I installed a Zooz Zen22 dimmer into my previous 3 way circuit and cannot get it to work correctly. I have the following wiring setup (line and load in separate boxes).
The Zooz indicates to bring a load wire into the line box, but I am wondering why I cannot use the wiring that is already there. I am using a dumb switch as the 2nd switch. Installing a load wire in the line box would be very hard, messy, and seems unnecessary with all the wires in the box now.
Here is what I have tried.
I first tried to install this in the load box (preferred location). I connected the wires as follows:
Neutral — Neutral on Zooz
Load — Load on Zooz
Red (traveler) — Traveler on Zooz
Black (from traveler 3 wire romex) — Line on Zooz
The dummy had the red traveler and black traveler connected across from each other on the dummy switch, and the line wire connected to the other post on the switch. Neutrals in the line box were connected together with a wire nut.
This didn’t work right. So I tried switching the load and black traveler wire on the Zooz and it worked sort of, but if I turned on the dummy switch, the Zooz lost power. Leaving the dummy switch off, the system worked, but the dummy switches LED was dimmed when the Zooz was off.
So, thinking the problem was that I did not have constant line power to the Zooz, I switched it to the line box. I connected the wiring as follows:
Neutral — Neutral on Zooz
Line — Line on Zooz
Red (traveler) — Traveler on Zooz
Black (from traveler 3 wire romex) — Load on Zooz
This also worked sort of, but if I turned on the dummy switch, the Zooz lost power. Leaving the dummy switch off, the system worked, but the dummy switches LED was dimmed when the Zooz was off.
Is there a way for this to work? It would be best if I could use the load box and not the line box, but I will take what I can get. Anyone have any idea?
Thanks for reading this,
