3.6 Installing the external probe
The correct operation of the external probe, supplied as an accessory,
is fundamental for the good operation of the climatic control.
INSTALLING AND CONNECTING THE EXTERNAL PROBE
The probe must be installed on an external wall of the building to be
heated, observing the following indications:
- it must be mounted on the side of the building most often exposed
to winds (the NORTH or NORTHWEST facing wall), avoiding direct
solar irradiation;
- it must be mounted about 2/3 of the way up the wall;
- it must not be mounted near doors, windows, air outlet points, or
near smoke pipes or other heat sources.
The electrical wiring to the external probe is made with a bipolar cable
with a section from 0.5 to 1 mm
length of 30 metres. It is not necessary to respect the polarity of the
cable when connecting it to the external probe. Avoid making any
joints on this cable however; if joints are absolutely necessary, they
must be watertight and well protected.
Any ducting of the connection cable must be separated from live
cables (230V AC).
FIXING THE EXTERNAL PROBE TO THE WALL
The probe must be placed on a smooth part of the wall (Fig. 4); in the
case of exposed brickwork or an uneven wall, look for the smoothest
possible area. Loosen the plastic upper protective cover by turning
it anticlockwise.
After deciding on the best fixing area of the wall, drill the holes for the
5x25 wall plug.
Insert the plug in the hole. Remove the card from its seat.
Fix the box to the wall, using the screw supplied.
Attach the bracket, then tighten the screw.
Loosen the nut of the cable grommet, then insert the probe connection
cable and connect it to the electric clamp.
To make the electrical connection between the external probe and
the boiler, refer to the "Electrical wiring" chapter.
Remember to close the cable grommet well, to prevent any air
humidity getting in through the opening.
Put the card back in its seat.
Close the plastic upper protective cover by turning it clockwise.
Tighten the cable grommet very well.
3.7 Installation of the remote control panel
To correctly check the ambient temperature, the control panel should
be installed in a reference position in the home.
For a correct installation, keep in mind that the panel:
- it should be installed on a wall, preferably not a perimeter one, that
has no hot or cold pipes running through it
- it should be fixed about 1.5 m from the ground
- it should not be installed near doors or windows, cooking
equipment, radiators, fan coils or generally in conditions that might
alter the measured temperatures.

In order to fix the panel to the wall, proceed as follows:
- separate the control panel from the base
- use the base as a template for marking the fixing points on the wall
- drill holes in the wall (ø 6 mm holes)
- fix the base to the wall using the screws supplied
- insert 2 type AA batteries;
- attach the top part of the panel to the base
- connect the red wires of the USB cable of the WiFi Box to the OT
clamp of the boiler - see wiring diagram
