Possible error messages:
Notes for the specialist:
Sensor x defective ---------------->
Means that either the sensor, the sensor input
at the controller or the connecting cable is/was
defective.
(Resistance table see B.1)
Collector alarm -------------------->
Means that the collector has fallen/fell below the
temperature set under menu 6.5
Night circulation ------------------->
Means that the solar pump is/was in operation
between 23:00 and 04:00. (Exception see 6.6)
Restart ------------------------------>
Means that the controller was restarted, for example
due to a power failure. Check the date&time!
Time&date ------------------------->
This message appears automatically after a
mains failure because the time&date have to be
checked, and reset if necessary.
If the controller detects a malfunction, 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.
