From the Webserver, choose Settings -> Pump, set control
mode to Parallel with the following parameter values:
A id: 1 to 8, the lower number is the lead pump
e.g. enter 1 for lead pump, 2 for lag pump
B Dead Band: set to 0.25
C Total Design Flow: enter the parallel flow rate
D Sensorless Map Adjust Factor: set to 0.1
e Minimum On Time (seconds): set to 15
Click update to save all changes. Connect the Webserver to
the second pump and then repeat above steps A to e.
