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 code
8092233. The temperature profiles can
be selected by means of the installer para-
meter 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/a)
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". Bring the pressure back to
normal by means of the load faucet (turn
anticlockwise to open) until the pressure
indicated by the transducer is between 1
and 1.5 bars. ON COMPLETION OF THE
OPERATION, MAKE SURE THE LOAD
FAUCET IS CLOSED.
If the load procedure has to be repeated
several times, it is advisable to check
that the seal of the heating circuit is
intact (check that there are no leaks).
