The first thing to try is excluding the switch from your Z-Wave system; exclusion is like a soft reset: 

This is product is discontinued and replaced with ZEN71.

What does that mean?

A device doesn't need to be included to be able to excluded. Here's how to do it: 

1. Bring your Z-Wave hub as close to the switch as possible
2. Put your Z-Wave controller into exclusion mode
3. Tap the lower paddle of the switch 3 times very quickly to finalize the exclusion process
4. The device will disappear from your controller's device list

If that didn't work, here are some troubleshoots we find helpful: 

• Simply try the exclusion process again! Who knows, maybe the exclusion commands from the first run weren't registered correctly. 
• If possible, try bringing the hub within direct range of the switch if you were at a large distance the first time. If you have a hand-held secondary controller, this would be the time to bring it out!
• Try the exclusion process again, only this time instead of tapping 3 times, tap the paddle 6 or 7 times at least as quickly as possible. This can help make sure the commands go through.
• For those of you referring to the older version of the manual, there's a mistake in the inclusion section. You shouldn't try including the device by tapping the paddle in an up-down-up motion; this is incorrect. Instead make sure to perform the action as shown in step 3 above. The online and print documentation have been corrected as of February 2018, but this tip is for users who happen to have the older version of the manual.
• And if you find that your switch is connected but it's not responded to remote commands, check out these tips for troubleshooting connectivity. 

After exclusion is completed, give inclusion another try to see if that helped the issue.
