If the plant mode was set to "Plant operation = Off" at the start of commissioning (see Section 3.2.1), it must be reset to "Plant operation = Auto" when commissioning is complete.
When commissioning is complete (e.g. after "Basic settings", see the operating page above), the repeated pressing of the ESC button results in the following warning:
Acknowledge the display of OK by pressing the knob (the plant is started). The display then returns to the main menu.
Plant operation = Auto
Before exiting the main menu, press the knob to open the "Plant operation" page.
Select "Auto" (= enable) on the "Preselection" line and acknowledge by pressing the knob. Press ESC to return to the start page.
