Before installing, make sure the load does not exceed 960W for incandescent lights or 1800W (15A) for resistive load. Check your wiring first to confirm that you have all the following wires present in your gang box: load (most often black), line (most often black), neutral (most often white), and ground (most often green).

If you are not comfortable identifying the wiring and completing the installation, please consult a licensed electrician.

Here are some helpful installation tips:

    • Make sure the gang box you are about to install the switch at features a neutral wire - you will not be able to connect the ZEN21 switch properly without a neutral wire.
    • Unlike your regular electric switches, Z-Wave switches require particular wires to be connected exactly as indicated - line and load wires cannot be swapped as it often happens to the most experienced electricians.

How to include the Z-Wave Plus On / Off switch to your smart home network?
1. Bring your Z-Wave gateway hub or controller as close to the switch as possible
2. Put your Z-Wave controller in inclusion/pairing mode
3. Tap the switch on and off quickly 3 times to finalize the inclusion process
4. A new on/off switch should appear on your controller's device list

 NOTE:  DO NOT wire this switch in a 3-way setting with regular electrical switches. If you are looking to control one light with 2 or 3 switches, please contact us for installation instructions.
