¬
fig. 6.11
).
>
Connect this lower cylinder sensor (SP 2) to the terminal
SP 2
of the VRS 560/2.
>
Insert a VR 10 temperature sensor into the cylinder dry
pocket for SP1 (

¬
fig. 6.11
).
>
Connect this upper cylinder sensor (SP 1) to the terminal
SP 1
of the VRS 560/2.
>
Mount the VR 11 collector sensor (Kol 1) in the provided
sensor sleeve on the collector array.
>
Connect the VR 11 collector sensor (Kol 1) to the terminal
Kol 1
of the VRS 560/2.
For S plan hydraulics:
>
Install standard S plan wiring between the boiler,
two port valves, terminal
C
of the cylinder thermostat,
and the standard cabling box.
For Y plan hydraulics:
>
Install standard Y plan wiring between the boiler, 3-way
zone valve, terminal
C
of the cylinder thermostat, and
the standard cabling box.
>
In the VRS 560/2 solar controller, install a bridge from

Connect the VRS 560/2 and the cylinder thermostat
using a 2-core cable (phase conductor and protective
earth):
>
Connect the connection

of the terminal
EP
of the VRS
560/2 with the terminal

) of the cylinder
thermostat.
>
Connect the protective earth connection of the VRS 560
with the protective earth terminal (
2
¬
fig. 6.12
) of the
cylinder thermostat.
Connect the standard cabling box with the thermal cut-
out (TCO) for the primary heating circuit using a 2-core
cable (phase conductor and protective earth):
>
Connect the standard cabling box with the terminal
C
(
5
¬
fig. 6.12
) of the primary heating circuit TCO.
>
Connect the protective earth connection of the standard
cabling box with the protective earth terminal (
4
¬
fig.
6.12
) of the primary heating circuit TCO.
>
Install a bridge between the protective earth terminal
(
2
¬ fig. 6.12
) of the cylinder thermostat and the protec-
tive earth terminal (
4
¬ fig. 6.12
) of the primary heating
circuit TCO.
>
Mount the cover for the cylinder thermostat.
>
Mount the casing (
5
¬ fig. 6.11
) on the cylinder and use
the cutouts in the casings for routing the cables.
>
Mount the front claddings of the casing.

>
Connect the boiler, VRS 560/2, and standard cabling box
to the power mains.
>
Mount the covers for the VRS 560/2 and the standard
cabling box.
>
Adjust the Vaillant VRS 560/2 solar controller in
accordance with its operating and installation instruc-
tions.
>
Set the maximum cylinder temperature (MAXT 1) to 75 °C
(factory setting) on the auroMATIC VRS 560/2 solar con-
troller (see operating instructions for the VRS 560/2).
i
The switching signal for the primary heating of
the hot water is forwarded to the S plan/Y plan
wiring via terminal
EP
of the VRS 560/2, the cyl-
inder thermostat, and the primary heating cir-
cuit TCO.
