3 6 Outdoor sensor installation
The outdoor sensor (optional) must be positioned correctly
in order to ensure the climate control's proper functionality.
The sensor must be installed outside the building to be
heated, at approx. 2/3 the height of the NORTH or NORTH
WEST façade and far from flues, doors, windows and sun-
ny areas.
Fastening the outdoor sensor to the wall
- Unscrew the sensor protection box cover, turning it
anticlockwise to access the terminal board and fas-
tening holes
- Trace the fastening points using the box as a tem-
plate
- Remove the box and drill the holes for the 5x25 ex-
pansion plugs
- Fasten the box to the wall, using the two supplied
dowels
- unscrew the nut on the fair lead, and insert a bipolar
cable (with a cross section of 0.5 to 1mm
2
, not sup-
plied) to connect the probe to terminals 7 and 8 (see
the scheme in the chapter "Multi-row wiring diagram")
- connect the two cable wires to the terminal board
without identifying the polarities
- fully tighten the cable gland nut and close the protec-
tion box cover.
b
The sensor must be positioned on a smooth wall sec-
tion. If there are exposed bricks or irregular walls, an
area with a smooth contact must be prepared.
Fig. 12
b
The maximum length of the connection between the
outdoor sensor and the control panel is 50 m. In the
case of connections with a cable length that exceeds
50 m, check compliance of the value read on the card
with a real measurement and adjust parameter 39 to
make any necessary correction.
b
The connection cable between the outdoor sen-
sor and the control panel must not have couplings.
If these are necessary, they must be watertight and
suitably protected.
b
Any channelisation of the connection cable must be
separated by live cables (230Vac).
