To access this menu, the pressure sensor must be enabled (

In case a pressure value other than zero is displayed
despite the absence of pressure inside the circuit
,
it is necessary to perform zero calibration of the sensor.
Before carrying out any operation, disable the pump by disconnecting it from the power
supply.
Make sure that the pump is correctly disabled, then open the main valve and all section
valves.
