Equipment properties
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.
