Circulation pump for heating and solar 47

8. PWM speed control

8.1 Control

Circulation pumps with PWM connection can be speed-controlled
via an appropriate control. In the process, the external signal
(Pulse-Width-Modulation) is transmitted from the controller to the
pump. The connection is via a two-core control cable.
Two different modulation variants are available for selection:
PWM1 is suitable for the control of heating and geothermal systems.
PWM2 is frequently used in solar systems.
Note: The PWM1 signal is set for the start-up. The PWM2 signal must
be selected manually.
Highly efficient. Simple. Good!
