Vitodens 200-W
Variable speed heating circuit pump in the Vitodens 200-W
The integral circulation pump is a highly efficient pump with substan-
tially lower power consumption than conventional pumps.
The pump speed and consequently the pump rate are regulated sub-
1
ject to the outside temperature and the switching times for heating or
reduced mode. The control unit transmits the current default settings
via an internal data BUS to the circulation pump.
Individually match the minimum and maximum speeds plus the speed
for reduced mode to the existing heating system using the control unit
codes.
In the delivered condition, the minimum pump rate (coding address
"E7") and the maximum pump rate (coding address "E6") are set to
the following values:
