5.3 Adjustments and menu guidance
Table 5.1 gives an overview of the available measurement points and the associated display formats. Table 5.2 shows a summary
of the displays for the calculated parameters.

5.3.1 Display during start-up
After switch-on, the Solaris R3 control unit goes through a self-testing routine, during which all the display elements and the
adjustment parameters are shown separately. The following testing steps are carried out and the results are displayed for about
2 seconds (Fig. 5-4):
– Immediately after switch-on, the start-up display shows the installed software version and the controller's serial number.
– During first commissioning, the display then shows the language selection page.
– For safety reasons, the functions of the pumps and their operating condition lights can only be checked manually
(see section 5.2.5).
