Fastening the outside probe to the wall
- Unscrew the cover on the probe protection box, turning
it anticlockwise to access the terminal block and the
fastening holes
- Trace the fastening points using the protection box as
the template
- Remove the box and drill the holes for the 5x25 expan-
sion plugs
- Fasten the box to the wall using the two plugs supplied
- Unscrew the nut on the cable gland, pass a two-wire
cable through (cross-section from 0.5 to 1mm
2
, not
supplied) to connect the probe to terminals 7 and 8
(see the diagram on page 34)
- Connect the two wires on the cable to the terminal
block, without needing to identify the polarity
- Tighten the nut on the cable gland and close the cover
on the protection box.
b
The probe should be placed on a smooth section of
the wall; in the event of exposed brick walls or une-
ven walls, a smooth contact area should be used.
b
The maximum length of the connection between
the outside probe and the control panel is 50 m.

b
The connection cable between the probe and con-
trol panel must not have junctions; if required, these
must be sealed and adequately protected.
b
Any conduits used for the connection cable must
be separate from the power cables (230Vac).
The correct positioning of the outside probe is fundamental for the correct operation of the climate control function.
The probe must be installed outside of the building being heated, at a height of around 2/3 of the wall facing NORTH or
NORTH-WEST, and away from flues, doors, windows and areas exposed to direct sunlight.
