When working by the actual flow (not by the nominal flow) there is only one delay to
be defined. This delay specifies the time during which the flow is expected to remain
within its new value before a combination change will take place.
The user may specify a Flow Limit, which represents the maximal capacity of the
source, flow demand beyond this limit will not be granted. It will cause programs
with excess demands to wait until earlier programs finish.
A water source may be associated with a real or virtual water meter measuring the
water supplied by the source. The measured water is divided between the valves
open under the source. Therefore, irrigation valves with no water meters can have
their water measured by the meter of the water source.

Satellites
9.2.1
Associating Satellites with other outputs
Satellites are outputs that can be logically attached to other outputs so that
whenever any of those outputs is activated, the satellite will also be activated and
remain active as long as at least one of the leading outputs remains active.
In the screen above, satellite No. 1 is defined as satellite of the pumps 1, 2, and 3 of
water source A, it will be active as long as any of those pumps are active.
Satellite No. 2 is defined as satellite of valves 1 and 2 of line 1, it will remain active
as long as any of those valves is open. Notice that the table above may be longer
than one screen, use the

9.2.2
Conditioned Satellites
Satellites may be condition dependent so that as long as any of the related
conditions is TRUE, the satellite will remain active. For relating conditions with
satellites the row of the condition has to be marked with a + at the column of the
appropriate satellite. For example in the following table satellite No. 1 depends on
conditions No. 1 and No. 2.
