2-8. OPERATIONAL FREQUENCY CONTROL OF OUTDOOR UNIT
1.Outline
The operational frequency is as following:
First, the target operational frequency is set based on the difference between the room temperature and the set tem- perature.
Second, the target operational frequency is regulated by discharge temperature protection, high pressure protection, electric current protection and overload protection and also by the maximum/minimum frequency.
2.Maximum/minimum frequency in each operation mode.
