When choosing function 5 (slow ON/OFF), is it possible to adjust the delay when going OFF and also the delay when going ON ?
I have the K8028 which is basically the same. I have managed this and it is possible - go to the learning mode (xxxo) and follow the instructions. Then try it again. if it still doesn’t work then perhaps you should try new modes - although it depends if the switch you are using is a momentary type or a toggle (ON/OFf)
