The "relays/controls" menu

"alternate"
Specifies if the pump should be included in the alternating pump control.
Selection
• no (default)
The pump is not included in the alternating pump control. Instead, it switches according to its
own switch points.
• yes
The pump is included in the alternating pump control.
"degree of use"
(for "load control" = "time of use" or "starts")
Defines the desired degree of use (percentage) of this pump for an alternating pump control. The
degree of use is only obtained, if the pump has been allocated to the alternating pump control.
!
Note!
The total degree of use of all pumps participating in the alternating pump control should be 100%.
"maximum use time"
(for "load control" = "starts+time)
Defines the maximum use time for this pump which is valid for the alternating pump control and
for "laod control" = "starts+time". After it has been running for this time, the pump is automatically
replaced by another pump.
"crust reduction"
Specifies a range of inaccuracy (percentage of the measuring range) for the switching points of the
pump. If this value is larger than "0", the switching points are not exactly constant. Instead, they
vary within the specified range of inaccuracy.
This helps to avoid crust formation, which often occurs at fixed switching points.
