Preliminary checks
a
WARNING
– Should it be necessary to access the areas in the
bottom part of the appliance, make sure that the
system components and pipes are not hot (risk of
burning).
– Before replenishing the heating system, put on
protective gloves.
Commissioning of the
OPEN HYBRID SMART
boiler must be
carried out by professionally qualified Personnel after which the
boiler can operate automatically. It may however be necessary
for the User to start the appliance autonomously without
involving a technician: for example, after a holiday . In these
cases certain checks and the following operations must be
carried:
– check that the gas isolation and water system valves are open
– using a pressure gauge (1), check that the heating system
pressure when cold is
1-1.2 bar
. If this is not the case, open
the filling valve (2) and restore the heating system pressure
until the pressure gauge (1) shows a reading of
1-1.2 bar
– close the filling valve (2).

Ignition
After having carried out the preliminary checks, perform the
following to start the boiler:
– set the main system switch to "ON"
ON
Fig. 3
– on the display, check that the operating mode on the display
is "SUMMER”
l
and if necessary select it by pressing and
holding the button
s
for at least 1 second. the value of the
delivery sensor detected at that moment will appear on the
display
– open one or more than one hot water tap. The boiler will work
at maximum power until the taps are closed.
Once the boiler has been commissioned in "SUMMER mode"
l
"WINTER mode"
n
can be selected by pressing and holding the
button
s
for at least 1 second. the value of the heating water
temperature detected at that moment will appear on the display.
In this case it is necessary to adjust the air thermostat/s to the
required temperature or if the system has a chrono-thermostat,
check that this is "active" and adjusted.

Adjusting the delivery temperature
If the boiler delivery temperature is to be increased or decreased
it is possible to act on the
t
knob on the control panel rather
than having to modify the specific parameters. The temperature
can be set to between 20 and 80°C.

Adjusting the domestic hot water
temperature
If the domestic hot water temperature is to be increased
or decreased, act on the
r
knob on the control panel. The
