4.4 CURRENT RELEASE CONTROL
Performed by A3 board
The inverter frequency is controlled so that the current value for the inverter compressor is less than the value listed
in the table below.
This current release control is required in order to prevent abnormal temperature increases in the inverter circuit
located within the electrical box and avoid HIC board damages.
The limited values of the primary current are modified in accordance with outdoor air temperature (T
O
).

Note: The limited values are lowered when the outdoor air temperature is higher than 40°C in the cooling mode and
higher than 14°C in the heating mode.
4.5 COOLING HIGH-LOAD CONTROL
Performed by A3 board
This control is performed to limit the inverter frequency in order to restrict abnormal increases in pressure and high-
load operations in the cooling mode.
In accordance with the temperature of the outdoor heat exchanger temperature sensors (C1, C2), such controls are
performed as decreasing the inverter frequency and restricting its increase, etc.
If the temperature max (C1, C2) exceeds 64°C, operations are halted and then restarted 3 minutes later. If this
start/stop activity is repeated 10 times consecutively, alarm "P20" (cooling high-load error) occurs.
