Adjusting Heating Curves - Viessmann Vitotronic 200 KW2 Installation And Service Instructions Manual

Adjusting heating curves

The heating curves illustrate the
relationship between the outside
temperature and the boiler water or
the flow temperature. To put it
simply:
The lower the outside temperature,
the higher the boiler water or flow
temperature. Room temperature
depends on boiler water or flow
temperature.
