8. Over-current protective control
1) When the over-current protective circuit detected an abnormal current, stop the compressor.
2) The compressor restarts after 2 minutes 30 seconds setting [1] as an error count.
3) When the error count [8] was found, determine an error and restart operation is not performed.
4) For the error display contents, confirm on the check code list.
9. High-pressure release control
1) The operation frequency is controlled to restrain abnormal rising of high pressure by TL sensor in
cooling operation and TC sensor in heating operation.
2) When TL sensor in cooling operation or TC sensor in heating operation detects abnormal temperature of
the stop zone, stop the compressor and the error count b1.
3) When the compressor stopped with 2), the operation restarts from the point of the normal operation
zone (e point or lower) where it returned after 2 minutes 30 seconds.
4) The error count when the compressor stopped with 2) is cleared after the operation continued for
10 minutes.
If the error count becomes [10] without clearing, the error is determined and reactivation is not performed.
5) For the error display contents, confirm on the check code list.

7. Current release value shift control
1) This control purposes to prevent troubles of
the electronic parts such as the compressor
driving elements and the compressor during
cooling operation.
2) The current release control value (
