This manual is intended for persons with the following quali-
fications.
2.1.1 Authorised competent person
The installation, assembly and removal, start-up, mainten-
ance, repair and decommissioning of Vaillant products and
accessories must only be carried out by authorised compet-
ent persons.
Note
Each competent person is qualified for specific
activities on the basis of their training. They must
only work on units if they have the required quali-
fication.
When working on the units, the competent persons must
observe all applicable directives, standards, laws and other
regulations.
2.2 General safety information
2.2.1 Installation by skilled tradesmen only
The unit must be installed by a qualified, skilled tradesman,
who is responsible for compliance with the applicable re-
quirements, regulations and directives.
▶Read through these installation instructions carefully.
▶Carry out the activities that are described in these install-
ation instructions.
▶During the installation, observe the following safety in-
structions and regulations.
2.2.2 Risk of death from live connections
When working in the electronics box of the boiler, there is
a risk of death from electric shock. Continuous voltage is
present on the mains connection terminals, even if the main
switch is turned off.
▶Switch the main switch off before working on the electron-
ics box of the boiler.
▶Disconnect the boiler from the power mains by discon-
necting the mains plug or by de-energising the boiler via
a partition with a contact opening of at least 3 mm (e. g.
fuses or power switches).
▶Check that the boiler is de-energised.
▶Secure the power supply against being switched on
again.
▶Open the electronics box only when the boiler is discon-
nected from the power supply.
2.2.3 Material damage due to unsuitable
installation room
If you are installing the controller in a moist environment, the
electronics may be damaged by moisture.
▶The controller should only be installed in dry rooms.

6Installation instructions VRT 350 0020131957_01
2.2.4 Danger due to error functions
▶Ensure that the heating system is in a technically perfect
condition.
▶Ensure that no safety or monitoring devices have been
removed, bridged or disabled.
▶Immediately rectify any faults and damage that may affect
safety.
▶Install the controller in a location where it is not covered
by furniture, curtains, or other objects.
▶If thermostatic control is activated, advise the operator
that, in the room where the controller is mounted, all the
radiator valves must be fully open.
▶Do not use the unit's free terminals as supports for other
wiring.
▶At lengths of over 10 m, 230 V supply cables must be laid
separately from sensor or bus lines.
2.3 CE label
CE labelling shows that, based on the type over-
view, the appliances comply with the basic requirements of
the following directives:
–Electromagnetic compatibility directive (Council Directive
2004/108/EC)
–Low voltage directive (Council Directive 2006/95/EC)
2.4 Intended use
State-of-the-art
The controller is a state-of-the-art unit manufactured in ac-
cordance with recognised safety regulations.
Even so, in the event of inappropriate or non-intended use,
damage to the appliance and other property may arise.
The controller controls a heating installation with a Vaillant
heater with eBUS interface in a way that is room-controlled
and time-dependent.
The controller can control the hot water generation of a con-
nected domestic hot water cylinder.
Operation is permissible with the following components and
accessories:
–Domestic hot water cylinder (conventional)
–VR 66 Control Centre
Improper use
Any other use, or use beyond that specified, shall be con-
sidered improper use. Any direct commercial or industrial use
is also deemed to be improper. The manufacturer/supplier is
not liable for any resulting damage. The user alone bears the
risk.
Improper use of any kind is prohibited.
Other applicable documents
Intended use includes the following:

2. Mark the position on the wall. Take the eBUS line route
into account when doing so.
3. Drill two holes matching the positions of the mounting
holes (3).
–Diameter of mounting hole: 6 mm
4. Insert the eBUS line through one of the cable ducts (4).
5. Insert the wall plugs supplied.
6. Use the screws supplied to secure the wall-mounting
base.
7. Connect the eBUS line to the terminal block.

8. Carefully insert the controller in the wall mounting base.
Ensure that the pin header (5) on the wall-mounting
base fits into the controller connector provided.
9. Carefully press the controller into the wall-mounting
base until the locking tabs on the controller are heard
to latch into the sides of the wall-mounting base.
5 Electrical installation
When connecting the eBUS line, there is no need to pay at-
tention to the polarity. If the two connections are switched
around, communication is not affected.
If you want to use a VR 66, observe the installation instruc-
tions for the VR 66 Control Centre.
