Figure 9.2: The curve of the Manual
Mode
In this operating mode, the pump
sets its speed fixed on the selected
rpm. The speed is set by 50 rpm
intervals.
9.2 Constant Pressure Operating Mode
Figure 9.3: The curve of the Constant Pressure Mode
In this operating mode, the pump sets its speed to keep the selected head value
(H
set
) stable.
How to select the H
set
value is given below:
• The operating point (the head and flow) of the system is determined.
• If the head is a multiple of 0.5, the exact value of the system is selected as
H
set
.
• If the head is not a multiple of 0.5, the closest value is selected as H
set
.
In the following graph, the curves of the operating modes are drawn with 1
meter intervals. The head can be set by 0.5m intervals on the display.
According to the rule given above:
• A is set at 7.5m
• B is set at 7.5m
• C is set at 8m
• D is set at 8m
