2.2 What do the following
temperatures mean?
Desired temp. is the temperature to which
you want to heat or cool the living rooms.
Set-back temp. is the level below which
the temperature in the living rooms does
not fall when outside of the time periods.
2.3 What is a zone?
A building can be divided into multiple
areas, which are known as zones. A dif-
ferent requirement can be placed on the
heating installation in each zone.
Examples for dividing into zones:
– Underfloor heating (zone 1) and a ra-
diator system (zone 2) are available in
one building.
– A building is made up of several self-
contained residential units. Each resid-
ential unit has its own zone.

Desired temper-
ature
You can divide a day up into several time
periods (1) and (2). Each time period can
comprise an individual start time and end
time. The time periods must not overlap.
You can assign a different desired temper-
ature (3) to each time period.
Example:
16:30 to 18:00; 21 °C
20:00 to 22:30; 24 °C
The living rooms are heated to the desired
temperature within the time periods. In the
times outside of the time periods (5), the
living rooms are heated to the lower set-
back temperature (4) that is set.
