Input Current Control

Outline The microcomputer calculates the input current while the compressor is running, and sets the
frequency upper limit from the input current.
In case of heat pump models, this control which is the upper limit control of the frequency takes
priority over the lower limit of control of four way valve operation compensation.

After 2.5 seconds in this zone, the compressor is stopped.
The upper limit of the compressor frequency is defined as operation frequency – 2 Hz.
After this, the output frequency is lowered by 2 Hz every second until it reaches the keep
zone.
The present maximum frequency goes on.
Limit of the frequency is canceled.
