The solar circuit has stopped because
the controller is conducting a priority
test. This test checks whether, instead
of the second-priority storage tank, the
first-priority storage tank could also be
loaded.
This test can take several minutes, as the
collector array must heat up sufficiently.
Solar circuit is running due to interval
test.
The collector's heat transfer fluid is be-
ing transported to the sensor.
The solar circuit is running in order
to protect the collector from icing up.
Despite the fact that the pump is
running, the temperature difference
between the collector and the external
heat exchanger is too great.
-> Volume flow is too low.
Despite the fact that the pump is
running, the temperature difference
between the external heat exchanger
and the storage tank is too great.
-> Volume flow is too low.
Gravity circulation is causing the collec-
tor to be heated at night.
Solar circuit shows "suspicious" cycle
behaviour.
The internal settings check
has identified conflicting settings, or
double allocation of sensors.
The internal plausibility check
has identified conflicting settings.
A sensor error has been detected.
Sensor cable is interrupted, incorrectly
connected, or the sensor is possibly
defective.

Check the solar circuit's hydraulics,
pump, valves, and shut-off devices.
If necessary, bleed the system, open
the shut-off devices, and flush out
blockages.
Check the loading circuit's hydraulics,
pump, valves, and shut-off devices.
If necessary, bleed the system, open
the shut-off devices, and flush out
blockages.
Check the gravity brake (non-return
valve) and the time set in the control-
ler.
Check the collector array's supply and
return pipes, and mount them cor-
rectly if applicable.
Check the function's time settings.
Double allocation of sensors is per-
mitted, and this is only intended as
information.
Look up the error code in the operat-
ing instructions (chapter 1) and
check/correct the entries.
Locate and check the corresponding
sensor(s) in the display menu.
Check connection and/or sensor ca-
ble. Possibly check sensor and sensor
cable using an ohmmeter.
