7.12 - Timers of the various functions
To safeguard the lifespan of the appliance, improve the comfort
generated and increase energy saving, timings have been
introduced during operation. These timings are:
- Pump post-circulation: every time that the room thermostat
determines the end of the central heating service, the pump
continues to operate for 3 minutes;
- Central heating delay: every time that the domestic hot water
service finishes, before reactivation of the central heating
service there is a stand-by period of 2 minutes;
- Pumps anti-block and diverter valve: every 24 hours, the
central heating pump, the domestic hot water pump (if
present) and the diverter valve are forced;
- Anti-legionella; if the boiler is connected to a indirect water
heater for preparation of the DHW., every seven days the
latter is forced to a temperature of 60°C to disinfect against
the legionella bacteria. This function activates also due
hours after the boiler has been powered electrically.
- Ignition delay: In all operating modes, excluding domestic
hot water mode, wait 3 minutes to ignite the burner again
when it switches off.
7.13 - Pumps anti-blocking
and diverter valve
The pump switches on once every 24 hours for 15 seconds
during the summer period in order to prevent any deposits
that may block it. The diverter valve and the indirect water
heater pump (if present) are activated at the same time for
the same reason.
7.14 - Anti-freeze protection
ATTENTION !!! For the anti-freeze protection
to be effective, the appliance must be left with electric
power supply and gas supply present and the two
services (domestic hot water and central heating) in the
OFF
position.
ATTENTION !!! The anti-freeze protection
service offered by the boiler cannot guarantee the
anti-freeze protection of the central heating plant, the
domestic hot water plant or the building served or part
of the same.
The central heating pump starts automatically when the boiler
temperature reaches 10°C.
If the temperature drops further below 5°C, the burner also
ignites in a way to protect the boiler from the effects deriving
from freezing.
If the boiler is not used for a long period of time (over a year),
it is recommended to empty it following the procedures in
chapters 8.16 and 8.17.
7 - USE
7.15 - Automatic plant
filling (on request)
Normally the appliance is supplied with a manual cock for
filling the central heating plant. On request, the boiler can be
manufactured with the automatic plant fill.
7.16 - Energy Saving
To reduce the consumption of display energy, it will switch
off automatically after 5 minutes from the last operation
performed. This function can be deactivated or the time
modified via parameter
2100
present in the “Installer menu”.
If the parameter is set at
OFF
, the display will remain on
constantly.
