During the air venting cycle, any heat requests are inhibited. To avoid this function, keep the button
seconds immediately after activation.
This function is performed under the following conditions:
• when the boiler is electrically powered.
• on resetting from error F37, F41, A03.
• when parameter P11 is set to 1.

1.2.3 Heating temperature adjustment

Use the buttons (ref. 3 and 4 of fig. 1 on page 6) to adjust the heating temperature.
The setting range is 30 - 80 °C and the default value is 60 °C.
To disable the heating function (summer mode), change the set point, bringing it below the minimum until the
symbol appears.
