11.5 Legionella elimination

To eliminate any occurrence of legionella bacteria, the
tank's water temperature is raised to 65° once a week.
Legionella bacteria die when the temperature exceeds
50-60° C.
This takes place automatically with a warm-up start at
2 am every Monday morning.
The function can be switched off if desired.
Go to "Advanced settings" / "General settings" hold the
button for 5 seconds.
Proceed to "Hot water settings" / "Per extra VV temp"
YES = function ON, NO = function off.

11.6 Operation with heat elements only

There is the possibility to set the function "Heat elements only" in case of e.g. malfunctions
in the compressor module.
The compressor is then not run at all and all heat is produced by the additional elements.
If you have selected "Heat elements only", the
attached picture is shown under "Operating
information"
Go to "Advanced settings" / "General settings"
hold the button for 5 seconds.
Proceed to "Basic settings" / "Heat elements
only". Change NO to YES.

11.7 Operation with fan off

When the house is under construction or major renovation work is in progress,
you can run the heat pump as an electric boiler without the fan running. In this
way, dust and dirt avoid being sucked into the heat pump, which can damage
vital parts of the compressor module and get stuck in the filter.
Turn off the fan by:
Go to "Advanced settings" / "General settings" hold the button for 5 seconds.
Proceed to "Fan settings" / "Fan off". Change NO to YES.
The control will automatically switch over to "Heat elements only" operation.
