Comfort Function.
COMFORT function
The boiler allows the ‘comfort’ level for the output of domestic hot
water to be increased through the “COMFORT” function. This function
keeps the secondary exchanger (or external tank) warm during the
periods in which the boiler is inactive, thereby bringing the initial
thermal condition of the water drawn to a higher temperature.
This function may be enabled by pressing the COMFORT button 5.
When the function is enabled the text COMFORT appears on the
display.
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 e 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 e 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 o , 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.
Switching o the boiler
To switch o the boiler press the ON/OFF button, the display will
switch o .
The Anti-frost Function is allready active.
ATTENTION!!
