DANGER
The wrong programming of the electronic control could cause big damages to the unit.
The parameters can be modified by specialized personnel only.

The values of the probes can be displayed using a measurement system other than the manufacturer's factory setting. This operation does not
automatically convert the parameter values, which retain the measurement unit set by the manufacturer. To change the measurement unit
