9-2-8. CT (Peak current cut-off control)
This function prevents the circuit breaker or fuse from operating to open the circuit. This function works when
electrical current has increased due to an increase in the cooling / heating load, or to a decrease in the power
supply voltage. In these cases, operation frequency is reduced or operation is interrupted automatically to con-
trol the electrical current for operation.
When the cause of the increase in electrical current is rectified, the system will resume operation in the original
mode.
