10. Configuration
10.1 Default settings
The pump is supplied from the factory with the
following default settings.
If one or more of the above parameters are to be
changed, use the optional CIU unit together with
an R100 remote control.
The CIU unit can be connected temporarily for
configuration.
For further information, see installation and
operating instructions for the CIU unit.

10.2 Pump alternation
If several pumps (up to four) are installed in the
same tank, the control logic incorporated in the pump
will ensure that the load is distributed evenly among
the pumps over time.
Alternation is carried out according to a patented
method based on measurement of the liquid level in
the tank.
10.3 Start level set
The pump start level may be affected by the
barometric pressure. In the case of long intervals
between start and stop, the start level may differ
from the set level. See examples below.
Example 1: Constant barometric pressure
The pump will start when the liquid level in the tank
has reached the set start level. Then the pump will
run until the liquid level reaches the stop level. When
it stops, the pump will calibrate itself in relation to the
actual barometric pressure. See fig. 8.

Example 1: Constant barometric pressure
Example 2: Rising barometric pressure
If the barometric pressure rises after the pump has
stopped, the pump will register this rise as a rise in
liquid level. The result may be that the pump starts
before the set start level is reached. See fig. 9.
