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 values measured by the probe to be higher
than those of a reference probe, immediately following installation. THERMOREGULATION is activated and optimised by setting the following parameters:

BUILDING TYPE
MAXIMUM HEATING SET-POINT
MINIMUM HEATING SET-POINT
THERMOREGULATION FUNCTION ACTIVATION
CLIMATIC COMPENSATION CURVE
TYPE OF HEAT REQUEST
Thermoregulation function activation PARAMETER 44.
The connection of the external temperature probe, plus the value of PA-
RAMETER 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 THERMOREGULATION function.
Without the connection of the external probe, it is not possible to en-
able the THERMOREGULATION.
In this case, PARAMETER 44 is ignored and its function is ineffec-
tive.
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 THERMOREGULA-
TION function are not visualised.
PARAMETER 03. Type of building
The adjustment system for processing the delivery temperature does not
use the external temperature directly, but takes into account the thermal
insulation of the building: in well-insulated buildings, external temperature
variations have less effect on the ambient temperature compared with poor-
ly insulated buildings. The level of thermal insulation of the building is set
via parameter 3, in compliance with the enclosed diagram.

Choice of the climatic compensation curve PARAMETER 45.
The compensation curve for heating calculates
the delivery temperature of the boiler based on particular parameters, opti-
mising the operation 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:

Maximum and minimum delivery temperature PARAMETERS 21 and 22 -
There are two parameters that allow you to limit
the delivery temperature produced automatically by the THERMOREGULA-
TION function based on the type of system (see table).
System type
Cast iron radiators
Radiating panels
Fan coils
Floor
PARAMETER 21 determines the maximum delivery temperature (MAXI-
MUM HEATING SET-POINT).
PARAMETER 22 determines the MINIMUM DELIVERY TEMP. (MINIMUM
HEATING SET-POINT).

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 between
curve 7.5 and curve 10. In this case select the closest curve being 10.
Note: if the memory function is ON, the boiler turns on at the delivery tem-
perature calculated according to the value detected by the external probe,
and increases the memorised delivery temperature by 5°C after 10 minutes.
The Memory repeats the cycle until the ambient temperature set on the
thermostat is reached or until the maximum permissible temperature is
reached. In this case the lower thermoregulation curve should be selected.
Select curve 7.5 following the previous example.
