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 effi ciency, 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

eff ective 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.
