1.17 SYSTEM FILLING

Once the hydronic module is connected, fill the system using the
filling cock (Fig. 21).
The hydronic module has one incorporated automatic vent valve
located on the circulator pump and another on the central heating
manifold.
Make sure that the hoods are loosened.
The filling cock must be closed when the hydronic module pressu-
re gauge indicates approximately 1.2 bar.
During these operations, enable the "Venting" fun-
ctions by setting the "M01" parameter to ON, which lasts
about 18 hours (Parag. 3.9).
System minimum water content.
Minimum water content favours the proper execution of defro-
sting cycles and operation in cooling mode.
To this end, the minimum amount of water to guarantee is 30 li-
tres for any type of system and in any operating mode.
