2.8 Product description
Basic components of boiler:

Boiler body

Device frame and casing

Control unit

Contactors (switches)

Safety circuit (automatic fuses with trigger)

Processor board and boiler electronics

Safety valve
Boiler can be installed as integral part of the central heating system,
floor heating, hybrid, or accumulation
Boiler is compounded of weld housing of steel tin with thermal
insulation. The boiler is fixed on the wall by supplied mounting set.
Installed heating insulation in boiler jacket reduces loss of the heat,
and also protects against noise.
Safety elements (vent valve, managing surface fuse and
temperature safety limitation) are mounted at the top of
Depending on the type of the boiler, different elements of
heating are used. Heating elements' performance can be
adjusted according to grades.
Different performance grades sets can be obtained through
control panel. Number and division of performance grades are
visible from technical data (see chapter
