Cause Remedy
The mains isolator is switched OFF. Switch ON the mains isolator.
The solar control unit MCB has respon-
ded (mains voltage is present, display
does not illuminate).
Contact your local heating contractor.
Collector limit temperature or set cylinder
temperature has been reached.
Wait until the respective temperature has
fallen below the relevant limit.
The solar control unit is in "manual
mode".
To select "Auto":
1. Press .
2. Press until "Manual mode" is dis-
played.
3. Press OK to confirm.
4. Press until "Relay 1" etc. is dis-

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. Contact your local heating contractor.
Collector temperature too high; safety
shutdown through the solar control unit.
Wait until the collector temperature has
fallen.
The set cylinder temperature is too low. Contact your local heating contractor.
Solar circuit pump faulty. Contact your local heating contractor.
The DHW cylinder is not reheated:
The operating and time program is incor-
rectly set at the boiler control unit.
Enable DHW heating.

Cause Remedy
Power failure. After power has been restored following
a failure, the solar control unit returns into
operation automatically.
The power distribution MCB (main
domestic MCB) has responded (mains
voltage is not present).
Check the MCB and contact your heating
contractor, if necessary.
The display illumination flashes
Cause Remedy
Solar thermal system fault. Scan the fault (see following chapter) and
contact your local heating contractor, if
necessary.
Scanning faults
If any faults have occurred in your solar
thermal system, the display illumination
flashes and "Fault" appears on the
standard display.

3. OK to confirm.
4. / for current causes of the fault
5. Make a note of the cause of the fault.
This enables the heating contractor to
be better prepared for the service call
and may save additional travelling
costs.
