12.3.4 Flow Fine Tuning
After balancing is complete, if the flow at Point C requires
fine tuning, simply increase or decrease Parameter 20-21
Setpoint 1 until desired flow is achieved. Follow this pro-
cedure to adjust the setpoint.
1.Press the [Quick Menus] button.
2.Press the [OK] button to enter “My Personal
Menu.”
3.Scroll down to parameter 20-21 Setpoint 1
and press OK.
4.Enter the Pressure Head set point (ft WG) that will
achieve the desired flow. Then press OK.
a.Parameter 20-21 = Setpoint 1.
5.Press the [Auto on] button to start the pump.
6.Press the [Status] button to get back to the main
screen.
12.4 Additional Settings
Other settings that are set to enable the pump to operate
on a control curve are:
• Par. 22-80 (Flow Compensation), which should be
set to ‘Enabled’ [1]
• Par 22-81 (Square-linear Curve Approximation),
which should be set to ‘100%’.
Figure 12-7: Curve Approximation Settings
The effect of adjusting par. 22-81 is shown in Figure 12-7
above. A setting of 100% gives the ideal theoretical con-
trol curve between the design head and minimum head
while 0% provides a straight line linear approximation.
