Full Guide to Zooz Smart Switches

You're looking at all of these model numbers and are probably wondering: OK, they all look almost the same and seem to do the same thing, so which one do I choose for my project? We put together a comprehensive guide to navigate our growing line of light switches. We hope you find it helpful!

  Before you purchase:  

  • Please remember that our 3-way and 4-way diagrams for all switch models included in the manual and published in our support portal refer to the most common installations using a Zooz switch with a simple mechanical on/off switch. Please do NOT use these diagrams to connect Zooz switches with other Zooz switches (in the so called virtual 3-way/4-way set-up), nor with the ZAC99 momentary switches. NEVER connect Zooz switch to regular ("dumb") dimmers! Get in touch with us for custom instructions if you'd like to wire our switches in one of the special configurations.
  • Neutral wire is always required in at least one of the switch boxes for a Zooz wall switch to work correctly. If you're not sure if you have a neutral present, ask our support team. If you don't have a neutral available for your installation, you can always use the ZEN51 Dry Contact Relay mounted by the light fixture where you can find a neutral connection.
  • Some scenarios may require additional programming changes, like adjusting the 3-way switch type setting when using the ZAC99 momentary switch or disabling physical control not to cut power to smart bulbs when using our switches as remote controls. Make sure your Z-Wave hub gives you access to these settings before making your final decision. Not sure how to check this? Just ask!
  • Don't use our light switches with CFL ballast tube lights. If you replaced them with LEDs, please make sure the new bulbs replaced the ballast as well and connected directly to the fixture rather than using the old ballast.
  • Don't use our light switches with switched receptacles. You can safely use the relay part of our Double Switch (ZEN30) to control a 15 A switched receptacle.
  • Check the total (actual) power rating of your bulbs and compare it against the specifications of the switch / dimmer you're considering before making a final decision.

 

Take a look at the below scenarios for on/off and dimmer switches and see if you can find your perfect fit. If your use case isn't included or you have any questions about the guide, please let us know and we'll be happy to help!

Always follow the wiring instructions included in the manual with your switch or dimmer. Different models may wire differently in multi-control set-ups and it's easy to damage your device if it's not wired correctly on the first try. Need help? We provide custom wiring instructions for all of our devices, just get in touch!
