2) Maximum and Minimum Frequency Control
* There is a case in which the frequency set at maximum and minimum may sometimes decrease in accordance
with ambient temperature and indoor loads.

1) Indoor Air Temperature Control
By the control method, not only the thermostat is switched on and off, as explained section “4-12-3”.
Indoor Air Temperature Control ", but also the frequency of the compressor's inverter is controlled in
accordance with
T and fluctuations in indoor air temperature. Inverter frequency is controlled as follows:
· Maximum and Minimum Frequency
When T is high (not yet reached the temperature set
with the remote controller).
Controlled so that the inverter frequency is increased.
When T is low (approxi1.0 or less in the
cooling mode or approximately -1.0 or more in the
heating mode).
Controlled so that the inverter frequency is decreased
or kept.
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 located within the outdoor
unit's electrical box.
Current release control with primary current : The limited values are modified in accordance with ambient
temperature.
