9. Commissioning

NOTE
High risk of damage: Fill the cylinder before commis-
sioning and connection to the mains.
NOTE
Before commissioning, check the entire water circuit
for leaks.
Leave the device switched off.

Open the top domestic hot water tapping point of

the
system.
Open the cold water inlet on the safety group.

Fill the cylinder until the water runs from the top

tapping point free from bubbles.
Close the domestic hot water tapping point.

In the permissible range between +5 °C and +45 °C in-
take air temperature, the device is primarily in heat
pump operation.
The domestic hot water temperature supplied by the
heat pump can be controlled up to 60 °C.
For a high domestic hot water consumption, the do-
mestic hot water heat pump has a so-called "Comfort"
function . With this function, the heat output is in-
creased if only 1/3 of the remaining cylinder volume is
above temperatures >38 °C.
If a large quantity of domestic hot water is required for
a short time, the domestic hot water heat pump has a
"Turbo" function (can be activated by the user), which
heats up the water quickly to the desired temperature
using the supplementary electric heating (e.g. to
50 °C). This function is deactivated again as soon as
the setpoint is reached (e.g. 50 °C).
