∙ Maximum and Minimum Frequency
The compressor's inverter frequency is controlled in accordance with the model and operation mode.
The maximum and minimum frequencies for each model are shown in the table below.
* There are cases in which frequency is limited with other control functions depending on operational conditions,
so operations are not always carried out in accordance with the maximum frequencies listed below.
The inverter frequency is controlled so that the current value for the inverter compressor is less than the figure
listed in the table below in order to prevent abnormal increases in the inverter circuit included in the electrical
component box of the outdoor unit.
Current release control with primary current : The limited values are modified in accordance with ambient
temperature.
