The successive pressing of the key C or D allows you to set the value of the heating setpoint
within the preset range:
[40°C - 80.5°C] for high temperature systems
[20°C - 45 °C] for low temperature systems
with steps of 0.5°C.
The level bars beside the heating icon show the setpoint value set with respect to the operating

cement modifying the set value.
If no key is pressed for 5sec, the value set is taken as the new heating setpoint and the display
returns to the main page.
8.3 Adjusting the heating water temperature with an outdoor
temperature sensor connected
If an outdoor temperature sensor is installed and thermoregulation is enabled (parameter
P4.18=1), the delivery temperature is automatically selected by the system, which quickly adjusts
the ambient temperature according to the variations in the outdoor temperature.
If you want to change the temperature, raising it or lowering it with respect to that automatically
calculated by the electronic board, it is possible to change the HEATING setpoint selecting the
desired comfort level within the range (-5 - +5).
Note: if an outdoor temperature sensor is connected it is in any event possible to have the boiler
operate at a fixed point by setting the parameter P4.18 = 0 (menu P4).
8.4 Adjusting the domestic hot water temperature
