Hi
First unplug the digital power bar from S1-4
Now plug in the doser
Assuming you have one digital power bar, go to socket outlet function and then click on the icon for programming power bars and dosers
You want to select doser
Now program from 7 upwards depending on what doser you have so for a 3 doser it will number from 7-9
After going through the set up and saving the settings, unplug the doser from S1-4 and plug back in the power bar
The doser now daisy chains off the digital power bar second western socket
