Overview of the heating circuit when a room
sensor is installed
The following graphic shows a heating circuit with
underfloor heating. If the heating circuit is equipped
with radiators a radiator also appears in the overview.

1 Operating condition and information.
A description of the operating conditions can be
found in the integrated Help menu by pressing the
button.
2 Producer for the heating circuit

In this menu, the heating times and the heating
curve can be adjusted, for example.

Overview of the heating circuit without room
sensors
In the overview, a temperature slider appears, rather
than the measured room temperature.

Mode of operation
If the heating circuit is turned on ( ), heat is
supplied on the basis of the time windows set. The
temperature is controlled with the heating curve (see
chapter 7.6.3 "
The heating curve"), the optional room
sensor and the time window settings (see chapter
7.6.2 "
Setting the heating time slots").
During a time window, the heating circuit is in heating
mode. If a room sensor is installed, this regulates the
heating circuit so that the set room temperature is
achieved. If a room sensor is not installed, the heating
circuit is controlled with the heating curve for the
heating mode. Accurate temperature control is
therefore difficult.
Outside the set time slots, the heating circuit is in
reduced operation mode. This means that the room
sensor only regulates to the set reduced room
temperature [Set-back temperature outside the time
window]. Without a room sensor, the heating circuit is
controlled with the heating curve for the reduced
operation mode.
