LED lights flickering might be due to driver incompatibility between the bulb and dimmer.
The executive element in the ZEN72 Dimmer switches is TRIAC, a leading edge driver. If your LED bulbs call for a dimmer that uses a trailing edge driver, it could cause the lights in your installation to flicker.
If you'd prefer not to change the bulbs, you can try adding a bypass to the load.
Here is how to wire the bypass with your ZEN72 Dimmer:
- Turn the power off at the breaker before removing the switch from the box and/or handling any wires.
- Connect one wire from the bypass to the Load terminal on the ZEN72 - it will also be connected to the load wire going to the light. You can either create a small wire bundle as shown in the diagram below or connect both wires to the 2 holes in the Load terminal on the ZEN72 for a cleaner installation.
- Connect the other wire from the bypass to the Neutral bundle where you'll already have the neutral from the light, neutral from the power line, as well as the neutral jumper from the ZEN72 neutral terminal connected together.
- Follow the appropriate ZEN72 wiring diagram for all other connections to the dimmer.
- Once you connect your switch, secure it in the box, making sure any bare wires and screws are isolated with electrical tape. After the switch is settled back in the box and the wall plate is re-installed, you can turn the power on and test the dimmer again to see if the flickering issue has been resolved.
Another important details is to make sure your LED bulbs are labeled as dimmable. On/off LED bulbs are not compatible with dimmers and will not perform correctly.
Never use a Z-Wave dimmer with smart bulbs unless you disable paddle control on them first. Dimming smart bulbs from a wall dimmer may damage your equipment.
