You have two options for defining the days for which
your time windows should apply:
1st option
You can enter time windows for individual days.
Example:
Mon
09.00 - 12.00 hrs.
Tue 10.00 - 12.00 hrs.
2nd option
You can combine several days into blocks.
Example:
Mon-Fri
09.00 - 12.00 hrs.
Sat-Sun 12.00 - 15.00 hrs.
Mon-Sun 10.00 - 12.00 hrs.
You can define up to three time windows for each
option.
You can control the hot water temperature in a con-
nected DHW cylinder in the same way using the control-
ler: The time windows you define specify when the hot
water at your desired temperature is available.
However there is no night set back temperature for the
hot water generation.Hot water generation is switched
off at the end of a time window.
Heating curve
The heating temperature is controlled indirectly by
means of a heating curve. The heating curve shows the
relationship between the outside temperature and the
flow temperature.
The flow temperature is the temperature of the heating
water as it leaves the boiler.
You can set the heating curve individually for each hea-
ting circuit.
You have the option of selecting various heating curves
to match the control system optimally to your apart-
ment and to the heating installation.

Fig. 3.4 Parallel offsetting of the heating curve
If heating curve 1.5 is selected and 22 °C rather than 20
°C is specified as the room target temperature, the hea-
ting curve is displaced as shown in
Fig. 3.4 . The heating
curve is displaced in parallel along the 45° axis accor-
ding to the value of the room target temperature. This
means that when the outside temperature is 0 °C, the
controller provides a flow temperature of 67 °C.
i
Your expert technician will have made the
required basic setting of the heating curve
while installing the heating
system.
