4.4 Automatic and Manual Mode
When there is a failure preset by the system, the fault light will continue to light up
and the display screen will display the fault code. When the failure is eliminated, the
indicator light will go out automatically and the display screen will restore the
real-time pressure valueautomatically.
again. The detection time is 1 hour, 2 hours, 4 hours and 8 hours. If the water
shortage continues, the detection time is 8 hours.
When there is water detected, the pump will start automatically.
When there is leakage in the pipeline, the indicator light will continue to light up;
After the leakage is eliminated or the faucet is opened, the indicator light will go
outautomatically ; The indicator light with leakage does not affect the normal water
use;
4.3.1 When the inverter is electrified for the first time, the default operation mode
isautomatic, and the inverter starts automatically.
4.4.1 The automatic mode is constant pressure and frequency conversion water supply
mode. According to different water consumption, the system will automatically
adjust the pump operating frequency to keep the pump outlet pressure at the set
pressure value. If the water consumption is 0, the system will automatically stop to
save energy. This method can supply water continuously and stably without human
intervention.
4.3.2Pressor or to adjust the set pressure. Short press once, the display showing
real-time pressure value is switched to the set pressure value. Meanwhile the set
pressure value is flashing.Press the regulation button to adjust the working
pressure value. The minimum adjustment amount is 0.1kgf/cm². After adjustment,
the set working pressure flashes for 5 seconds, then exits and switches to the
real-time pressure display;
The pressure value can be calculated according to the following methods:
P - set pressure
H—vertical height from the pump outlet to the highest water point(m);
P=H/10+1.0kgf/cm²;
Note: conversion of pressure and head:1.0kgf/cm² ≈ 10m
Set pressure at 3.0kgf /cm
Starting pressure at 2.5kgf /cm

4.4.2 Manual mode is a working mode designed for failure of sensor. In other words,
when automatic constant pressure water supply is not available, it can be switched
to manual mode and the pump speed can be adjusted by pressing or
manually to realize continuous water supply in case of sensor failure.
Note: in manual mode, when the system is powered on again after power failure, it will
operate fromprevious working state before power failure.
4.4.3 Switch between automatic and manual mode
Short press the button to stop the inverter, then long press the button to
switch between automatic and manual mode:
When switching to automatic mode, the screen displays real-time pressure; When
switching to manual mode, the screen displays the real-time speed.
After mode switching, the system is shut down. Press the button to start the
water pump.
4.5 Parameter Setting
Long press and at the same timeto enter the parameter setting, press or
to adjust the parameter. Short press to enter the parameter value adjustment, press
or to adjust the parameter value.Short press again to save and return.Short
press to return and do not save the parameter value.
