Speed regulation by PWM
PWM input signal (PWM IN)
While the percentage of the PWM signal (work factor) is low, in case the input signal changes
up and down at the switch point, the hysteresis can prevent the circulation pump from start-
ing and stopping. In the absence of the PWM signal percentage, the circulation pump will
stop for safety reasons. If the signal is lost due to faulty or any other reason, the circulation
pump will stop to prevent the solar system from overheating.

Signal connection (only for AMG SOLAR)
On the PWM signal cable, the black line is connected to the GND mark on the control
panel, the red line is connected to the Input (In) mark, and the yellow line is connected to
the Output (out) mark.
