3 6 Outdoor sensor installation

The correct positioning of the outdoor sensor is of funda-
mental importance for proper climate control operation.
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
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.

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).
