16.1 Malfunctions with error messages
If the controller detects a mal-
function, the red light flashes and the
warning symbol also appears in the
display. If the error is no longer
present, the warning symbol changes
to an info symbol and the red light no
longer flashes.
To obtain more detailed information
on the error, press the key under the
warning or info symbol.
Possible error messages:
Sensor x defective ——————>
Collector alarm
———————>
Night circulation ———————>

Notes for the specialist:
Means that either the sensor, the
sensor input at the controller or the
connecting cable is/was defective.
(Resistance table on page 5)
Means that the collector has fallen/
fell below the temperature set under
menu 6.3.1.
Means that the solar pump is/was in
operation between 23:00 and 04:00.
(Exception see 11.4)
Means that the controller was
restarted, for example due to a po-
