50°C. During the test, the hot water fau-

4.5.2 Cleaning the filter "Aqua Guard
Filter System" (fig. 22)
To clean the filter, close the delivery/return
on/off taps, turn off the power to the con-
trol panel, remove the casing and empty the
boiler using the drain provided.
Place a container for collection underneath
the filter, unscrew the cap and proceed to
clean the filter, removing impurities and
limestone deposits.
Check the seal o-ring before reassembling
the cap with the filter.

4.5.3 Operation floor drying
(fig. 22/a)
The operation floor drying keeps the floor
at a pre-established temperature profile
and it is activated only for those systems
combined with the mixed zone card ZONA
MIX code 8092234.
The temperature profiles can be selected
by means of the installer parameter PAR
43:
0 = Not activated function
1 = Curve setting A
2 = Curve setting B
3 = Curve setting A + B
The turning off of the function happens
clicking on the button OFF (return of PAR
43 to the value 0) or automatically at the
end of the function.
The set of the mixed zone follows the deve-
lopment of the selected curve and reaches
a maximum of 55°C.
During the function all the other heating
demands are ignored (heating, sanitary,
antifreeze and chimney sweep).
During the functioning the display shows
the remaining days for the completion of
the function (example mains digits -15 = 15
days lack to the end of the function). The
diagram fig. 22/a reports the development
of the curve.
ATTENTION:
- Observe the relevant standards and
regulations of the floor manufacturer!
- Proper functioning is ensured only
when the plant is correctly installed
(hydraulic system, electrical installa-
tion, settings)! If not observed, the
floor might get damaged!

FUNCTIONING ANOMALIES

When there is a functioning anomaly, an
alarm appears on the display and the blue
luminous bar becomes red.
Descriptions of the anomalies with relative
alarms and solutions are given below:
– LOW WATER PRESSURE ANOMALY
ALARM 02 (fig. 23/1)
If the pressure detected by the transdu-
cer is lower than 0.5 bar, the boiler
stops and the display shows the alarm
"ALL 02".
Proceed with the pressure restoration
until the pressure indicated by transdu-
