Overview of the heating circuit without a room
sensor
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 6.6.3 "
The heating curve"), the optional room
sensor and the time window settings (see chapter
6.6.2 "
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.
Switching between heating and reduced operation
takes place automatically when the button is used
in the user interface to select the [Timer] operating
mode.
The operating modes are also manually adjustable.
Heating mode is activated with the button, and
reduced operation mode with the button. See
chapter 6.6.1 "
Operating elements".
