comfort:
Auxiliary heating supplies the temperature
level that the compressor cannot provide
(approx. > 58 °C cylinder temperature)
CH only:
DHW heating by means of auxiliary heating
only, e.g. in emergency operation (if "no CH" was
previously activated, a max. DHW temp. of approx.
58 °C applies; if "CH" was activated, the max. DHW
temp set in C6 applies
CH start at:
Setting the degree minutes until the
auxiliary heating starts, added to the degree minutes
for compressor start.
Example: -600°min plus -120°min
=> start at -720°min.

Start legionellas:
The preset time of day determines
when the anti-Legionella function will start.
The anti-Legionella function is carried out by the
auxiliary heating on the preset day of the week, at
the preset time, if the auxiliary heating has been ac-
tivated.
For this purpose, the controller sets the flow set-
point to 76 °C/74 °C (2K hysteresis). The anti-Le-
gionella function is terminated when the current
flow temperature at the cylinder has reached 73 °C
for a duration of at least 30 min, or after 90 minutes
if 73 °C is not reached (e.g., if hot water is drawn
during this period).
