Matching the control unit to the heating system
The control unit must be matched to the equipment level of the system. Various sys-
tem components are recognised automatically by the control unit and the relevant
codes are adjusted automatically.
■ For the selection of an appropriate scheme, see the following diagrams.
■ For coding steps, see page 41.
