Variable speed solar circuit pump in the Vitodens 242-F
The integral solar circuit pump is a highly efficient circulation pump
with substantially lower power consumption than conventional
pumps.
The min. and max. speed and therefore the pump rate are set via
parameters on the control unit. The control unit transmits the current
speed specifications to the circulation pump via PWM signal.
