5-Way Diagrams for ZEN73, ZEN74, ZEN76 and ZEN77 Switches

You can wire your Zooz S2 switches in a 5-way as long as one of the boxes has power and neutral coming in directly from the breaker. The diagrams below can be used for the ZEN73, ZEN74, ZEN76, and ZEN77 models only. There's always only one correct option to wire your smart switch so please make sure you can match your set-up to the appropriate diagram before attempting the installation.

How can you identify power and neutral in your wiring? The easiest way to find out is to look for a black wire bundle and white wire bundle in the back of your multi-gang box. If you're dealing with single boxes only, you'll need to measure voltage on the black leads coming into each box in a 14-2 romex. Still not sure what you're looking for? Send us a few pics and we'll help you out!

We've created 5-way diagrams for the most common scenarios. But there are many different ways to wire multi-point control installations and if you're not able to match yours with the below "before" drawing, please don't experiment and reach out to us first for custom instructions.

Here are some things to note before you proceed with the installation:

A 5-way is what we call 4-point control so 4 different switches controlling the same set of lights.
These instructions can only be used with ZEN73, ZEN74, ZEN76, and ZEN77 models. If you have a ZEN71, ZEN72, or a ZEN32 switch, please click here for the 5-way wiring diagram.
You have to install the Zooz switch in the box with direct connection to power line and neutral.
Always use simple on/off 3-way and 4-way switches when connecting them to Zooz switches. No dimmers or electronic switches with a LED indicator may be wired to Zooz switches or dimmers.
There are many different types of 3-way and 4-way switches, some will have common terminals on top of the switch, some on the bottom. Always locate the common terminals first and adjust the orientation of the wires accordingly. Don't follow the diagrams blindly.
The colors of your wires may not match the ones in our diagrams so please make sure you've identified all wires correctly based on their source, not color only.
IMPORTANT: Once you connect your switches, please secure them in the box, making sure any bare wires and screws are isolated with electrical tape. After the switches are settled back in the box and the wall plate is re-installed, you can turn the power on and test the switches for on/off operation.
The diagrams show all connections but ground (it was excluded to simplify the illustration). Make sure all ground wires are connected to all switches respectively.

Once you're 100% sure you've identified all wires, please make sure power is off and wire the Zooz switch according to the diagrams below:

OPTION 1 with load and line in the same box (this is the less common scenario):

In this scenario, one of the wires from the 14-3 romex that carries the traveler will be used to carry power or load (connection to the light) to common on the 3-way switch in the last box. In our diagram, in the "before" option, we show the most common situation in our experience where power is carried through the second and third boxes to the fourth using one of the wires traveling from box 1 to box 4. Since Zooz switches need direct connection to power, in the "after" diagram we show that whatever connection was carried over from box 1 to box 4 in the "before" scenario, we always need to connect the Zooz switch to the direct power source in box 1 and the connection traveling from box 1 to common on the switch in box 4 is always going to be the connection to the light (load).

BOX 1 (the box with power where your Zooz switch goes - this is the only box the Zooz switch can be installed in for these models):
1. Disconnect the black wire coming from your 14-3 romex (make sure this is the wire that connects to common on the regular 3-way switch in box 3) and connect it under a wire nut with the black wire from the 14-2 romex going to the lights.
2. Run a jumper wire (a piece of 14 AWG wire) from the black power source bundle to the Line terminal on the Zooz switch (or if there's a single wire with power in the box, connect that single wire to the Line terminal).
3. Connect the red wire from the 14-3 romex to the Traveler terminal on the Zooz switch.
4. Connect the white wire from the 14-3 romex to the Load terminal on the Zooz switch.
5. Run a jumper wire (included in the packaging) from the white wire bundle to the Neutral terminal on the Zooz switch.

6. Connect ground to ground.

Leave the switches in the other boxes wired as is. No changes needed provided that they're wired as shown in our diagram: white and red travelers on the 4-way switches in box 2 and box 3, black wires tied together in box 2 and box 3; black wire to common, red and white wires to traveler terminals on the 3-way switch in box 4. Note that depending on the type of your 4-way and 3-way switches, the location of traveler and common screws on the switch may be different so don't follow the orientation of the wires or their color blindly, always verify the actual role of each wire first.

OPTION 2 with load and line in separate boxes (this is the most common scenario):

BOX 1 (the box with power where your Zooz switch goes - this is the only box the Zooz switch can be installed in for these models):
1. Connect the black wire coming from your 14-3 romex to the Load terminal on the Zooz switch (make sure that wire connects to one of the traveler terminals on the regular switch in box 2).
2. Connect the black wire coming from the black power source bundle to the Line terminal on the Zooz switch (or if there's a single wire with power in the box, connect that single wire to the Line terminal).
3. Connect the red wire from the 14-3 romex to the Traveler terminal on the Zooz switch (make sure that wire connects to one of the traveler terminals on the regular switch in box 2).
4. Run a jumper wire (included in the packaging) from the white wire bundle to the Neutral terminal on the Zooz switch.
5. Connect ground to ground.

Leave the switches in the other boxes wired as it is. No changes needed provided that they are wired as shown in the diagram: black and red travelers on the 4-way switches in box 2 and box 3, white wires tied together in box 2 and box 3; black wire from the 14-2 romex going to the light connected to common, red and black wires from the 14-3 traveler romex connected to traveler terminals on the 3-way switch in box 4.
