8.1 Outside sensor
The outside sensor is supplied seperately.
Mounting Location
The outside sensor should be mounted on the most exposed and coldest side of the
building (north or north-east) at a height of min. 2 m above ground.
When mounting the sensor mind external heat sources (heated chimneys, warm hot air
from air shafts, installation on black surfaces, thermal bridges in the wall, etc.) which
could falsify the measuring value. The cable outlet must always be directed downwards
in order to avoid the penetration of moisture. The outside sensor may not be mounted
close to transmitting or receiving equipment (on garage walls close to receivers for radio-
controlled garage door openers, amateur radio antennas, radio controlled alert systems
or close to large scale radio transmission equipment).
Electrical connection
For the electrical installation preferably use a 2-strand cable with a minimum cross-
section of 0,75mm² . The connection is made at the 2 screw terminals inside the sensor
case and may be interchanged. Connect the outside sensor to terminal 18 and 19 on
the terminal block in the boiler (see figure 7 and 8).
Mounting instructions
1. Route the sensor cable to the mounting location
2. Loosen lid screws from sensor case and remove top
3. Mount sensor base with enclosed central fastening screw. Use sealing ring! The
cable outlet must be directed downwards!
4. Insert the sensor cable so that the cable jacket is fully enclosed by the sealing lip.
5. Establish the electrical connection. The terminals may be interchanged.
6. Place the lid and screw it firmly onto the base. Ensure correct fit of sealing ring.
