Vaillant ambiSENSE VR 920 Betriebsanleitung Seite 10

1 Product overview
1.1.1 Influence on the VRC 700
The heating circuit that is controlled by ambiSENSE is automatically set to the "Day mode" operating mode. The maximum
target temperature for all rooms is forwarded to the VRC 700. The heat demand control is adjusted via the boiler. If the tar-
get temperatures of all of the rooms that are controlled by ambiSENSE are reached, the heating circuit that is controlled by
ambiSENSE is automatically set to "Off" in order to save energy. If ambiSENSE is activated, the time programmes and tar-
get temperatures for the heating circuit that are displayed on the VRC 700 are no longer valid and are overwritten every 15
minutes. Time programmes and target values for the heating circuit can be individually set for each individual room using the
VRC 700 app.
1.1.2 Heating circuits controlled by ambiSENSE
If ambiSENSE is installed, the heating circuit that is controlled by ambiSENSE is automatically configured for the individual
room control (see the influence on the VRC 700).
–
For systems with one heating circuit, it is automatically controlled by ambiSENSE when ambiSENSE is installed.
–
For systems with two heating circuit, the heating circuit that is controlled by ambiSENSE is assigned depending on an
underfloor heating system:
–
If no underfloor heating is present, both heating circuits are automatically controlled by ambiSENSE.
–
If an underfloor heating system is present, the first heating circuit is controlled by ambiSENSE. The second heating
circuit is controlled by the VRC 700.
