Adjusting heating water temperature with an external sensor
connected
When an external probe is connected, the value of the delivery temperature is
automatically chosen by the system which rapidly adjusts ambient temperature
to the changes in external temperature. Just the central segment of the bar is
illuminated (Fig. 7).
To increase or decrease the temperature with respect to the value automatically
calculated by the electronic board, turn the heating water selector clockwise to
increase and anticlockwise to decrease. The bar segments light up (at every
comfort level), correction tolerance lies between - 5 and + 5 comfort levels (Fig.
7). When choosing the level of comfort, the digit area of the display shows the
required level of comfort while the bar shows the matching segment (Fig. 8).

temperature read by the sensor.
