4.5 Setting the thermoregulation
Checking the external probe connection
After connecting the external probe to the boiler, you can use the
INFO function to check, viewing the value of the external T° and
checking the presence of the icon on the display, that the connection
has been recognised by the adjustment card. It is normal for the val-
ues measured by the probe to be higher than those of a reference
probe, immediately following installation.
THERMOREGULATION is activated and optimised by setting the fol-
lowing parameters:

Thermoregulation function activation PARAMETER 44.
The connection of the external temperature probe, plus the value of
PARAMETER 44 ON, allows the activation of the thermoregulation:
EXTERNAL PROBE CONNECTED and PARAMETER 44 = 1 (ON)
The THERMOREGULATION is enabled.
The INFO function allows you to see the value of the external probe,
and to visualise the symbols associated with the THERMOREGULA-
TION function.
Without the connection of the external probe, it is not possible
to enable the THERMOREGULATION.
In this case, PARAMETER 44 is ignored and its function is in-
effective.
EXTERNAL PROBE CONNECTED and PARAMETER 44 = 0 (OFF)
- in this case, the THERMOREGULATION is disabled, even though
the external probe is connected. The INFO function allows you to see
the value of the external probe however.
Symbols associated with the THERMOREGULATION function are
not visualised.

Maximum and minimum delivery temperature PARAMETERS 21
and 22 -
There are two parameters that allow to limit the delivery tempera-
ture produced automatically by the THERMOREGULATION function
based on the type of system (see table).
System type T° max T° min
Cast iron radiators 80 60
Radiating panels 50 30
Fan coils 50 30
Floor 40 20
PARAMETER 21 determines the maximum delivery temperature
(MAXIMUM HEATING SET-POINT).
PARAMETER 22 determines the MINIMUM DELIVERY TEMP. (MIN
-
IMUM HEATING SET-POINT).
Choice of the climatic compensation curve PARAMETER 45.
The compensation curve for heating calculates the delivery tempera-
ture of the boiler based on particular parameters, optimising the op-
eration based on the outside temperature
Therefore the choice of the curve depends on the minimum external
design temperature (and therefore on the geographical location - see
graph 1), and on the delivery design temperature (and therefore on
the type of system)
For the calculation a comfort temperature of 20° is assumed (the
value 20 is used exclusively for the choice of the curve and does not
limit the possibility to adjust the ambient temperature to higher levels)
and is calculated using the following formula:
design delivery temp. -20
20- min. design external T.
P. 45 = 10 x
If the calculation produces an intermediate value between two
curves, you are advised to choose the compensation curve nearest
the value obtained.
Example: if the value obtained from the calculation is 9, this is be-
tween curve 7.5 and curve 10. Choose the nearest curve, i.e. 10.
Note: if the memory function is ON, the boiler turns on at the delivery
temperature calculated according to the value detected by the exter-
nal probe, and increases the memorised delivery temperature by 5°C
after 10 minutes.
Memory repeats the cycle until the ambient temperature set on the
ambient thermostat is reached, or until the maximum permitted tem-
perature is reached. In this case the lower thermoregulation curve
should be selected. Select curve 7.5 following the previous example.
