Commissioning must be undertaken by
the system installer or a specialist
authorised by the installer.
Operating tips
!Please note
Excess temperatures can result
in damage to the solar thermal
system.
Therefore never switch off the
solar thermal system in summer,
e.g. during a holiday.
If necessary, cover the vacuum
tube collector.
Modifications to the existing installation,
e.g. to the safety equipment or the drain
lines must only be carried out by author-
ised contractors.
Danger
DHW with temperatures in
excess of 50 °C can cause scald-
ing.
At the DHW draw-off point,
ensure that it is possible to mix in
cold water. If there are separate
draw-off points for the DHW and
cold water, always open the cold
water tap first.
On the control unit display, read
off the DHW temperature (see
page 6).

Heating of the DHW cylinder
■ Vitosol 222-T can be operated all-year
round.
When there is sufficient insolation, the
DHW cylinder is heated purely by the
vacuum tube collector (solar mode).
If the desired DHW temperature can-
not be achieved with the vacuum tube
collector alone, the integral immersion
heater can be switched on.
Note
Constant operation of an immersion
heater results in high electricity con-
sumption.
■ Heating with the immersion heater can
be started manually (see page 8).
Time
■ The local time can be adjusted (see
page 8).
Power failure
■ The programmed data is retained for
72 hours.
In the event of a fault
■ The immersion heater is switched off,
the operating keys are locked. Notify
your contractor.
For fault displays, see page 11.

Heating to constant DHW temperature
In this operating mode, the DHW cylinder
is heated to the DHW set value. Once the
actual DHW temperature has dropped
by 5 °C, the immersion heater is
switched on again and the water is
heated to the set DHW temperature.
Press key K3 6 times.
The symbol appears in the display.
Heating with automatic mode
This operating mode is set at the factory
to 04:00 and 16:00 h.
The immersion heater starts to heat the
DHW cylinder at these times. When the
