3.2.20 Protection Control by Overall Current
Monitors the overall current and restricts the upper limit compressor operating frequency to
prevent circuit breakers from exceeding the rated capacity.
Upper limit current (A)
Takes the following values depending on the outside temperature.
Also varies depending on model.
3.2.21 Freeze-up Prevention Control
The thermostat turns OFF due to indoor unit heat exchanger temperature in order to avoid
formation of ice on the indoor unit heat exchanger.
(For details, refer to "Freeze-up Prevention Control".)
3.2.22 Shortage of Refrigerant Detection Control
When judged that the deficiency in performance has been caused by the shortage of refrigerant,
the abnormal stop is activated with the error code "
3.2.23 Piping and Wiring Incompatibility Detection Control
When the connecting pipe and the transmission connecting line are connected each to a
differing outdoor unit, the abnormal stop is activated with the error code "
the remote controller.
3.2.24 Oil Recovery Operation
When the compressor runs at low frequency for a long time, the failure of recovering oil may
cause the shortage of oil level. Therefore, the oil recovery operation is performed by increasing
the compressor operation frequency for five minutes.
* The more the unit operates at low frequency, the higher the frequency of oil recovery
