Discharge Temperature Release Control
1) This function controls the operation frequency, that is, lowers the operation frequency when the discharge temperature has
rapidly risen during PMV control. It subdivides the frequency control up to a unit of 0.6Hz to stabilize the cycle.
2) When the discharge temperature is detected in an abnormal stop zone, the unit stops the compressor and restarts after 2
minutes 30 seconds. The alarm counter is cleared when it has continued the operation for 10 minutes.
If the abnormal stop zone has been detected by 4 times without clearing the counter, an alarm “74” is displayed.
