Inspect check valve
•
Change pressure tank
•
Ensure b04.00=1 and setb04.04
1. Outlet pipe leakage
2. Check valve leakage
3. Pressure tank damage
4. EMI

Water level transmitter calibration, b01.06 use to
adjust transducer zero bias;
b01.08 use to calibrate the displayed pressure. When
displayed value is smaller than gauge, decrease
b01.08. When displayed value is bigger than gauge,
increase b01.08
