Connecting the outside temperature sensor
Insert and secure the connecting cable through the cable
entry. The outside sensor can be connected to the terminal
strip of the condensing boiler at connection AF, or to the
terminal strip of the control accessories.
When installing the appliance in places
where there is a risk of high electromagnetic
interference, it is advisable to t shielded
sensor and eBUS cables. The cable shield
should be connected at one end to the PE
potential in the control unit.

Connecting the cylinder sensor
Insert and secure the connecting cable through the cable en-
try. Connect the connection cable for cylinder sensor SF to the
SF terminals as shown in the wiring diagram.
When installing the appliance in places where

Connecting digital Wolf control accessories
(e.g. BM-2, MM, KM, SM1, SM2, ISM7e)
Only connect control units from the Wolf accessory range.
Each accessory is supplied with its own connection diagram.
Use a two-core cable (cross-section > 0.5 mm²) as the
connecting cable between the control unit accessory and the
condensing boiler.
When installing the appliance in places
where there is a risk of high electromagnetic
interference, it is advisable to t shielded
sensor and eBUS cables. The cable shield
should be connected at one end to the PE
potential in the control unit.
