6.12.1 External temperature sensor
The boiler is prearranged for connection to an external air tem-
perature 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.
33).
When fitting the sensor on the outside of the building, follow
the instructions provided on the packaging of the product itself.
