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 conrm B 742 (Flow temp setpoint room stat) B to conrm.
•
B (anti-clockwise) "---" then B to conrm.
If, when turning the knob B on the main menu, the display visualises the boiler ow temperature instead of the ambient
temperature, parameter 742 has not been set correctly.
After every system conguration (e.g.: solar combination, connection an external storage boiler, etc.) perform the following
procedure to update the boiler board to the new conguration:
• Access menu 2 as indicated at the beginning of this section.
•
B Conguration B B programme row 6200 then B.
•
B Yes then B to conrm.
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 congure, 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 45°C, using the procedure described in point B.
TEMPERATURE ADJUSTMENT ON LOW TEMPERATURE HEATING SYSTEM
For a low temperature system (such as underoor heating), reduce the maximum CH temperature setpoint on the boiler by setting
parameter 741 (point B) to a value not greater than 45°C.
11.2.2 CONNECTION TO A LOW TEMPERATURE DIRECT SYSTEM
The boiler can manage a low temperature zone without mixing valve.
For a low temperature system (such as underoor heating), reduce the
maximum CH temperature setpoint on the boiler by setting parameter
741 (point B) to a value not greater than 45°C.

2 External probe
3 Underoor heating system safety thermostat
4 Remote control
5 Low temperature underoor heating system
For this system conguration, it will be necessary to have a Remote
Control (available as optional accessory) set as ambient unit 1. Whit
this conguration, it is possible to manage heating zone 1 and the
DHW functions.
• Access menu 2 as described in section 11.1.2.
•
B Conguration
• B programme row 5977 (Function input H5) then
to conrm
•
B Heat generation lock
• B programme row 5978 (Contact type H5) then B
to conrm
•
B NC B (Now the safety thermostat is enabled)
• To set the possibility of DHW operation in case of triggering of the
safety thermostat:
•
C to return to the previous menu then B Boiler settings B
•
B programme row 2301 (Boiler pump on heat gen lock) then B to conrm
•
B On B
•
B programme row 2305 (Impact heat generation lock) then B to conrm
•
B Heating mode only B
This type of system requires the installation of a safety overheating thermostat (triggering temperature 50°) on the delivery
manifold on the oor system. The electric connection must be to contacts 1-2 of the M1 terminal box.
