Safety devices and controls.
System adjustable by-pass (2).
Guarantees the circulation of water in the primary circuit
(between flow and return) also when the high resistance of the
system does not allow it.
It is mounted on the flow manifold unit (1) and can be adju-
sted by a screw that can be accessed from the lower part of the
valve support plate.
System filing unit (3).
It is a ball valve positioned between the boiler circuit and the
domestic cold water inlet that allows to pressurise the CH
system.
The valve is connected to a filling fitting (4), which is then
connected to the motorised 3-way valve unit.
System pressure switch (5).
Detects the pressure inside the primary circuit.
Its seat is in the flow manifold unit (1) and is coupled to a
micro switch that prevents functioning of the burner when
the pressure detected is below 0.3 bar.
Prevents overheating of the main heat exchanger.
Automatic air vent valve (6).
Allows the automatic expulsion of the gaseous substances that
may be present in the boiler circuit.
It is mounted on the pump flow directly on the hydraulic
unit.
3 bar safety valve (7).
Prevents the safety pressure in the primary circuit from being
exceeded (3 bar).
It is engaged in the front part of the flow manifold unit (1)
and is fixed onto the external side using a clip.
Its intervention causes water to escape from the flow pipe.
System expansion vessel (8).
It compensates the volume variation consequent to heating
the water, thus limiting the pressure variations.
It has a capacity of 10 litres (useful 7.1 litres) and a factory-set
pressure of 1.0 bar.
It is positioned in front of the storage tank in the area in front
of the appliance.
