With our new approach to 3-way, you can now wire your ZEN52 Double Relay in several scenarios for different multi-point control installations. Please make sure that you're able to match your set-up with the appropriate diagram before the installation.
Follow the notes for each diagram and never attempt to wire the relay on your own without expert electrical knowledge. There is no room for error with 120 V installations and it is recommended that a licensed electrician performs the installation.
If you'd like us to create custom instructions for you, just send us a few images from each switch box and we'll help! Make sure to show us a full picture of the box so we're able to trace each wire to its source. Always include your order number and images of the original fully working installation when reaching out to us for guidance.
PLEASE READ before you proceed with the installation:
- A 3-way is what we call 2-point control so 2 different switches controlling the same set of lights.
- These instructions can only be used with the ZEN52 Double Relay.
- You have to install the Zooz Double Relay in the box with direct connection to power line and neutral.
- Always use simple on/off 3-way switches when connecting them to the Zooz relay. No dimmers or electronic switches with a LED indicator may be wired to Zooz relays.
- There are many different types of 3-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.
- The diagrams show all connections but ground (it was excluded to simplify the illustration). Make sure all ground wires are connected to all wall switches respectively.
Once you're 100% sure you've identified the wires, please make sure power is off and wire the Zooz Double Relay according to the instructions below.
These diagrams illustrate the most common 3-way set-ups. But there are other creative wiring scenarios for 2 switch controls so if you're not able to match yours with the below drawings, please don't pick the closest option. Trial and error are not a good idea with high-voltage installations. Instead, reach out to us first for custom instructions.
OPTION 1: LOAD AND LINE ARE IN THE SAME BOX
For this scenario, install the ZEN52 in the box with direct connection to power (the box where line is coming directly from a breaker and not through one of the wires in your 14-3 traveler romex).
Do NOT change any advanced settings before testing the relay after you wire it. You're able to use 2 types of external switch settings (parameters 20 and 21) in this scenario: toggle switch (value 0) or toggle switch with fixed actions (value 2) if using regular 3-way on/off switches. Do NOT use the 3-way impulse control (value 3) for this scenario. Click here for the full setting list.
OPTION 2: LOAD AND LINE ARE IN SEPARATE BOXES
For this scenario, install the ZEN52 in the box with direct connection to load (the box where the light connection goes to common on the 3-way switch).
NOTE: You need to add the ZEN52 to your hub and change the external switch type settings (parameters 20 and 21 if both relays are wired according to this 3-way scenario) before testing this set-up once it's wired. Select the 3-way impulse control (value 3) for this kind of set-up. Click here for the full setting list.
