IT IS FORBIDDEN
To use water pipes for earthing the appliance.
6.13.1 External temperature sensor
The boiler is prearranged for connection to an external air
temperature sensor and can operate with a sliding temper-
ature.
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 dia-
gram (Fig. 35).
When fitting the sensor on the outside of the building, follow
the instructions provided on the packaging of the product it-
self.

CAUTION
If there is an external sensor, turn the heating knob
t
until the required curve K has been selected with-
in the range
K=0.0 - K=9.0 in order to select the opti-
mal climatic curve for the system and therefore the
delivery temperature based on the external temper-
ature.

CAUTION
The adjustment of the Maximum Heating Tempera-
ture is managed by
"PAR 14" (see paragraph "List of
parameters").
6.13.2 Chrono-thermostat or Air Thermostat
The electrical connection of the chrono-thermostat or air
thermostat has already been described. When fitting the com-
ponent in the room where the readings are to be taken, follow
the instructions provided on the packaging of the product it-
self.
