Purging check programme:
The boiler circulation pump is cyclically actuated.
The heating circuit is purged via the automatic air
vent.

After successful ignition, the product is operated at
maximum heat input.
P.02
Minimum load check programme:
After successful ignition, the product is operated at
minimum heat input.

Note
If the product is in error condition, you cannot start
any check programmes. You can detect an error
condition by the fault symbol shown in the left
bottom corner of the display. You must first reset.
To terminate the check programmes, you can press (

Reading off the filling pressure
The product's supply pipe is equipped with an analogue
pressure gauge, a symbolic bar graph display and a digital
pressure gauge.
▶
To read off the digital filling pressure value, press the
button twice.
If the heating installation is full, in order to ensure that it op-
erates smoothly, the indicator on the pressure gauge must
point to the upper half of the grey area or to the middle of the
bar graph display on the display (marked by the dashed limit
values) when the heating installation is cold. This corres-
ponds to a filling pressure of between 0.1 MPa and 0.2 MPa
(1.0 bar and 2.0 bar).
If the heating installation extends over several storeys,
higher filling pressures may be required to avoid air entering
the heating installation.
7.10
Preventing low water pressure
To prevent damage to the boiler that is caused by a filling
pressure that is too low, the boiler is fitted with a water
pressure sensor. If the filling pressure falls below 0.1 MPa
(1.0 bar), the product indicates low pressure by displaying a
flashing pressure value. If the filling pressure falls below 0.05
MPa (0.5 bar), the product switches off. The display shows
F.22
.
▶
Top up the heating water to start the product up again.
The pressure value flashes in the display until a pressure of
0.11 MPa (1.1 bar) or higher has been reached.
▶
If you notice frequent drops in pressure, determine and
eliminate the cause.
