Notes for the specialist:

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 re-
started, for example due to a power
failure. Check the date&time!
This display appears automatically
