light up. The necessary quantity of liquid then is in the tempering system.
9. If the minimum level liquid remains under, a low level alarm E01 can be caused.
By a short switching-off and switching-on again at the mains switch (1) the alarm
status is cancelled.

until two or
three segments of the level indication lighten.
