>
Next to the solar cylinder, install the VR 61/2 mixer
module.
>
Install a VRC weather compensator next to the solar
cylinder.
>
Dismantle the covers of the VR 61/2 and the VRC cont-
roller.
>

SP 1
of the VR 68/2.
>
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 VR 68/2.
>
Mount the casing (

¬
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 VR 61/2.
>
Install the eBUS connection from the gas-fired wall-hung
boiler to the VR 68/2.
>
Install the eBUS connection from the gas-fired wall-hung
boiler to the VRC controller.
>
Optional: Install the eBUS connection from the gas-fired
wall-hung boiler to the VR 81.
>
Connect the zone valves for the heating circuit and hot
water circuit in accordance with connection diagram 5 (S
plan hydraulics).
>
Connect the gas-fired wall-hung boiler, VR 61/2, and
VR 68/2 to the power mains.
>
Mount the covers of the VR 61/2, the VR 68/2 and the
VRC controller.
>
Adjust the Vaillant dual-channel eBUS controller in
accordance with its operating and installation instruc-
tions.
>
