You must connect the solar pump to the solar
controller via the solar circuit thermal cut-out
(5) (¬ section 6.8). The thermostat switches the
solar pump off if the hot water temperature in
the cylinder exceeds 80 ºC. Set the maximum
cylinder temperature (MAXT 1)
to 75 °C (factory setting) on the auroMATIC
VRS 560 solar controller.

The cylinder is equipped with an additional electric
immersion heater (3) with a heating output of 3 kW. The

If you need to make a replacement, you must
use the correct electric immersion heater with a
thermal cut-out for overheating protection. The
seal of the electric immersion heater must also
always be replaced. Use only original replace-
ment parts from Vaillant Ltd.

You can set the hot water temperature by pointing the
arrow on the temperature controller (1) of the electric
immersion heater to a number between 1 and 5. The fol-
