Control Functions

Low Pressure Control Method
Compressor capacity is controlled by changing the inverter frequency based on the difference between the low
pressure and set value by adjusting the low pressure to the set value (ON value to OFF value).
However, compressor operation continues even if the low pressure becomes below "OFF value" and finally stops
when the low pressure reaches below the "Lim value".
* Lim value = OFF value - Diff value
For the setting of Diff value, refer to "Low Pressure Setting" of "Setting and Indication".
Short Cycle Prevention Control
After the compressor has been stopped, and even the pressure becomes higher than the "ON value", stopping
continues for the forced stopping time (30 to 180 sec).
