Small motor for 3-way valve (optional) for cen-
tral heating versions only.
A small electric motor (1) connected to the 3-way valve group
(2) and blocked using a relevant clip that allows, according
to request (
DHW or CH
), to introduce the boiler water
into the heating system or into the domestic hot water heat
exchanger(
Separate 80, 105, 120 and 200 litre storage tank
unit
).
This depends on the position of the shutter (4) which, closes
the passage towards the system opening it at the same time
towards the domestic hot water heat exchanger (
DHW position
)
or vice versa (
CH position
).
The shutter (4) is moved into both positions by powering the
motor (1) (
optional
).
The hydraulic part is made up from a brass unit (2).
Operation in central heating phase.
The hydraulic unit is always positioned in the system central
heating phase, the shutter (4) contrast spring (3) is not com-
pressed (
central heating position
), keeping the passage towards
the domestic hot water heat exchanger closed (
storage tank coil
)
and keeping the passage towards the system flow open.
Both the spring (3) and the shutter (4) are situated inside the
brass 3-way valve group body (2).
Operation in central domestic hot water phase.
The small electric motor (1) pushes the stem (5) to which the
shutter is connected, (4) which closes the passage towards the
system and opening it at the same time towards the domestic
hot water heat exchanger (
storage tank coil
). The shutter (4) con-
trast spring (3) is compressed (
domestic hot water position
).
Both the spring (3) and the shutter (4) are situated inside the
brass 3-way valve group body (2).
