Troubleshooting; S.a.r.a. Booster Function - Beretta EXCLUSIVE GREEN 25 CSI Installation And User Manual

S.A.R.A. BOOSTER function

If the winter mode is selected, the S.A.R.A. Booster
function is activated for the heating circuit and reaches
the required ambient temperature more quickly.
GREEN C.S.I. only:
DOMESTIC HOT WATER PRE-HEATING function
If the winter mode is selected, the domestic hot water
Preheating function is enabled. This function sets out to
keep the domestic hot water contained in the boiler hot,
thereby considerably reducing delivery waiting times.
The function should be selected to reduce power
consumption in areas where the mains water is not
particularly cold.
In this case, the Booster and Preheating (GREEN C.S.I.
only) functions are not activated.
