function is activated, it is performed every day at 3:00 a.m. if
set to start every day, or on Wednesdays at 3:00 a.m. if set to
start every week.
The maximum duration of the anti-legionella cycle is 4
hours; if this function is interrupted because the time has
been exceeded, the error message “ANTI-LEGIONELLA
FUNCTION NOT COMPLETED” will appear on the display.
The system will attempt to execute the function again the
following day.

The function is not performed when the boiler is OFF.

In the INFO menu, the NEXT ANTILEGIO parameter
indicates the number of days left until the next anti-
legionella cycle.
This function can be interrupted in advance in two different
ways:
-
set the boiler to OFF
or
-
select STATE
DHW
ANTILEGIO CUT OFF.
If the function is interrupted, it will be repeated at the same
time the next day, even if weekly programming is active.

ANTILEGIO FLOW: allows you to set the boiler delivery
temperature to the storage tank during the execution of the
anti-legionella function (default value 80°C)
ANTILEGIO TIME: allows you to set the function execution
time (default setting 03:00 AM)
ANTILEGIO TEMP: allows you to set the storage tank
retention temperature during the execution of the anti-
legionella function (70°C).

6.2.4 EMBEDDED CLOCK HEATING SCHEDULE
When the embedded clock is enabled (POR=1 - see above), a
default heating schedule is used to manage the ON/OFF timings
for each day of the week (operating mode = AUTO). if necessary,
the default heating schedule can be changed according to the
User’s needs. Refer to “2.10 TIME SCHEDULE” (User section)
for detailed instruction/guidance on how to access and change the
default heating schedule.

6.2.5 SETTING THE THERMOREGULATION
Thermoregulation (weather compensation) controlled by the
appliance, can only be enabled if an external sensor has
been installed and connected to the M4 terminal strip.
When the presence of an external sensor is detected,
the appliance immediately enables the thermoregulation
function and calculates a required outlet (flow) temperature
that is based on the external temperature and the chosen
climatic curve. The temperature measured by the outdoor
temperature sensor is displayed on the initial page in the top
right, alternating with the display of the time.
When thermoregulation is enabled (outdoor temperature
sensor present), the algorithm for automatically calculating
the outlet setpoint depends on the type of heat request.
In any case, the thermoregulation algorithm will not directly
use the outdoor temperature, but rather a calculated outdoor
temperature that takes into account the building’s insulation:
in buildings that are well insulated, the outdoor temperature
variations will have less impact than those that are poorly
insulated by comparison. Enabling THERMOREGULATION
occurs in the following way:

Using the REC10 it is possible to set the value of the following
parameters:
BUILDING TYPE:
it is indicative of the frequency with
which the value of the calculated outdoor temperature for
thermoregulation is updated, a low value for this setting will
be used for buildings that have little insulation.
Setting range: [5min - 20min]
Factory setting: [5min]
REACTIVITY EXT SENSOR:
it is an indication of the
speed with which variations of the measured outdoor
temperature affect the calculated outdoor temperature value
for thermoregulation, low values indicate high speeds.
Setting range: [0 - 255]
Factory setting: [20]
To change the value of the previous parameters, proceed as
described below:
- select TECHNICAL

BUILDING TYPE rather than REACTIVITY EXT
SENSOR
-
set the desired value.
Note:
The value of the calculated outdoor temperature used
by the thermoregulation algorithm is displayed in the INFO
menu under T EXT FOR THERMOREG.
