If, when turning the knob
B
on the main menu, the display visualises the boiler flow temperature instead of the ambient
temperature, parameter
742
has not been set correctly.
After every system configuration (e.g.: solar combination, connection an external storage boiler, etc.) perform the following
procedure to update the boiler board to the new configuration:

ZONE SYSTEM WITH INSTALLATION OF THE REMOTE CONTROL
The electrical connection and the adjustments required to manage a system divided into zones with use of the Remote Control
differs according on the accessories connected to the boiler. To install and configure, see the instructions of the
Expansion
Module
supplied as an accessory.
ADJUSTING THE TEMPERATURE OF THE HIGH TEMPERATURE HEATING SYSTEM
To avoid frequent starting and stopping, raise the minimum temperature setpoint of the boiler in the heating mode by setting
parameters
740
, to not less than 25°C, using the procedure described in point
B
.
TEMPERATURE ADJUSTMENT ON
LOW TEMPERATURE HEATING SYSTEM
For a low temperature system (such as underfloor heating), reduce the maximum CH temperature setpoint on the boiler by setting
parameter
741
(point B
)
to a value not greater than 55°C.
8.2 OUTDOOR SENSOR
The External Probe can be connected to the boiler as
illustrated in the figure to the side. The following procedure is
used to set a parameter, called
room influence
which is used
to determine the importance of the ambient temperature with
respect to the external temperature and vice-versa (the factory
setting is 50%-50%).
E.g.
: if the ambient influence is set to 60%, the influence of
the External Probe will consequently be 40% (the greater the
set value of ambient influence, the lesser the influence of the
External Probe will be in proportion, and vice-versa).
The following procedure is used to set ambient influence:
