Setting the supply times for fuel supply (with vacuum system)

You can individually set specific times during which
you do not want fuel to be supplied.

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. Select the addresses
that have to be changed (see chapter "Code 1").

Setting 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.
