4 Operation
4.1 Starting up the product
4.1.1 Opening the isolator devices
1. Ask the competent person who installed the product to explain to you
where these isolator devices are located and how to handle them.
2. Open the gas isolator cock fully.
3. Check that the heating installation flow
and return service valves are open, if
such service valves are installed.
4. Open the cold water stop valve. To
check, you can turn on a hot water
valve and see whether water is escaping there.
4.1.2 Switching on the product
▶ Switch on the product via the main
switch installed on-site.
4.2 Basic display
The filling pressure in the heating installation and the operating mode are shown in
the display's basic display.
To return to the basic display:
– Wait more than five seconds without
pressing any buttons.
If a fault message is present, the basic
display switches to the fault code.
4.3 Checking the heating system
pressure
1. Once a month, check that the pressure
in the central heating system, which
is displayed on the user interface, is
between 0.05 MPa and 0.27 MPa
(0.5 bar and 2.7 bar).
◁ If the filling pressure is correct, no
action needs to be taken.
▽ If the filling pressure is too low, add
more water to the heating installation.
Note
If the heating flow temperature
is shown in the display, press
and hold the and buttons
at the same time for longer than
five seconds, or temporarily
deactivate heating mode in
order to display the pressure.
2. Fill the heating installation.

4.4 Filling the heating installation
Caution.
Risk of material damage due
to heating water that is extremely calciferous or corrosive or contaminated by chemicals.
Unsuitable tap water damages
the seals and diaphragms,
blocks components in the
product and heating installation
through which the water flows
and causes noise.
▶ Only fill the heating install-
ation with suitable heating
water.
Note
The competent person is responsible for filling the heating installation the first time, any subsequent
top-ups and the water quality.
The operator alone is responsible for topping up the water in the
heating installation.
1. Open all radiator valves (thermostatic
radiator valves) of the heating installation.
2. Slowly open the filling cock, as shown
to you by the competent person.
3. Fill with water until the required filling
pressure is reached.
4. Check the filling pressure in the
display.
5. Close the filling cock after filling.
4.5 Selecting the operating mode
Note
The unit is always activated with
the preselected operating mode.
▶ Press repeatedly until the display
shows the required operating mode.

4.8 Product settings
Note
The sequence in which the available settings are shown depends
on the operating mode selected.
If the Domestic hot water + Heat-
ing operating mode is selected,
the hot water temperature must be
confirmed in order to set the flow
temperature of the heating.
1. Press the or button to set the temperature.
2. Press the button to confirm.
4.9 Switching the product to
standby mode
▶ Press the button for less than three
seconds.
