SUMMER FUNCTIONING
Turn the selector [2] bringing it in the SUMMER
position
To regulate the temperature of the cold water produced by the boiler, pull and then turn the
knob
[4] for the DHW temperature regulation. The rotation usually requires a certain strenght:
— When the knob is placed inside the SUPERCOMFORT zone (on the right) the hot water outlet
is managed by the boiler in order to ensure the maximum stability of the flow temperature. The
positions on the right offer slightly lower but more stable temperatures and big flows which meet
the needs of several showers or basins of great sizes.
— Turning the knob in anticlockwise sense towards SUPERBOILER (on the left) you can obtain
progressively the maximum available temperature. This regulation is indicated when you need
very hot water.
In case of not ignition of the boiler (and consequently of cold water supply) check that the red lamp
[7] is not on: if it’s on, turn the selector [2] in the central Off/Unlock
Position, wait until the red
lamp [7] turns off, and then bring it again in the SUMMER position. See “Working and warning
indicators” for more information and useful advices to solve common problems.
REMARK: at the interval of 7 days the boiler automatically provides for the heating of the water in
the boiler to more than 60°C, so as to avoid eventual bacters which form in quiet water.
WINTER FUNCTIONING
Turn the selector [2] bringing it in the WINTER
Position.
Regulate the Boiler Thermostat
[3] at the desired temperature.
If a Room thermostat or a Cronothermostat is installed, the regulation of this last keeps the room
temperature as that arranged (refer to the respective using instructions). In this case it is useful to
regulate the boiler thermostat
according to the outdoor seasonal climate, so as to allow the
gaining of the desired temperature, but without excessive overheatings (consider that the radiators
emit heat also after the turning off of the boiler).
The hot water regulation is the same in both winter and summer mode: see previous “SUMMER
FUNCTIONING” for details.
In case of not ignition of the boiler, check that the red lamp [7] is not on: if it’s on, turn the selector [2]
in the central Off/Unlock
Position, wait until the red lamp [7] turns off, and then bring it again in
the WINTER Position. See “Working and warning indicators” for more information and useful
advices to solve common problems.
Important:
The temperature in the boiler is shown by the thermometer [5] and the pressure is shown by the
Gauge [6].
Remark: If pressure falls down to 0.5 bar, boiler will stop (the red lamp turns on). To reset the
system, proceed with system filling.
