13.2 DIAGRAM 02
(TECHNICAL H
In this type of circuit, technical H2O storage tank is
managed by the product thanks to a contact or im-
mersion probe (not provided) to be connected to
the back side of the appliance.
The new stand-by screen is shown below.

scroll button. Any change in temperatu-
re settings is confirmed either automatically - within 3
seconds from the last change – or by pressing
button. An acoustic signal will confirm the change.

the probe. Temperature is not editable.
Ihe operation is the same as the one of the basic dia-
gram, with the only difference that, with this diagram,
the product exchanges directly in the technical wa-
ter storage tank. As soon as the set temperature is
reached, the appliance switches to ECOSTOP status
and then restarts if the temperature drops below a
re-ignition value (Delta restart settable by the installer
at time of testing).
13.3 DIAGRAM 03
(DHW + TECHNICAL H
The following diagram combines the functions of the
other diagrams described previously and is suggested
to those having a technical water storage tank (hot
water tank) without the internal coil for domestic wa-
ter use. In this type of circuit, the DHW storage tank is
managed by the appliance by means of a contact
or immersion probe (not provided) to be connected
on the back side of the product. The same applies
for the management of H
pliance manages the heating by means of a con-
tact or immersion probe (not provided), always to be
connected on the back side of the product.

The operation is the same as the one of the basic dia-
gram, with the only difference that, with this diagram,
the product exchanges directly in the DHW storage
(priority); when the set temperature is reached, the
three-way valve changes its position and the ap-
pliance begins to exchange in the technical water
storage (hot water tank). As soon as the set tempera-
ture is reached, the appliance switches to ECOSTOP
status and then restarts if the temperature drops be-
low a re-ignition value (Delta restart settable by the
installer attime of testing).
The three-way valve redirects itself again to the DHW
storage tank when:
- it is required by the storage tank itself;
- it is required by the flow switch
From ECOSTOP or H
restarts considering the requests of one of the two
storage tanks.
By setting SUMMER mode, the three-way valve
remains fixed, allowing heat produced by the
appliance to be transferred only inside the DHW
storage. As soon as this condition is reached, the
product switches to ECO STOP mode.
