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. 5).
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.
5). 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. 6).
Adjusting domestic hot water temperature
To adjust domestic hot water temperature, turn switch B (Fig. 7) clockwise to
increase and anticlockwise to decrease. The bar segments light up (every 3°C)
as the temperature is increased.
The selected temperature value appears on the display.
When choosing the temperature, both for heating and domestic hot water, the
display shows the value being selected. About 4 seconds after the selection
has been made, the modification is memorised and the display returns to the
delivery temperature read by the probe.
Working the boiler
Adjust the ambient thermostat to the required temperature (approx. 20°C). If
there is a demand for heating water, the boiler starts and the
