DHW is heated by the heat pump and immersion
heater to reach the standard DHW temperature as
quickly as possible.
You can adjust the standard DHW temperature at any
time.
As soon as the standard DHW temperature has been
reached, the heat pump control unit switches back to
the operating program that was previously activated.
To end the "BOOST" operating program early, select a
different operating program.
Note
■ After starting, the heat pump will always run for a
specified minimum runtime.
■ Operating an immersion heater results in higher
power consumption.
