CAUTION
It is compulsory:
– to use an omnipolar cut-off switch, disconnect switch,
in compliance with EN standards (contact opening of
at least 3 mm)
– if the power cable is to be replaced, that ONLY a spe-
cial cable is used with a factory produced re-wired
connector, ordered as a spare part and connected by
a professionally qualified person
– to connect the earth wire to an effective earthing sy-
stem (*)
– that before any intervention on the boiler, the mains
power is disconnected by setting the main system
switch to "OFF".
(*) The manufacturer is not responsible for any damage caused
by failure to earth the appliance or failure to observe the infor-
mation provided in the wiring diagrams.
d
IT IS FORBIDDEN
To use water pipes for earthing the appliance.
6.12.1 External temperature sensor
The boiler is prearranged for connection to an external air tempe-
rature sensor and can operate with a sliding temperature.
This means that the delivery temperature sent to the boiler can
vary on the basis of the external temperature depending on the
climatic curve selected from those shown in the diagram (Fig. 39).
When fitting the sensor on the outside of the building, follow the
instructions provided on the packaging of the product itself.

CAUTION
If there is an external sensor, turn the heating knob t
until the required curve K has been selected within the
range K=0.0 - K=9.0 in order to select the optimal clima-
tic curve for the system and therefore the delivery tem-
perature based on the external temperature.
