8.2.1.7. Compressor Tank Temperature Rise Protection Control
a. Control start conditions
Control will perform when (1) - (3) condition continues operation for 5 minute and (4) is fulfill.
1. During cooling and dry operation: Frequency more than normal Fc.
Air-temperature: Indoor and outdoor 30±5 degrees C
Remote control Hi; 16 degrees C
During Heating operation: Frequency more than Fh
Air temperature: Indoor and outdoor 20±2 degrees C
Remote control Hi; 30 degrees C
2. Outdoor total current I Air conditioning: 0.65<=I<1.65.
Heating: 0.65<=I<1.65
It is not during deice operation
3. During cooling and dry operation: indoor suction-indoor piping temperature is below 4°C.
During heating operation: Indoor piping temperature-indoor suction is under 5°C.
Control contents:
•
compressor stops (restart after 3 minutes)
•
if happen 2 times within (20 minutes), perform the following operation
1) Unit stop operation
2) Timer LED blink and “F91” indicated
8.2.1.8. Low Frequency Protection Control 1
When the compressor operate at frequency lower than 22 Hz continued for 20 minutes, the operation frequency will be increased
to 22 Hz for two minutes.
8.2.1.9. Low Frequency Protection Control 2
When all the below conditions occur, minimum value (Freq. MIN) for the frequency instructed to compressor will change to 30 Hz
for cooling mode operation and 20 Hz for heating mode operation.
Temperature, T, for: Cooling/Soft Dry Heating
Indoor intake air (°C) T 15 or T 30 —
Outdoor air (°C) T 16 or T 38 T 4 or T 24
Indoor heat exchanger (°C) T 30 T 0
8.2.1.10. Minimum Frequency Protection Control
•
During cooling operation (except Anti Freezing control, soft dry) carry out the following operation.
1. During Remote Control setting is 28°C & below.
