (Setp.E/F5)
F2:
DEAD BAND ZONE (+/-)
This value indicates by how many degrees above and under the set point for suction pressure /
brinetemperature there will be no regulating action.
