5. HIGH PRESSURE PROTECTION
During the compressor operation, when detect the condition of the following table value,
the protection function will be worked.
The operation condition varies according to the compressor speed.
The protection function is, the compressor speed is descreased 7 rps every 60 seconds.
When the outdoor unit discharge pressure sensor rises above 580.2 psi (4 MPa), the
compressor will stop.

6. COMPRESSOR TEMPERATURE PROTECTION
Compressor temperature sensor is monitoring the compressor Temperature 1.
When the compressor temperature sensor detects higher than Temperature 1, the compressor
is stopped.
When 3 minutes has passed from the compressor stop and the compressor temperature sensor
detects lower than Temperature 2, protection is released and compressor will restart.
