F9.01 is the upper limit of water pressure setting, it is recommended to set F9.29=F9.01,of course you can set F9.01=80%,it needs to be greater than or equal to F9.29. If when the control effect of the inverter is slow or the descent time is too long, try reducing the integration time: F9.06 = 0.5 or 1.0.
