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 set-
tings 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 %.
