4.3 System
configuration
The Vaillant solar heating system enables various sys-
tem configurations and control types in accordance with
the connection wiring diagrams 1 to 6 (
¬
section 6.8
).
i
Single-channel eBUS controllers are not suitable
for this system configuration.
Wiring
If you use an eBUS-compatible Vaillant gas-fired wall-
hung boiler, you can use one of the Vaillant Control Cen-
tres to wire the system.
For all other gas-fired wall-hung boilers, you can use a
standard cabling box.
4.3.1
Vaillant controllers and their basic functions
VRS 560/2 solar controller
The auroMATIC 560/2 solar controller is a differential
temperature-controlled control set for solar-aided hot
water production with demand-controlled primary heat-
ing for Vaillant gas-fired wall-hung boilers.
The control set is a fully equipped system for solar heat-
ing systems with a collector array and cylinder.
If a solar yield temperature sensor (VR 10, supplied with
controller) is connected, the solar yield can be recorded.
Control Centre
A Vaillant Control Centre provides a system solution
which allows the Vaillant dual-channel eBUS controller
(low-voltage) to be used in the English market with
valves and domestic hot water cylinders with conven-
tional 230 V cylinder thermostats.
The Control Centre sends the information on the heat
requirement of the cylinder to the Vaillant ecoTEC gas-
fired wall-hung boiler. The gas-fired wall-hung boiler
decides whether a hot water requirement needs to be
met and sends a signal to control the 230 V valves via
the Control Centre.
The gas-fired wall-hung boiler can thus hold different set
temperature values for heating mode and for hot water
handling.
A Control Centre can be used to integrate commonly
available 230 V S plan or Y plan components into the
Vaillant eBUS system.
VRC weather compensator
(VRC 430, VRC 430f, VRC 470, VRC 470f)
A VRC controller controls the solar heating system in a
weather-compensated and time-dependent manner with
or without hot water production/a circulation pump in
conjunction with a Vaillant gas-fired wall-hung boiler
with an eBUS interface and the Vaillant VR 68/2 solar
module.
Solar module VR 68/2
The VR 68/2 solar module integrates a solar heating sys-
tem into the control concept of a VRC controller. In con-
junction with a VRC controller , various solar heating
system configurations can be implemented and the solar
yield recorded. You can combine the VR 68/2 solar mod-
ule with a VR 61/2 mixer module in a solar heating sys-
tem.
VR 61/2 mixer module
The VR 61/2 mixer module is a system component which
controls a cylinder charging circuit or circulation pump
in conjunction with a VRC controller.
You can use the VR 61/2 mixer module to control a solar
heating system for the heating of potable water in conjunc-
tion with a VRC controller and the VR 68/2 solar module.
