B) FLOW TEMPERATURE MODULATION
To set flow temperature modulation, disable parameter 742 (HC1). Proceed as follows:
• Access menu 2.
• B Temps / mode CH1
• B (anti-clockwise)
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:
• Access menu 2 as indicated at the beginning of this section.
• B Configuration
• B Yes then B to confirm.
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 underfloor heating), reduce the maximum CH temperature setpoint on the boiler by setting
parameter 741 (point B) to a value not greater than 45°C.

Relay Room thermostat
The boiler can manage a zone heating system. The Control Panel (wall-mounted) can be used to control one zone while normal
ambient thermostats can be used to control the other zones.

SYSTEM CONNECTIONS

• Connect the zone 1 valve/pump to terminals 6-7 of terminal block M3, as described in section 14.
• Connect the Ambient Thermostat contact of the other zones to terminals 1-2 of terminal block M1.
CONFIGURING PARAMETERS
Set the Control Panel as Room unit 1. In this configuration, the Control Panel manages heating zone 1 and the DHW functions.
• Access menu 2 as described in section 14.2.1.
B Operator unit
•
• B (anticlockwise) Temps / mode CH1
• C to return to the previous menu then
• B programme row 5715 (Temps / mode CH2)
B programme row 5977 (Function input H5) then
•
• B Room thermostat CH2
• To set the open time of of the heating circuit 1 electrovalve, proceed as follows:
• C to return to the previous menu and then
• B to the maximum electrovalve open time (expressed in seconds) and then
A MIXED ZONE SYSTEM CAN BE MANAGED VIA AN EXTERNAL MODULE SUPPLIED AS AN ACCESSORY. TERMINALS 6-7
OF TERMINAL BLOCK M3 ARE AVAILABLE IF NOT USED FOR OTHER CONFIGURATIONS.
