(i) Starting conditions
1)
When 5 minutes have elapsed after the compressor ON or the completion of the defrost control
2)
Other than the defrost control
3)
When, after meeting the conditions of 1) and 2) above, the compressor speed, indoor air temperature (Th1) and indoor
heat exchanger temperature (Th2) have met the conditions in the following table for 5 minutes:
Operation mode
Cooling
Heating
Note (1) Except that the fan speed is HI in heating operation and silent mode control.
(ii) Contents of control
1)
When the conditions of (i) above are met, the compressor stops.
2)
Error stop occurs when the compressor has stopped 3 times within 60 minutes.
(iii) Resetting condition
When the compressor has been turned OFF
(s) Service valve (gas side) closing operation
(i) Starting conditions
1) Operation mode : Heating
2) Compressor conditions : OFF
(ii) Contents control
If the output current of inverter exceeds the specifications, it makes the compressor stopping.
(iii) Anomalous stop control
1) If the inverter output current value exceeds the setting value within 80 seconds the compressor stops.
2) After 3-minute delay, the compressor restarts, but if this anomaly occurs 2 times within 20 minute after the initial
detection.
