Cause Remedy
The ON/OFF switch is switched off. Switch the ON/OFF switch ON.
The solar control unit MCB has respon-
ded (mains voltage is present, display is
not illuminated).
Inform your local heating contractor.
Collector limit temperature or set cylinder
temperature has been reached.
Wait until the relevant temperature has
fallen below its respective limit.
The solar control unit is in "Manual
mode".
Select "Auto" as follows:
1. Press .
2. Press until "Manual mode" is dis-
played.
3. Press OK to confirm.
4. Press until "Relay 1" etc. is dis-
played.
5. Press OK to confirm.
6. Press the / keys for "Auto".
7. Press OK to confirm.
8. Press until "Main menu" is dis-
played.
There is no DHW available
Cause Remedy
The solar control unit is faulty. Inform your local heating contractor.
Collector temperature is too high; safety
shutdown by the solar control unit.
Wait until the collector temperature has
dropped.
The set cylinder temperature (set DHW
temperature) has been set too low.
Inform your local heating contractor.
The solar circuit pump is faulty. Inform your local heating contractor.
The DHW cylinder is not being reheated:
The operating and time program is incor-
rectly set at the boiler control unit.
Enable DHW heating.

Cause Remedy
Power failure The solar control unit automatically re-
turns to operation once the power supply
has been restored.
The power distribution MCB (main do-
mestic MCB) has responded (no mains
voltage is present).
Check the MCB and inform your heating
contractor if necessary.
The display illumination flashes
Cause Remedy
Solar thermal system fault. Call up the fault (see following chapter)
and contact your local heating contractor
if necessary.
Calling up faults
If any faults have occurred in your solar
thermal system, the display illumination
flashes and "Fault" appears on the
standard display.

DHW cylinder (if installed)
Standards DIN 1988-8 and EN 806 spec-
ify that maintenance and cleaning should
be carried out no later than 2 years after
commissioning and as required there-
after.
Only a qualified heating contractor
should clean the inside of a DHW cylin-
der and the DHW connections.
If any water treatment equipment (e.g. a
sluice or injection system) is installed in
the cold water supply of the DHW cylin-
der, ensure this is refilled in good time.
In this connection, observe the manufac-
turer's instructions.
In addition for Vitocell 100:
We recommend that the correct function
of the sacrificial anode is checked annu-
ally by your heating contractor.
The function of the sacrificial anode can
be checked without interrupting the sys-
tem operation. The heating contractor
will check the earth current with an
anode tester.
Safety valve (DHW cylinder)
The function of the safety valve must be
checked every six months by the user or
a contractor through venting (see valve
manufacturer's instructions). The valve
seat may become contaminated.
Water may drip from the safety valve
during a heat-up process. The outlet is
open to the atmosphere and must not be
closed off.
Potable water filter (if installed)
To maintain high hygienic standards,
proceed as follows:
■ Replace filter element on non-back
flushing filters every six months (visual
inspection every two months).
■ On back flushing filters, back flush
every two months.

If there is damage to the connecting
cables or lines of the appliance or exter-
nally installed accessories, these must
be replaced with special cables or lines.
Only use Viessmann cables / lines as
replacement. For this, notify your quali-
fied contractor.
