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
electric immersion heater is located behind the top front
cladding. The electric immersion heater is designed for
use in unvented cylinders and has a thermostat with a
temperature controller (
1
) and a thermal cut-out (TCO)
with a reset button (
2
).
i
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.
Setting the hot water temperature
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-
lowing table contains the approximate hot water temper-
ature for each of the five settings.
