* Also realised via a separate fl oat switch for increased
operational reliability.
A level sensor or a dynamic pressure bell can be
connected to the switchgear, whereby up to
8 switching points can be defi ned for controlling
a maximum of 3 pumps:
• Pump 1 On/Off
• Pump 2 On/Off
• Pump 3 On/Off
• Dry-running level
• High water level
7.2.2. "Fill" operating mode
The reservoir is fi lled up, for instance, to pump
water out of a well into a rainwater storage tank.
The connected pumps are activated when the
level falls and switched off when the level rises.
This control is mainly used for water supply.

Up to 5 fl oat switches can be connected to
the switchgear for controlling a maximum of
2 pumps:
• Pump 1 ON
• Pump 2 ON
• Pump 1 and 2 OFF
• Low water level in the tank to be fi lled
• High water level
• Dry-running level in the well (realised via a
