Troubleshooting 3-Way or Multi-Switch Setup (Non-Neutral + Aux Switch) | Dimmer - Black Series (Gen 2) | LZW31

Troubleshooting 3-Way or Multi-Switch Setup (Non-Neutral + Aux Switch) | Dimmer - Black Series (Gen 2) | LZW31

Prerequisites

This is for if your switch is wired without a Neutral Wire and with an Auxiliary (Add-On) switch.
  1. Inovelli Model #'s: LZW31 (Black Series) or LZW31-SN (Red Series)
    1. This article does not relate to our Gen 1 dimmer models (NZW31, NZW31-S, NZW31-T)
  2. AC Power Type:  Neutral Installation 
  3. Switch Type (3-Way, 4-Way):  Auxiliary Switch (GE or HomeSeer)  
    1. Please do not use a dimmer dumb switch or an illuminated dumb switch 


Problem: Aux Switch Does Not Work

The Inovelli switch functions just fine (ie: dims up and down, turns on and off) but the auxiliary switch does not work at all, even with correct wiring.

Root Cause  

Switch has a factory default setting to work wired in a neutral wire setting as a single-pole setup and needs to be changed to work in a non-neutral setting with an auxiliary switch.

Solution

The switch needs to be programmed manually to work in a non-neutral setting with an aux switch. This can be done via the hub/gateway or manually via the switch itself. To do this via the switch itself, please follow these directions:  

Change to Non-Neutral 
  1. Hold down on the config button for 10 seconds until the LED bar turns Yellow 
  2. Press the config button 12x (LED bar should blink Yellow 1x slow and 2x fast) 
  3. Press DOWN on the paddle 1x 
  4. Hold down on the config button for 10 seconds until the LED bar turns Yellow -- let go 
  5. The LED bar should blink Cyan to save 
Change to Aux Switch 
  1. Hold down on the config button for 10 seconds until the LED bar turns Yellow 
  2. Press the config button 13x (LED bar should blink Yellow 1x slow and 3x fast) 
  3. Press UP on the paddle 1x and the LED bar should blink Purple 1x 
  4. Hold down on the config button for 10 seconds until the LED bar turns Yellow -- let go 
  5. The LED bar should blink Cyan to save 


NOTE: Please ensure your wiring is correct by checking the Wiring Guide , and the wires are securely fastened. Once both are verified and your switch still isn't working, please reach out to us .  


Programming Instructions (via Parameters)

The switch can also be programmed via a parameter change. Please ensure your hub / gateway supports parameter editing. 

From within your UI, please change the following parameters:
  1. Parameter 21 = Set Value to 0 (# of Bytes = 1)
  2. Parameter 22 = Set Value to 2 (# of Bytes = 1)
If your switch still isn't working properly, please ensure your wiring is correct by checking the Wiring Guide, and the wires are securely fastened. Once both are verified and your switch still isn't working, please reach out to us
