The mainline break threshold should be higher than the station(s) with the highest flow rate. For example, if the station with the highest flow is 60GPM, then 20% higher would be approximately 75 GPM. For Thresholds of 30 GPM and lower, the GPM value can be set in 1 GPM increments, and for GPM values higher than 35 GPM, the increment is 5 GPM.
1. View Learned Flow data in the Station Flow screen in the PREVIEW menu to determine which station has the highest flow rate.
2. Reset the Mainline Break Threshold to 20% higher than the highest possible station flow. Press the FLOW button.
3. Press the à button until the SELECT FLOW OPTION screen displays.
4. Press the + or – button to select Mainlines.
5. Press the à button, then press the + or – button to select the desired mainline.
6. Press the à button to underline the GPM value.
7. Press the + or – button to increase or decrease the default value of 50 GPM.
8. Set the Mainline Break Delay time long enough to allow mainline flow to stabilize before the controller checks for a mainline break. Press the à button to select the Delay Period. Press the + or – to change the values.
Note
Any Flow Monitoring feature can be turned off independently of other flow monitoring functions by pressing the ß or à button to the 0 value, which will display as “Off.”
