> Next to the solar cylinder, install the Vaillant Control Cen-
tre.
> Dismantle the cover of the Vaillant Control Centre.
> 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 bottom cylin-
der 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.
> Connect the terminal EP of the VRS560/2 with the ter-
minal CYL. of the Vaillant Control Centre.
i
The terminals NTC and CYL. of the Vaillant Con-
trol Centre may not be connected at the same
time.
> 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.
The electrical installation of the eBUS connection is
described in the installation instructions for the Vaillant
dual-channel eBUS controller.
> Install the eBUS connection from the gas-fired wall-hung
boiler to the Vaillant Control Centre.
> Install the eBUS connection from the gas-fired wall-hung
boiler to the Vaillant dual-channel eBUS controller.
> Connect the zone valves for the heating circuit and hot
water circuit in accordance with connection diagram 3 (S
plan hydraulics).
> Connect the gas-fired wall-hung boiler, Vaillant Control
Centre, and VRS 560/2 to the power mains.
> Mount the covers for the Vaillant Control Centre and the
VRS560/2.
> Adjust the Vaillant dual-channel eBUS controller and the
VRS 560/2 solar controller in accordance with their ope-
rating and installation instructions.
> 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).
