COMFORT function (E-COMBI EVO models)
The comfort mode has priority over any other heating request.
There are two settings for the comfort mode (they can be adjusted
in the parameters menu):
1. As soon as DHW is drawn, the secondary heat exchanger is kept
warm for 30 mins.
2. As soon as DHW is drawn, the secondary heat exchanger is kept
warm permanently.
This function may be enabled by pressing the COMFORT button.
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.
