INSTALLATION AND OPERATING MANUAL
The appliance is fitted for connection to an external probe, available on request, which independently adjusts delivery
temperature depending on the external temperature and the chosen curve.
To mount and electrically connect this accessory, see the figure below and the instructions supplied with the external
probe.
The external probe must be installed on a wall outside the building as follows:

r %POPUJOTUBMMOFBSGBOTTUFBNPVUMFUTPSDIJNOFZT
Attach to the wall using the two supplied expansion grips, following the technical instructions supplied with the acces-
sory.
Make electrical connections to the probe using two wires with a minimum cross-section of 0.5 mm2 and a maximum length
of 20 m (polarity is unimportant).
Fix one end of the Module-Probe connection cable to the probe terminal block, securing it with the relative sealed grommet,
and the other end to the screw connector (CN4: B9 - M) on the electronic board (to access the electrical components
see section 10.1).
Use a harmonised cable “HAR H05 VV-F” 2 x 0.75 mm2 with a maximum diameter of 8 mm.
15. INSTALLING ANC CONNECTING THE EXTERNAL PROBE (accessory available on request)
With the external probe, the
TCH potentiometer
on the electronic board limits maximum heating temperature.
Attention: with the external probe connected, switch 6 on the electronic board must be turned ON.
SWITCH 6 = ON
