Control unit programming

Warning: close the control unit with the
screws before powering on.
The are two options:
Scenario no. 1: the boiler includes a BUS Bridge-
Net® connection; configurations are made from the
boiler or from an the system interface (option).
Scenario no. 2: the control unit is independent,
and the zones are configured from the system in-
terface 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 reco-
gnises the equipment and carries out automatic
initialisation

Configuring the control unit using the sys-
tem interface
1) Switch on the display by pressing the OK key. The
screen is activated.
2) Press and hold the
tem interface simultaneously for 5 seconds.
3) Using the "encoder" button, display code 234
then confirm with the OK key.
4) Turn the button clockwise to access the MENU
option then confirm with the OK key.
5) Look for menu 7 "Multizone Module" using the
"encoder" button then confirm with the OK key.
Select sub-menu 72 "Multizone" then confirm
with the OK key. Select parameter 720 then
confirm with the OK and select the parameter
that corresponds to the hydraulic configuration
according to the table below, then confirm with

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 bleed function activated, the module
performs an ON/OFF circulating pump, the
mixing valve. This causes the air in the circuit to
start circulating. You can activate a new cycle if
necessary.

Frost protection function

If the flow sensor records a temperature lower than
5°C, the frost protection function is activated. If the
frost protection function is activated, the module
starts the circulating pump. This allows frost
protection to be extended to zones 1 and 2.

Anti-jamming function

After every 24 hours of inactivity, an anti-jamming
cycle is performed on the circulating pump and the
mixing valve.
