INFORMATION
Protective functions – "Installer-on-site mode". The
software is equipped with protective functions, such as
room antifrost. The unit automatically runs these functions
when necessary. (If the user interface home pages are off,
the unit will not operate automatically.)
During installation or service this behaviour is undesired.
Therefore, the protective functions can be disabled:
▪ At first power-on: The protective functions are
disabled by default. After 36 h they will be automatically
enabled.
▪ Afterwards: An installer can manually disable the
protective functions by setting [4‑0E]=1. After his work
is done, he can enable the protective functions by
setting [4‑0E]=0.
Especially for UK:
It is a requirement that the boiler is installed and commissioned to
the manufacturer's instructions and the data fields on the
commissioning checklist completed in full.
To instigate the boiler guarantee the boiler needs to be registered
with the manufacturer within one month of the installation.
To maintain the boiler guarantee it is essential that the boiler is
serviced annually by a Gas Safe registered engineer who has been
trained on the boiler installed. The service details should be
recorded on Service Interval Record and left with the householder.

To perform a gas pressure test

1 Connect a suitable gauge on the gas valve. Static pressure
MUST be 20 mbar.
2
2 Select test program " ". See "13.2 To perform a test run on the
gas boiler" [ 4 34]. Static pressure MUST be 20 mbar (+ or –
1 mbar). If the working pressure is <19 mbar, the gas boiler
output will be reduced and the correct combustion reading may
NOT be obtained. Do NOT adjust the air and/or gas ratio. To
obtain sufficient working pressure, gas supply MUST be correct.
INFORMATION
Make sure the working inlet pressure does NOT interfere
with other gas appliances installed.
13.2 To perform a test run on the gas
boiler
The gas boiler has a test run function. Activating this function results
in the activation of the indoor unit pump, as well as the gas boiler
(with a fixed fan speed), without the control functions being actuated.
The safety functions remain active. The test run can be stopped by
pressing and simultaneously or will end automatically after
10 minutes. To perform a test run, switch off the system with the
user interface.
Make sure that the leaving water temperature home page, room
temperature home page, and domestic hot water home page are
turned OFF.
There may be no error on the gas boiler or the heat pump module.
During a gas boiler test run, "busy" will be displayed on the user
interface.
