working in heating mode at maximum
power, with cut off at 80°C and re-ignition
at 70°C (ATTENTION! Temperature may
reach excessive values when using unpro-
tected low temperature plants. Before
activating the chimney sweep function
make sure that the radiator valves or
eventual zone valves are open).
The test can also be carried out with the
boiler working in D.H.W. mode.
For this, after activating the chimney sweep
function, open one or more hot water fau-
cets. Under these conditions, the boiler

will function at maximum power with the
D.H.W. circuit kept at between 60°C and
50°C. During the test, the hot water faucets
must remain open.

4.5.2 Operation floor drying
(fig. 22)
2
The operation floor drying keeps the floor
at a pre-established temperature profile
and it is activated only for those systems 4
combined with the mixed zone card
ZONA MIX code 8092275/76.
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 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!
