Take the WS15Z-1 in-wall switch and wire it in place of a wall switch, just the way it is shown in the diagram above.
Then wire the WS15Z-1 to the same line (or neutral) that is wired to the load being controlled. This should not be wired to any other neutral.
In case there are many neutrals in one box then use a circuit to separate the neutrals.
Adding to a network:
Add this switch to your Wireless Controller.
For that you would have to keep your Controller in Discovery or Add Mode.
Then tap the switch once for Network Wide Inclusion.
If you tap the switch twice then it is for Standard Inclusion.
As soon as you get an indication that the device was added to the network the LED of the switch would stop blinking.
Now, you will find the device in the list of Switches as a switch.
- In case the addition to the controller has failed then repeat the above steps once again.
