USER’S MANUAL Auto button - Temperature adjustment activation The AUTO function enables boiler operation to be adapted to environmental conditions and to the type of system it is installed on. Comfortable temperature is reached inside the room in the quickest way possible, without wasting money, energy or efficiency, while substantially reducing the amount of wear experienced by the components. Your installer will advise you on the devices connectable to the boiler and will program it according to the system. In normal boilers the water temperature inside the heating elements is usually set to a high value (70-80°C), thereby ensuring effective heating during the few really cold winter days. It then becomes excessive on less cold days (of which there are many) more typical of the autumn and winter seasons. This leads to excessive room heating after the thermostat has been switched off, resulting in energy waste and uncomfortable conditions inside the room. The AUTO function “takes control” of the boiler and selects the best operating regime based on environmental conditions, external devices connected to the boiler and the performance required. It constantly decides at which power level to operate based on the environmental conditions and the room temperature required. This function may be enabled by pressing the AUTO button 7. When the function is enabled the text AUTO appears on the display. 26/10/21 16:23 0° 40° 1,5 bar 70° AUTO C Heating active User’s Manual / 9
