2 Description of the appliance
The Control Center VR 65 offers a solution to allow
Vaillant low voltage ‘eBUS’ controls to be used with the
traditional 230 V zone valves and DHW storage cylinder
in the English market.
Information about the heat required by the cylinder is
forwarded by the Control Center VR 65 to the Vaillant
ecoTEC heating appliance. The boiler then decides
whether a hot water request has to be fulfilled and
sends a signal to position the 230 V zone valves via the
VR 65.
In this way, the boiler can store different target temperatures for heating and warm water operation.
Standard 230 V components can be integrated into the
Vaillant eBUS system via the Control Center VR 65.
3Installation Instructions for Control Center VR 65
2 Description of the appliance
3 Safety instructions and regulations
The following components can be connected
- 230 V 3-port mid-position valve
- 230 V cylinder thermostat
or alternatively
- 2 x 230 V 2-port zone valves
- 230 V cylinder thermostat
When Vaillant uniSTOR cylinder is installed, the NTC sensor VR 10 supplied with the VR 65 can be used instead
of the 230 V cylinder thermostat.
This will then allow the cylinder temperature to be set at
the Vaillant ecoTEC boiler or at the Vaillant VRT 360 or
VRC 400 control.
The cylinder temperature can also be set remotely via
vrnetDIALOG.
2.1 Data badge
The data badge is on the inside of the VR 65 Control
Centre housing cover.
2.2 CE label/conformity
The CE label documents that the Control Center VR 65,
in connection with Vaillant condensation boilers, fulfils
the basic requirements of the following guidelines:
- Electromagnetic compatibility directive (Guideline 89/
336/EEC of the council)
- Low voltage directive (73/23/EEC)
2.3 Intended use
The Control Center VR 65 is a state-of-the-art appliance
which has been designed in accordance with recognised
safety regulations. Nevertheless, dangers to the life and
limb of the user or third parties can still occur or the
appliance or other material assets may be impaired in
the event of improper use or use for which the appliances are not intended.
The Control Center VR 65 is an eBUS system component.
It is responsible for the communication between the
DHW cylinder, the boiler and external 230 V 2- or 3-port
valves.
Any other use or extended use is considered to be
improper use. The manufacturer/supplier is not liable for
any resulting damage. The user alone bears any risk.
Intended use includes the observance of the installation
manual.
3 Safety instructions and regulations
The Control Center must be installed by a suitably qualified heating engineer, who is responsible for observing
all relevant standards and regulations.
We accept no liability for damage caused by non-observation of these instructions.
3.1 Safety instructions
Danger!
Risk of death from electric shock through contact with live connections!
Isolate the mains power supply before working
on the unit, and ensure that the power cannot
be accidentally restarted.
Using the mains switch on the VR 65 or on the
heating appliance is not sufficient to isolate all
terminals of the system.
3.2 Regulations
All wiring must be in accordance with Building
Regulations Part P, current IEE regulations, and must be
carried out by a competent person.
Standard wires must be used for wiring.
Minimum cross-section of wires:
- Power supply 230 V (connection cable
to pumps or Control Center) 1.5 mm
- Extra-low voltage supply
(sensor or bus wires) 0.75 mm
Do not exceed following maximum wire lengths:
- Sensor connection 50 m
- Bus wire 300 m
Where sensor and ‘eBUS’ cables run in parallel with
230 V cables over a length of 10 m, they must be separated by at least 25 mm.
2
230 V connection leads must be 1.5 mm
using the cable clamps supplied.
Do not use free terminals on the devices as support terminals for other wiring.
The unit must be installed in a dry room.
and secured

Note!
The VR 65 is designed to control one 3-port
valve or two 2-port valves. Systems requiring
more zone valves or a combination of 3-port
and 2-port valves are not possible.
Note!
The VR 65 requires a 230 V supply. The
ecoTEC boiler also requires a 230 V supply. The
eBUS wiring between the two will not provide
230 V from one device to the other!
