6.13.6 Flow Percentage
The Flow Percentage feature can be used to globally establish station flow upper limits. The flow
percentage can be set from 5 to 80 percent. This feature can be used in two ways:
1. Assume limits need to be established for a new system and you wish to have all station flow
limits to be 15 percent above their nominal value.
Then:
• Set the flow percentage to 15 percent.
• Run Automatic LIMITS (see next section) for all stations.
• The new limits will be automatically saved (nominal measured flow + 15 percent) for each
station.
2. Your system has been operational for some time. Occasionally, one or more stations
seemingly at random fail the flow upper limit. Upon physical inspection of the stations
everything appears fine. Upon further investigation it is determined that there are large
fluctuations in the static water pressure. It is desired to bump all stations from their existing
15 percent (above nominal) to 25 percent (above nominal).
Then:
• Set the flow percentage to 25 percent.
• All station limits will now be recalculated to provide another 25 percent over the initial
nominal readings.
This SETUP function will be skipped if you have not enabled the flow features.
EXAMPLE
: Assume the initial measured flow (nominal value) was 40 GPM for a station. Because
the flow percentage was originally 15% then the station upper limit as retained in the controller is
46 GPM (115 x 40). Now, setting the new flow percentage of 25% yields a new station limit of 50
GPM (125 x 40).

6.13.7 Limits
The Limits feature will allow you to set the station’s upper flow limits by either using the LEARN
mode or by setting them explicitly. The next 2 sections explain each of these methods.
This SETUP function will be skipped if you have not enabled the flow features.
