K8075 Stromsparer

Hi,
Does anyone know how to activate 8 hours - the jumper is mounted
thanks
max

A short press turns on the 4h timer, press again for 8h timer (led will flash slow instead of fast).

Thanks,
now, pressing twice, I have 8h, but there is no led flashing at all, no slow, no fast??? What can I do?

Has the led ever worked?
Has it been reversed? Check wiring.
Did you mount LD1 and the included pushbutton? (this does not work, if you use the pushbutton, remove LD1)?

The LED is working, but is no flashing at all - no fast, no slow…
I do not use LD1, I only use the pushbotton!
What can i Do?
Kind Regards
Max

Check your assembly, possibly there is a problem with R8, R10 or T1.

I have renewed several solder points around T1, now it works as it should.
Thanks
