Cooling fan control
To prolong the life of the cooling fan and reduce fan noise during running, the cooling fan stops when the
temperature inside the inverter drops below a certain level while the inverter stops. However, since frequent
switching of the cooling fan shortens its life, the cooling fan is kept running for 10 minutes once it is started.
H31 specifies whether to keep running the cooling fan all the time or to control its ON/OFF as organized in
below table:
