Alarm limit for maximum current in A
Begin of the motor current limitation -
enter value as an offset to the alarm value in A
Begin of the forced decreasment of the capacity due to
high motor current -
A value of 0% disables this function / 100% equals a lineair
relation between motor current and compressor capacity
