preparing the boiler for operation
Module programming
The are two options:
Scenario no. 1: the boiler includes a BUS BridgeNet® connection;
confi gurations are made from the boiler or from an the system inter-
face (option).
Scenario no. 2: the module is independent, and the zones are confi -
gured from the system interface supplied as an option.
Initialisation
Before starting the procedure, check that all the circuits have water
and that the purge was carried out correctly.
Once all equipment is connected, the system recognises the equip-
ment and carries out automatic initialisation.

Confi guring the module
using the system interface
1) Switch on the display by pressing the OK key. The screen is activa-
ted.
2) Press and hold the
and OK keys on the system interface
simultaneously for 5 seconds.
3) Using the "encoder" button, display code 234 then confi rm with
the OK key.
4) Turn the button clockwise to access the MENU option then con-
fi rm with the OK key.
5) Look for menu 7 "Multizone Module" using the "enco-
der" button then confi rm with the OK key. Select sub-menu
72 "Multizone" then confi rm with the OK key. Select parameter
720 then confi rm with the OK key and select MGm II parame-
ter 2 then confi rm with the OK key.
Confi guring the module from the boiler
1) Press the menu/ok key. When CODE is displayed, press menu/ok;

Air bleeding
The module's automatic air bleed function is only activated from the
boiler if there is a BUS BridgeNet® connection (scenario no. 1).
The air bleed function is activated by pressing and holding the esc
key on the boiler for 5 seconds or by activating parameter 7 0 1.
With the purge function active, the module performs a circulating
pump ON/OFF cycle. This causes the air in the circuit to start
circulating. You can activate a new cycle if necessary.
Frost protection function
If the fl ow sensor records a temperature lower than 5°C, the frost
protection function is activated. If the frost protection function is
active, the module starts the circulating pumps.
Anti-jamming function
After a downtime of 24 hours, a cycle is run to prevent the circulating
pumps from jamming.
