Beretta EXCLUSIVE MIX C.S.I. Manual Para La Instalación Y El Uso página 16

If the test is successful the boiler is ready to work about
4 seconds after the cycle ends.
The display will look like fig. 12.
If the test is unsuccessful, the boiler will not work and a "0"
will flash on the display.
In this case, contact the Technical Assistance Centre.
The boiler turns on in the status it was in before it
was switched off: if the boiler was in the winter mode
when it was switched off, it will turn on again in the
winter mode. If it was in the OFF mode, the display
will show two segments in the central area (fig. 13).
Press the button to enable operation.
- press the function selector until the indicator moves to
the required function
operation chosen.
MIX C.S.I.:
- AUTUMN : with the selector in this position, the
heating water and domestic hot water functions are
activated.
In this position the S.A.R.A. function is enabled in the
heating mode (see chapter "Functions").
The boiler actives the temperature stabiliser in order to
ensure the continuous production of domestic hot water,
even for small demands or when the inlet water is already
hot.
This prevents temperature oscillations due to the burner
switching off/on.
- WINTER : with the selector in this position, as well
as the traditional function of heating water and domestic
hot water, the preheating function is also activated which
keeps the water in the domestic hot water exchanger
hot in order to reduce waiting times. The S.A.R.A. Booster
and Domestic hot water preheating functions are enabled
in this position (see chapter "Functions").
- SPRING : with the selector in this position, just the
traditional domestic hot water function is activated.
- SUMMER : with the selector in this position, the boiler
provides just domestic hot water with a temperature
stabiliser for small deliveries. Ideal at the times of year
or in the areas where the mains water is already warm.
In these conditions, the temperature of the hot water
produced by a boiler with just traditional functions (see
SPRING and WINTER) may be instable.
MIX R.S.I.:
- AUTUMN : with the selector in this position the
S.A.R.A. function is enabled (see chapter "Functions").
- WINTER : with the selector in this position the S.A.R.A.
Booster function is enabled (see chapter "Functions").
Note: both in autumn and in winter, if external water
tank is connected, the boilre provides hot water (with a
temperature stabiliser) to the water tank, to let preparing
the domestic hot water (see parameters table).
- SPRING (only with water tank connected): with
the selector in this position the boiler provides water (with
a temperature stabiliser) to the water tank, to let preparing
the domestic hot water (see parameters table).
- SUMMER (only with water tank connected): with
the selector in this position, the boiler provides just water
(with a temperature stabiliser but smaller than spring
position) to the water tank, to let preparing the domestic
hot water (see parameters table).
