Inverter Protection Control
Inverter current protection control and radiation fin temperature control are performed to prevent tripping due to
an error, or transient inverter overcurrent, and fin temperature increase.
In the case of multi-outdoor-unit system, each inverter compressor performs these controls in the following
sequence.
Inverter overcurrent protection control
Perform the following control of integrated as well as multi units for each inverter compressor.
Radiation fin temperature control
Perform the following control of integrated as well as multi units for each inverter compressor.
