1 VRS560/2 or VR68/2
2 Terminal strip for series circuit to solar pump via TCO solar
circuit
3 Solar pump
4 Solar circuit thermal cut-out (TCO)
Connection wiring diagrams 1, 2, 3, 4, and 6:
> Next to the cylinder, install the VRS 560/2 solar control-
ler (1).
Connection wiring diagram 5:
> Next to the cylinder, install the VR68/2 solar module (1).
> Dismantle the cover of the VRS 560/2 solar controller or
the VR68/2 solar module.
> Dismantle the cover of the solar circuit thermal
cut-out(4).
> Connect the solar pump (3) in series with the provided
solar circuit thermal cut-out. To do so, use a protected
terminal strip (2) and 3-core cable provided by the cus-
tomer.
The solar pump and solar circuit thermal cut-out must
be earthed using a protective earth.
> You must carry out a protective earth test.
Connection wiring diagrams 1, 2, 3, 4, and 6
(VRS560/2):
> Connect the terminal strip with the terminal Kol1-P of
the VRS560/2(1).
Connection wiring diagram 5 (VR68/2):
> Connect the terminal strip with the terminal Kol1-P of
the VR68/2(1).

1 Solar yield temperature sensor
2 Solar return
> Mount the solar yield temperature sensor (1) on the
return line (2) of the solar circuit.
Connection wiring diagrams 1, 2, 3, 4, and 6 (VRS560/2):
> Connect the solar yield temperature sensor to the yield
("Ertrag") terminal of the VRS560/2 solar controller.
Connection wiring diagram 5 (VR68/2):
> Connect the solar yield temperature sensor to the yield
("Ertrag") terminal of the VR68/2 solar module.
