Operating instructions
hNote
Have your expert technician explain the operati-
on of the VR 81 remote control unit once the in-
stallation is complete. This will prevent involun-
tary changes to the settings.
Note
Also read the operating manual for the VRC 430
controller. This describes how important
parameters of your heating system
can be adjusted (e.g. time window). An
explanation of technical terms and important
functions is provided in alphabetical order at the
end of this document.
1 Appliance features
The VR 81 remote control unit is a wired remote control
unit for a heating circuit and is used in combination with
the VRC 430 controller. Communication with the boiler is
achieved via a 2-lead bus line (eBUS).
You can adjust or modify the main functions via the VR 81
remote control unit (operating mode, target room
temperature).
Only one VR 81 remote control unit can be used.
Product specifications
– eBUS interface
– Symbol display
– Operation using a single dial based on the "Turn and
Click" principle
- The remote control unit can be mounted separately on
the wall
2 Safety

recognised expert technician who is also responsible for
ensuring that existing standards and regulations are
observed.
We accept no liability for any damage caused by failure to
observe these instructions.

3.1 Intended use
The VR 81 remote control unit is a state-of-the-art device
which has been constructed in accordance with the
standard safety regulations.
Even so, inappropriate or non-intended use may adversely
affect the appliance and other material assets.
A mixed or unmixed heating circuit can be controlled
remotely by the VRC 430 controller in conjunction with a
Vaillant boiler and eBUS interface using the VR 81 remote
control unit.
Any other use or extended use is considered to be use
other than intended. The manufacturer or supplier is not
liable for any resulting damage. The owner alone bears
any risk.
Intended use also includes observance of the operating
and installation instructions and all other documents also
have validity.
3.2 Ambient conditions
The VR 81 remote control unit may only be installed in dry
rooms.
Observe the following where the "Switch-on room temp."
function for the remotely controlled heating circuit is ac-
tivated at the VRC 430 controller:
– the VR 81 remote control unit must not be covered by
furniture, curtains or other objects;
– all radiators in the room where the VR 81 remote
control unit is fitted must be fully on.
Your heating engineer will advise you whether the
"switch-on room temp." is activated.
3.3 Care
hNote
Do not use abrasive materials or cleaning agents
that could damage the operator control
elements, parts of the casing or display.
Clean the casing of the VR 81 remote control unit with
a damp cloth.
