ALL MODIFIED PARAMETERS SHOULD BE NOTED
DOWN IN THE TABLE AT THE END OF THIS MANUAL
(page 31).
The following procedure is used to access the four boiler pro-
gramming menus:
• from the main menu C.
• A and C (hold down for approx. 6 seconds)
B menu 1-2-3-4 (see gure to side and key).
• C to go back one menu at a time to the main menu.
When the Control Panel is wall-mounted enable the Room Temperature Sensor and ow temperature modulation as follows:
A) ROOM SENSOR
• Access menu 2.
• B Operator unit B to conrm.
• B programme row 40 (Used as) B.
• B (anti-clockwise) Room unit 1 B to conrm (the room sensor is now active).
• C to return to the previous menu then B Conguration B.
• B programme row 5977 (Function input H5) then B to conrm.
• B None B to conrm.
B) FLOW TEMPERATURE MODULATION
To set ow temperature modulation, disable parameter 742 (HC1). Proceed as follows:
• Access menu 2.
• B Temps / mode CH1 B to conrm B 742 (Flow temp setpoint room stat) B to conrm.
• B (anti-clockwise) “---” then B to conrm.
If, when turning the knob B on the main menu, the display shows the boiler ow temperature instead of the ambient tempe-
rature, parameter 742 has not been set correctly.
After every system conguration (e.g.: solar combination, connection an external storage tank, etc.) perform the following proce-
dure to update the boiler board to the new conguration:
• Access menu 2 as indicated at the beginning of this section.
• B Conguration B B programme row 6200 then B.
• B Yes then B to conrm.
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 congure, see the instructions of the Expansion Mo-
dule 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 pa-
rameters 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 underoor heating), reduce the maximum CH temperature setpoint on the boiler by setting
parameter 741 (point B) to a value not greater than 55°C.
11.2.2 OUTDOOR SENSOR
The outdoor sensor must be installed on an external wall of the
building that is to be heated (see gure SECTION F), conside-
ring the following instructions:
• work on a wall facing north/north-east (avoid direct sunshi-
ne;
• do not install on walls subject to the formation of damp or
moss (identify the presence of thermal bridges;
• do not install near fans, steam outlets or chimneys (it is im-
portant to avoid the external temperature controlled by the
probe being in uenced by external agents;
• ensure that the thickness of the wall used is suitable for
obtaining good heat insulation (do not x it to metal walls).
