Note
The actual reading on the digital pressure
gauge should ideally be 0,05 MPa (0,5 bar)
plus an additional pressure corresponding
to the highest point of the system above the
base of the boiler – 10 m head equals an ad-
ditional 1 bar reading on the pressure gauge.
The minimum pressure should not be less
than 0,1 MPa (1 bar) in any installation. If
the system is to be treated with an inhibitor it
should be applied at this stage in accordance
with the manufacturer’s instructions.
8. Install the front casing. (→ Page 18)
9.11 Checking leak-tightness
▶ Check the gas pipe, the heating circuit and the hot water
circuit for leak-tightness.
▶ Check that the air/flue pipe has been installed correctly.
Condition: Room-sealed operation
▶ Check whether the vacuum chamber has been closed
tightly.
9.11.1 Checking the heating mode
1. Activate the heating mode on the user interface.
2. Turn all thermostatic valves on the radiators until they
are fully open.
3. Allow the product to operate for at least 15 minutes.
4. Fill and purge the heating installation. (→ Page 28)
5. Call up the status codes. (→ Page 26)
Status codes – Overview (→ Page 45)
◁ If the product is working correctly, the display shows
S.04.
10 Adapting the unit to the heating
installation
You can reset/change the system parameters.

10.1 Setting the burner anti-cycling time
To prevent frequent switching on and off of the burner and
thus prevent energy losses, an electronic restart lockout
is activated for a specific period each time the burner is
switched off. The burner anti-cycling time is only active for
the heating mode. Domestic hot water mode during a burner
anti-cycling time does not affect the timing element.
10.1.1 Setting the burner anti-cycling time
1. Navigate to diagnostics code D.002 in the installer level
and confirm by pressing .
2. Set the burner anti-cycling time and confirm by pressing
.

time
▶ Press .
10.2 Setting the pump output
The product is equipped with a speed-regulated high-effi-
ciency pump, which adjusts independently to the hydraulic
conditions of the heating installation.
If you have installed a low loss header in the heating install-
ation, you should switch off the speed regulation and set the
pump output to a fixed value.
▶ If required, change the setting of the pump speed, which
depends on the operating mode, under diagnostics code
d.14.
