System components
Thermic valve
Laddomat or an equivalent product should always be installed
between the boiler and accumulator tank. Function is described
in detail on page 17. Note that warranty is void if it is not used!
Shunt control
Installation of a shunt control on the radiator
circuit is always recommended. The software in the boiler is
prepared for shunt control. The shunt motor is mounted on the
shunt valve and regulates the temperature using an indoor sen-
sor, outdoor sensor or both.
Expansion vessel
The expansion vessel can normally withstand a pressure of 88
psi
bar. Maximum operating temperature is 210°F. The volume of
a pressure vessel is 10-12 % litres depending on the system's
overall volume. An open vessel must contain 5 % of the total
system's volume. When planning for size, keep in mind the
radiator volume and the volume of the boiler. A pressure vessel
must have a pre pressure of 3 psi above the highest radiator.
Safety valve
The safety valve opens if the pressure reaches 44 psi. When
the valve opens, excess water drips out and the system pres-
sure is reduced. The pressure must under no circumstances
exceed 44 psi.
Shunt valve
The shunt valve is fitted to the radiator circuit. Its task is to mix
accumulator tank water with recycled water from the radiators
to achieve the correct temperature of the radiator water. For
the installation of the shunt automatic system, please follow the
supplied description.
