Assembly

The controller can be mounted directly to the wall in the
wall mount or as a remote control device with the VR 55
mounting box (accessory).

The controller is supplied with one of the following
external sensors:
VRC 693: connected to the controller via a 2-core cable,
VRC DCF:

connected to the controller via a 3-core cable.

4.1 Basic

installation

steps

1. Preparation:

Read the installation instructions.
Check the scope of delivery.

2. Installation of the controller:

Fit the wall mount and the central controller
Fit the external sensor (VRC DCF or VRC 693)
Carry out the electrical installation

3. Commissioning:

Make the basic settings on the central controller
Make the system-specific settings.

4. Handing over the appliance to the owner

A few comments regarding this:
The controller enables the control of heating installa-
tions with different components.
To adapt the control system to the conditions on site,
you must perform the electrical installation according to
the components required in the system. Further infor-
mation on the electrical installation can be found in
Chapter 5.

Accessories

You can use the following accessories to extend the
modular bus control system:

VR 55 mounting box

The range of accessories includes a mounting box, with
which the operating unit can be used as a remote cont-
rol device with the ProE terminal strips, which means
regardless of where the central wall mount is installed.
Communication is effected via the eBUS. A bezel is sup-
plied with the accessories which can be plugged into the
central wall mount instead of the control unit.

VR 60 mixer module

The heating system can be extended by two mixer cir-
cuits using the mixer module. A maximum of six mixer
modules can be connected.
A unique bus address is set on the VR 60 using the
rotary switch. The heating programmes and also all the
required parameters are set via the central controller
using eBUS. All heating circuit connections (sensors,
pumps) are made directly to the mixer module with
ProE plugs.

VR 30 modulating bus coupler

The modulating bus coupler allows the main controller
to communicate with several Vaillant boilers. If more
than two heaters are to be connected in cascade, a bus
coupler is required for each heater to connect it to the
eBus (Western socket). Up to eight VR 30 bus couplers
can be connected.
The bus coupler is installed directly in the boiler's elect-
ronic box; communication with the controller is effected
via the eBUS. A unique bus address is set on the VR 30
using the rotary switch. All other settings are made on
the central controller.

VR 31 switching bus coupler

The VR 31 bus coupler allows the VRC 630 central con-
troller to communicate with a switching heating appli-
ance. With this combination, the communication
between the controller and the boiler basically takes
place via the eBUS. When a cascade is constructed, a
separate bus coupler is required for each heater. Up to
six bus couplers can be connected.

VR 32 modulating bus coupler

The VR32 modulating bus coupler allows the main con-
troller to communicate with several Vaillant eBUS boi-
lers. If several boilers are to be cascaded, a bus coupler
is required from the 2nd boiler to establish the connec-
tion between the eBUS and the boiler (Western socket).
You can connect up to eight VR 32s.
The bus coupler is installed directly in the boiler's elect-
ronic box; communication with the controller is effected
via the eBUS. You set a unique bus address on the
VR 32 using a rotary switch. All other settings are made
on the main controller.
