Matching the control unit to the heating system
The control unit must be matched to the
equipment level of the system. Various
system components are recognised

relevant codes are adjusted automati-
cally.
■ For the selection of an appropriate
scheme, see the following diagrams.
■ For coding steps, see page 66.
