• The system was designed for a certain duty point (full load point, cal-
culated maximum heating capacity requirement). During commis-
sioning, the pump output (delivery head) is to be set according to the
duty point of the system.
• Works settings do not comply with the output required for the sys-
tem. It is determined with the help of the pump curve diagram for the
selected pump type (from catalogue/data sheet).
CAUTION! Caution – material damage!
If the volume flow is too low, it can cause damage to the mechani-
cal seal.
• Ensure that the minimum volume is not less than 10% of the max-
imum volume flow.

NOTE
Alternatively, the manual control mode (Fig. 39) or the PID operating
mode can also be set.
Manual control mode:
The "manual control mode" deactivates the control in the module.
The speed of the pump is kept to a constant value and set internally
using the rotary knob.
The speed range depends on the motor power.
PID control
By selecting a good combination of individual control portions, the
operator can ensure fast reacting, constant control without lasting
setpoint deviations.
