Note
The appliance is delivered fitted with a flexible power cable (2 m
long). Lay the required power cables on site and route them into the
boiler through the underside.
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-
ject to the outside temperature and the switching times for heating
mode or reduced mode. The control unit transmits the current speed
specifications to the circulation pump via a PWM signal.
The min. and max. speeds and the speed for reduced mode can be
matched to the existing heating system via parameters at the control
unit.
Setting (%) in the heating circuit 1 group:
■ Min. speed: Parameter 1102.0
■ Max. speed: Parameter 1102.1
■ In the delivered condition, the minimum pump rate and the maxi-
mum pump rate are set to the following values:

■ In conjunction with a low loss header, heating water buffer cylinder
and heating circuits with mixer, the internal circulation pump runs
at a constant speed.
