3.28 PARAMETERS FOR FILLING IN THE
ASSEMBLY SHEET.
In case you should wish to install an assembly,
starting from the Victrix 12X-20X TT 2 ErP boil-
er, use the assembly charts in fig. 3-18 and 3-21.
For correctly filling in, enter the figures shown in
tables fig. 3-17 and 3-20 (as shown in the facsim-
ile assembly sheet fig. 3-16 and 3-19).
Facsimile for filling in room heating system assembly chart.
The remaining values must be obtained from
the technical data sheets of the products used
to make up the assembly (e.g. solar devices, in-
tegration heat pumps, temperature controllers).
Use sheet fig. 3-18 for “assemblies” related to
the heating function (e.g.: boiler
+
temperature
controller).
Use sheet fig. 3-21 for “assemblies” related to the
domestic hot water function (e.g.: boiler
+
solar
thermal system).

The energy efficiency of the package of products provided far in this fiche may not correspond
to its actual energy efficiency once installed in a building, as the efficiency is influenced by fur
-
ther factors such as heal loss in the distribution system and the dimensioning of the products in
relation to building size and characteristics.
