instructions
The controller must be installed by a qualified engineer,
who is responsible for adhering to the existing stand-
ards and regulations. We accept no liability for any dam-
age caused by failure to observe these instructions.
e
Danger!
Risk of fatal electric shock from touching live
connections.
Before working on the unit, switch off the
power supply and secure against restart. Only
remove the controller from the wall installation
or it pull out of the plinth once the power sup-
ply has been switched off.
3.2 Regulations
All wiring must be in accordance with Building Regula-
tions Part P and BS 7671 (IEE Wiring Regulations), and
must be carried out by a suitably qualified person.
Use standard wires for wiring.
Minimum cross-section of wires:
– Power supply 230 V
(pump connection cable):
1.5 mm
2
– Extra-low voltage lines
(sensor
wires):
0.75
mm
2
Connections with 230 V and sensor wires must be laid
separately if longer than 10 m.
230 V connection leads must be supplied in 1.5 mm
2
and
fastened to the wall installation using the accompanying
cable clamps.
Do not use free terminals on the appliances as support
terminals for other wiring.
The controller must be installed in a dry room.
H
Danger!
Danger of scalding due to hot water!
The temperature of the solar hot water storage
tank may sometimes be considerably higher
than 60 °C (due to the solar heating, but also
the anti-legionella function, if activated).
Have your expert technician install a mixer
valve with cold water supply without fail.
Have the mixer valve adjusted by your expert
technician.

4.2
Assembly of VR 10 standard sensor
The VR 10 standard sensor is designed so that it can be
used as an immersion sensor or surface mount sensor.
When used as a surface mount sensor, the sensor is se-
cured to the forward flow pipe or the return pipe using
the supplied tension band. In order to guarantee good
heat transfer, the sensor is flat on one side. We also rec-
ommend that the pipe with the sensor is insulated, in
order to enable the best possible measuring of tempera-
ture.

4.3 Accessories
The following accessories are necessary in order to con-
nect a second collector field or an additional solar cylin-
der to the controller, and to enable measurement of the
solar yield.
4.3.1
VR 10 standard sensor
The use of additional standard sensors is necessary if
you want to connect a second solar cylinder to the con-
troller.
4.3.2 VR 11 collector sensor
If a second collector field is connected, it is necessary to
install a second collector sensor from the Vaillant acces-
sory range.
