PRESSURE SENSOR CALIBRATION

In case of wrong lecture of the pressure sensor it can be
adjusted again.
For the pressure sensor calibration is necessary to have a
pressure gauge in the installation. Proceed following next
steps:
ZERO REGULATION
1. Open the taps living the hydraulic net without pressure.
2. Press simultaneously the buttons
display show 0.0 flashing.
3. Press to validate.
FULL SCALE
1. Start the pump until cut-out of the pressure switch.
2. Press simultaneously the buttons
play flashes with a figure.
3. Adjust the pressure with the arrows push-buttons to get
the pressure desired.
4. Press to validate.
Remark: pressure sensor decalibration should not be
a normal event. If it is frequently repeated contact the
technical service.
