– Third-party boiler, non-eBUS-compatible
– Wiring via standard cabling box
– Solar circuit control via VRS560/2 solar controller
– Primary heating circuit control via VRS560/2 solar cont-
roller
– Room heating control via programmable timer and room
thermostat
– S or Y plan hydraulics
> Next to the solar cylinder, install a standard cabling box.
> Dismantle the cover for the standard cabling box.
> Dismantle the cover of the cylinder thermostat (13¬fig.
6.11).
> Insert a VR10 temperature sensor into the cylinder dry
pocket for SP2 (6¬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 (3¬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
terminal 230V~, connection L to terminal EP, connec-
tion 2.
Connect the VRS 560/2 and the cylinder thermostat
using a 2-core cable (phase conductor and protective
earth):
> Connect the connection 1 of the terminal EP of the VRS
560/2 with the terminal 1 (3¬fig. 6.12) 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.
