3.2 Storage
The thermostatic valve set must only be
stored under the following conditions:
• Do not store in open air, keep dry and
free from dust.
• Dot not expose to aggressive fluids or
heat sources.
• Protect from
mechanical agitation.
• Storage temperature: –20°C up to +60°C
• Max. relative humidity of air: 95 %
3.3 Packaging
Packaging material is to be disposed of in
an environmentally friendly manner.

5 Function

5.1 Functional description

The thermostatic valve "AV 9" is fitted with
an infinitely presettable valve insert and
allows for a trouble-free, exact adaptation of
the flow rates to the required heat demand.
The radiator lockshield valve "Combi 2"
with proportional fine setting and isolating
facility allows for the removal of the radiator
without draining the system.
Hydronic balancing of the heating system
can be carried out with the help of the
presetting of the thermostatic valve or the
radiator lockshield valve.
This way, a constant warming up of all
radiators in a heating system is guaranteed.
Note:
To avoid increased differential pressures at
the thermostatic valves and disturbing flow
noises, installation of automatic differential
pressure regulators
circulation pumps in the central supply
risers is recommended.
The thermostat "vindo TH" together with
the thermostatic valve is a proportional
controller working without auxiliary energy.
It regulates the room temperature by varying
the volume flow of the heating water.
