Current Release Control - Fujitsu AOYG45LAT8 User Manual

4. CURRENT RELEASE CONTROL

The compressor speed is controlled so that the outdoor unit input current does not exceeds
the current limit value is decided by the outdoor temperature.
When "ECONOMY OPERATION" or "PEAK CUT OPERATION" are effective,
the outdoor unit will operate by lowest current.
When the outdoor unit input current reaches to the control value, the compressor speed
-1rps every 1 second till the release value.
Then, if the compressor operates at minimum speed and the input current doesn't reach
to the release value, the compressor is stopped.
