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 thus the pump rate are set via codes on
the control unit. The control unit transmits the current default settings
to the circulation pump via an internal data BUS.
In the delivered condition, the minimum pump rate (coding address
"05" in the solar group) is set to 30 %. The maximum pump rate (coding
address "06" in the solar group) is set to 100 %.
