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.

back to solar mode.
The immersion heater can be activated
to heat the DHW cylinder in the following
operating modes:
■ Timed heating
■ Heating with automatic mode
■ Heating to constant DHW temperature
Timed heating
You specify when the DHW cylinder is to
be heated with the immersion heater.
Two phases are set at the factory:

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
set DHW temperature is reached, the
immersion heater is switched off.

Cause Remedy
■ Insufficient insolation
■ Faulty immersion heater
■ Vacuum tube collector dirty or shaded
■ Faulty vacuum tubes
■ Faulty thermal insulation on the con-
necting lines
■ Not enough heat transfer medium in the
solar thermal system
■ Switch ON the immersion heater.
■ Clean the vacuum tube collector.
■ Have your contractor replace the faulty
vacuum tubes or thermal insulation and
top up the heat transfer medium.
Leak in the solar thermal system
Cause Remedy
Leaks in the connections or on the DHW
cylinder
Remove the plug with integral residual
current device from the socket. Have the
leak repaired by your contractor.
Water is constantly escaping from the safety valve
Cause Remedy
Overpressure in the pipework Notify your contractor.
Button B on the plug pops up (see page 13 13)
Cause Remedy
Faulty equipotential bonding Notify your contractor.
E1 is shown in the display
Cause Remedy
Faulty temperature sensor Notify your contractor.
What to do if...
DHW too cold
5516 345 GB

12
Cause Remedy
Faulty immersion heater. The heating wa-
ter temperature has risen to 90 °C.
Danger
DHW with temperatures in excess
of 50 °C can cause scalding.
At the DHW draw-off point ensure
that it is possible to mix in cold wa-
ter. If there are separate draw-off
points for the DHW and cold wa-
ter, always open the cold water tap
first.
Notify your contractor.

Viessmann solar collectors are tested for
impact resistance, for example against
hailstones, to EN 12975-2.
Nevertheless we recommend that the
user insures against extreme weather
conditions and includes the collectors on
their buildings insurance. Damage due
to these conditions is excluded from our
warranty.
Care, inspection and maintenance
■ Regularly check the thermal insulation
of the pipework.
■ Have leaking pipes and leaks in the
solar thermal system repaired imme-
diately.
■ We recommend regular checking of
the heat transfer medium (frost protec-
tion level and pH value).
■ Keep collectors free of dirt and snow.
Increased contamination lowers the
efficiency of the solar thermal system.
■ Have your solar thermal system serv-
iced regularly to ensure trouble-free,
energy-conscious and environmen-
tally responsible operation. For this, it
is recommended that you take out an
inspection and maintenance contract
with your local contractor.
■ Regularly check the plug with integral
residual current device.
A power cable connects this plug to
the DHW cylinder.

ual current device
