Independent of the standard DHW tem-

perature (Set temperature 2) for DHW
heating.

Enabling electric heater for DHW heating

If the heat pump on its own cannot ach-
ieve the selected DHW temperature, an
instantaneous heating water heater
(accessory) can be started automatically
to boost DHW heating.
The constant use of an instantaneous
heating water heater results in higher
power consumption, which therefore
requires it to be enabled.
■ Have you set the required time pro-
gram?
For settings, see page 29.
■ By selecting the operating status
"Temp. 2" in the DHW time program,
you can heat the DHW to that value
(see page 29).
■ The "Set temperature 2" is the set
value for heating the DHW once (see
page 31) and for the manual opera-
tion (see page 43).
