Matching The Control Unit To The Heating System - Viessmann VITODENS 200-W Service Instructions Manual

Further details regarding the individual steps

Matching the control unit to the heating system

Note
Subject to the equipment level, the control unit must be matched to the system.
Various system components are recognised automatically by the control unit
and the relevant codes are adjusted automatically.
In the following system designs, DHW heating is illustrated with a separate
DHW cylinder. The designs also apply to systems where DHW is heated by an
integral instantaneous water heater.
For the selection of an appropriate design, see the following diagrams.
For coding steps, see page 36.
