When the pump operates in night mode, it automa�cally switches between
the selected opera�ng curve in the mode and night curve.When the night
mode is prepared for opera�ng, its icon illuminates and the pump operates
in the selected opera�ng curve of the mode. The control panel shows –C
while running at the se�ng.
