• Select the correct wiring scheme for the installation,
depending on the boiler and control components used,
as specified in Table 5.7.
h Note!
You must set the controller of the cylinder
thermostat (1) to maximum temperature if you
use one of the wiring schemes 2 or 4.

- Overview removal of the cylinder thermostat (see
Fig. 5.22)
- 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.
