Application
The VRC 430f is a weather compensator controller for
heating and water heating.
"Weather compensator" means: the VRC 430f increas-
es its heating output at lower outside temperatures
and reduces its heating output at higher outside tem-
peratures. The outside temperature is measured by a
separate sensor, mounted outdoors, and the signal is
transmitted to the VRC 430f.
The room temperature depends only on your preset
values. The influence of the outside temperature
is compensated for.
You can use the VRC 430f to specify different room tar-
get temperatures according to the time and day.
In automatic mode, the VRC 430f controls your heating
based on these settings (see Fig. 0.1).
You can also define daily periods during which water is
heated using the VRC 430f.

The VRC 430f can also be used to control the following
accessory components:
– Circulation pump for the hot water generation in con-
junction with a multi-functional module VR 27
– Conventional hot water cylinder
– Vaillant layer cylinder actoSTOR
– Second heating circuit using the Vaillant Mixer
Module VR 61
– Solar system using the Vaillant Solar Module VR 68
The VRC 430f can be part of a new heating and water
heating installation or can be retrofitted in an existing
installation. The appliance must have an eBUS interface.
eBUS is a communication standard for data exchange
between the components of heating technology.
