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.

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 fl ow 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.
