Protection Control SiUS281117
Function and Control 47
4.4 Inverter Protection Control
Tb: Outdoor unit heat exchanger temperature
Tfin: Radiation fin temperature
Inverter current protection control and radiation fin temperature control are performed to prevent
tripping due to an error, or transient inverter overcurrent, and radiation fin temperature increase.
