13.1.5. Compressor Overheating Prevention Control
Instructed frequency for compressor operation will be regulated by compressor discharge temperature. The changes of frequency
are as below figure.
If compressor discharge temperature exceeds 112qC, compressor will be stop, occurs 4 times per 20 minutes, timer LED will be
blinking (“F97” is to be confirmed).
13.1.6. Low Pressure Prevention Control (Gas Leakage Detection)
a. Control start conditions
• For 5 minutes, the compressor continuously operates and outdoor total current is between 0.65A and 1.65A.
• During Cooling and Soft Dry operations:
Indoor suction temperature - indoor piping temperature is below 4qC.
• During Heating operations :
Indoor piping temperature - indoor suction is under 5qC.
b. Control contents
• Compressor stops (and restart after 3 minutes).
• If the conditions above happen 2 times within 20 minutes, the unit will:
- Stop operation
- Timer LED blinks and “F91” indicated.
