Checking the connection with the external probe
After connecting the external probe to the boiler, use the
INFO function to check that the probe has been
automatically recognised by the temperature control card.
Immediately after installation, the value read by the probe

PARAMETER 03. Type of building
In order to calculate delivery temperature, the tem-
perature control system does not directly use the
external temperature value but considers the heat
insulation of the building: in well-lagged buildings,
external temperature variations affect the ambient
temperature less than they do in badly-lagged
buildings. Use parameter 3 to set the heat
insulation level of the building according to the
following scheme:
New houses Case vecchie
Hollow bricks Solid bricks Stones
a 19 14 12 8
b 20 16 15 11
c 19 15 14 9
d 18 12 10 5

may very well be higher then that measured by a reference
probe.
Enable and optimise the THERMOREGULATION function
by setting the following parameters:
PARAMETERS 21 and 22. Maximum and minimum
delivery temperature
These two parameters limit the delivery temperature
automatically produced by the TEMPERATURE
CONTROL function. PARAMETER 21 deter mines
MAXIMUM DELIVERY TEMPERATURE (MAXIMUM
PARAMETER 45. Choosing the offset temperature
curve (graph 1)
The offset heating curve maintains a theoretical ambient
temperature of 20°C at external temperatures ranging
from +20°C to -20°C. The choice of the curve depends
on the rated minimum external temperature (on the
geographical area, therefore) and the rated delivery tem-
perature (on the type of system, therefore) and must be
carefully calculated by the fitter using the following for-
mula:
rated delivery T - 20
P. 45 = 10 x
20- rated min. external T
PARAMETER 44. Enable thermoregulation function
The connected external temperature probe combined with
PARAMETER 44 provides the following operating modes:
EXTERNAL PROBE CONNECTED and PARAMETER
44 = 0 (OFF) in this case the TEMPERATURE CONTROL
function is disabled even though the external probe is
connected. The temperature read by the external probe
can always be viewed by pressing the INFO button. The
TEMPERATURE CONTROL symbols are not displayed.
HEATING SET POINT) while PARAMETER 22
determines MINIMUM DELIVERY TEMPERATURE
(MINIMUM HEATING SET POINT).
EXTERNAL PROBE CONNECTED, PARAMETER 44 =
1 (ON) in this case the TEMPERATURE CONTROL
function is enabled. The temperature read by the external
probe and the TEMPERATURE CONTROL symbols can
be viewed by pressing the INFO button.
The TEMPERATURE CONTROL function cannot
be enabled unless the external probe has been fitted
and connected. In this case, PARAMETER 44 is
ignored and has no effect on boiler operation.
If, from your calculations, you obtain an intermediate value
between two curves, we suggest choosing the
compensation curve closest to the value obtained.
Example: if the value obtained from the calculations is
8, this is between curve 7.5 and curve 10. In this case,
choose the closest curve, which is 7.5.
