Increase or decrease in pump function ---- constant pressure water supply for two control another lift frequency pump start and stop;
Built-in PID function - inverter according to the feedback signal to automatically adjust the output of the inverter, to constant pressure, constant temperature, constant purpose.
Sleep wake-up function --- Inverter in PID closed-loop regulation does not affect the constant pressure water supply: "Sleep value by the feedback value exceeds the maximum water pressure to start automatically shut down when the water pressure is higher than the upper limit of the inverter; "wake-up value" by the feedback value of the minimum water pressure start, the drive automatically starts running when the water supply pressure is below the lower limit.
Comes with a drag and a few control panel, easy to achieve a drag a few functions, You can drag seven.
