5.3.1 Start display
After switching on, the solar control system carries out a self test where the display elements are switched on individually and
the setting parameters of the user level are displayed. The following test steps are run and displayed in succession for approx.
2 s (Fig 5-7):
– Immediately after switch-on the start screen appears showing the installed software version and the serial number of the
unit.
– At the initial start-up the user is prompted to select the display language.
– The function of the pump and the status indicator can only be checked manually for security reasons (see chapter 5.2.4).
