3.3 Antifreeze protection

The antifreeze system, and any addition-
al protective devices, safeguard the boiler
against possible damage due to freezing.
This system does not guarantee protection
for the entire hydraulic system.
Where the outdoor temperature could fall
below 0°C, it is recommended to leave the
entire system on, setting the room thermo-
stat to a low temperature.
The antifreeze function is active even if the
boiler is in OFF (Figure 3.6).
Figure 3.6
If the boiler is turned off, have a qualified
technician empty the boiler (heating and
DHW circuit) and empty the heating system
and the DHW system.

3.4 Periodic maintenance

For efficient and regular boiler operation, it
is recommended that the boiler be serviced
and cleaned at least once a year by a tech-
nician from an authorised service centre.

During this check, the most important boil-
er components are inspected and cleaned.
This check may be performed within the
scope of a maintenance contract.

3.5 External cleaning

Before performing any cleaning
operation, disconnect the boiler
from the electric mains supply.
To clean, use a cloth soaked in soap and
water.
Do not use: Solvents, flammable substanc-
es or abrasive substances.

3.6 Operating anomalies

If the boiler is not working and an error code
flashes on the display and the
is shown, it is a volatile lockout. The boiler
is reactivated automatically once the fault
has been resolved (see "General LCD char-
acteristics" on page 8); the boiler is in
lockout mode (Figure 3.7).
Figure 3.7
Each fault is classified accord-
ing to the level of priority. If
more than one faults are detect-
ed at the same time, the most
urgent error code is shown.
Frequent safety lockouts should
be reported to an authorised
service centre.
