In each set period, the desired temperature that you set
in the "Desired temperatures" function applies.
Within the period, the controller switches to Comfort
mode and the heating circuit heats the connected rooms
to the desired "Day" temperature.
Outside the period, the controller switches to the mode
that the heating engineer has set: Frost protection, Eco-
nomical, or Night temperature (
¬
Section 5.2.1 ).

Preparation
In each set period, the desired hot water temperature
that you set in the "Desired temperatures" function
applies.
Within the period, the hot water is available at the tem-
perature set by you. If, during the period, the cylinder
temperature is 5 °C lower than the desired hot water
temperature, the domestic hot water cylinder is again
heated to the desired hot water temperature. At the end
of a period, the controller switches the hot water pro-
duction off, until the start of the next period.
For circulation:

Circulation
The set periods determine the operating times for circu-
lation. Within the period, circulation is activated. Outside
the period, circulation is deactivated.
Coordinate the periods for circulation with the periods
for hot water production. If, for example, the period for
hot water production starts at 05:00, then the period
for circulation should start 30 minutes later at 05:30.
