5 k NTC header sensor SAF; alternatively 0-10 V or floating
contact
Connecting the outside sensor
The outside sensor can be connected to the terminal strip
of the heat pump at connection AF, or to the terminal strip
of the control accessories.
No external voltage may be connected to input
Please
AF, as this will destroy the component.
note

(e.g. BM-2, MM, KM, SM1, SM2)
Only controllers from the WOLF range of accessories may
be connected. 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 accessory and the
BWL-1S (1 is + and 2 is -).
When installing the appliance in places where
Please
there is a risk of increased electromagnetic
note
interference, it is advisable to fit screened
sensor leads and eBUS cables. The cable
shield should be connected at one end to the
PE potential in the control unit.
