BaseStation 3200 Advanced Irrigation Controller Manual
To set up concurrent zones for a program
Concurrent zones are the number of zones (valves) that can be operated at the same time –
typically limited by the amount of water available and the design flow of each of the zones. You can
set up the concurrent zones on a per program basis and have it automatically managed using a flow
device. You can also set the total number of concurrent zones for the controller.
In the BaseStation 3200, you manage the number of zones that can run concurrently at the
following levels:
• Mainline Flow Level – When you set up the design flow for the mainline and then set the
Concurrent Zones by Flow field to YES, the system uses the mainline design flow to determine
how many zones can run concurrently up to the program limits. Refer to Setting Up Mainline
Operating Limits on page 68.
• Program Level – If you want a program to water more than one zone at a time, you must
configure the Concurrent Zone settings at the program level.
Even if your system does not have a flow device, you can still use the Concurrent Zone
settings at the program level without having to input design flows for all zones and the
mainline.
When you have one or more flow devices, a good strategy is to set the program concurrency
limits to a reasonable maximum and then decrease specific programs that have some special
considerations (such as, the mainline branch is smaller, longer, or you want to slow the
completion time of a program, or if the two-wire length is very long and you want to control
the voltage drop by limiting the current to those valves).
1. Turn the dial to the Programs position.
2. Press the Next button to select the Concurrent Zones Setup option. The Concurrent Zones
screen displays.
3. In the Program column, press the + or – button to select the program that you want to set up
concurrent zones for.
4. Press the Next button to move to the
Concurrent Zones column, and then press the
+ or – button to change the value in the field.
Note: Consider electrical and water
constraints when you are setting up
concurrent zones.
5. Press the Next button to move to the Total
Allowed field, and then press the + or –
button to change the value in the field. This
field indicates the number of concurrent
zones for all programs added together.
6. When you have finished making changes, turn the dial to the RUN position.
