Displaying the menu structure
If you exit the commissioning sequence by pressing
"
", the structure of the commissioning menu is dis-
å
played. From here, you can change to the standard
menu or the main menu.
Matching the control unit to the heating system
The control unit must be matched to the system equip-
ment level. Various system components are recog-
nised automatically by the control unit and the relevant
codes are set automatically.
Check all addresses in Code 1 and adjust if required
(see chapter "Code 1").
Adjusting the heating curves
The heating curves represent the relationship between
the outside temperature and the flow temperature.
To put it simply, the lower the outside temperature, the
higher the flow temperature.
The flow temperature in turn affects the room tempera-
ture.

The heating curve is offset along the set room temper-
ature axis. With the heating circuit pump logic function
enabled, the curve modifies the start and stop charac-
teristics of the heating circuit pump.
