• Select the correct wiring scheme for the installation,
depending on the boiler and control components used,
as specified in Table 5.7.

Wiring of the control components
Wiring scheme 1
- eBUS-capable Vaillant boiler
- Wiring via VR 65
- Solar circuit control via VRS 560
- Solar circuit reheating control via VRS 560
- Heating circuit control via Vaillant eBUS compatible
controller
- Overview removal of the cylinder thermostat, see
Fig. 5.22 (if a Vaillant eBUS controller is used)
- Installation of two VR 10 temperature sensors in the
solar cylinder (see Fig. 5.23)
- Attachment of the solar gain sensor to the solar
circuit return (see Fig. 5.23)
- Connection of the solar pump to the solar control via
its own thermal cut out (see Fig. 5.24)
• Fit the Control Center V 65 next to the cylinder for
easy electrical connection.
Before the VR 10 temperature sensor can be installed,
the cylinder thermostat, the thermal cut out (TCO) and
the capillary tubes of the cylinder thermostat and ther-
mal cut out must first be removed.
