Tip when testing
If you want to test a function, e.g. the sun, you have to wait for the on and off delays.
By setting the controller to test mode all delays will be shortened by a factor of 60.
Important!
Do not forget to return to normal mode when finished.

Why do the solar protection go down when I press the Up button (or vice versa)
There is an error in the wiring (see section G+H+I+K).
n
The solar protection does not go sufficiently low when the sun shines.
Increase the down running time (see section D+L).
n
The blinds do not tilt enough when the sun shines.
Increase the tilt time (see section D+L).
n
I can’t move the solar protection manually
Check LCD to see if any blocking function is active (e.g. wind) (see section B+D).
n
There is sun but the solar protection is not down.
Is the control in automatic mode? (See section A+B).
Is the sun function enabled? (See section D+O).
Check LCD to see if any blocking function is active (e.g. Wind, Timer, Error or Get Heat) (see section B+D).
Is there sun on the sun sensor?
Perhaps your sun on threshold is set to high? Check present sun value in sensor status and
compare with your “On threshold” (see section B+D+M).
Is the sensor allocated correctly? (See section D+M+O).
n
There is no sun but the solar protection is down.
Is the control in automatic mode? (See section A+B).
Is the sun function enabled? (See section D+O).
Check LCD to see if any blocking function is active (e.g. Preserve Heat ,Timer) (see section B+D).
Is there sun on the sun sensor?
Perhaps your sun up threshold is set to low? Check present sun value in sensor status and
compare with your on threshold (see section B+D+M).
Is the sensor allocated correctly? (See section D+M+O).
n
The solar protection moves to often up and down during a partially cloudy day
Increase “sun off” and “sun on” delay (see section D+O).
n
It’s very windy but the solar protection is still out.
Is wind function enabled? (See section D+O).
Is wind sensor turning?
Is the wind sensor mounted in adequate position?
Perhaps your wind threshold is set to high? Check present wind value in sensor status and
compare with your threshold (see section B+D+M).
Is the sensor allocated correctly? (See section D+M+O).
n
Nothing seams to work as it used to do
Check if there is an error indicated on the LCD or in the error list (see section B+D+N).
