Control mode
You can switch from the performance view to the settings view by pressing the push button. The settings view shows which mode
controls the circulator. After 2 seconds, the display switches back to performance view.
If you press the button for 2 to 10 seconds, the user interface switches to "setting selection" if the user interface is unlocked. You can
change the settings as they appear. The selection of the control mode depends on the system type and the allocation of pressure losses.
If you press the key lock for more than 10 seconds, you can toggle between enabling/disabling the key lock function.
