In-wall fluorescent dimmers use a separate low-voltage 0-10V or 1-10V control signal to adjust the output of a compatible dimmable ballast. Many also include a built-in relay for separate line-voltage on and off control, while the ballast and dimmer wiring must match the specified control method.

In-wall fluorescent dimmers in this category are designed for four-wire, 0-10V or 1-10V dimmable ballasts and support line-voltage applications listed for the device, such as 120V, 277V, or 240V. A neutral wire is required for the backlit buttons, and the control output can sink or source up to 100 mA, while the built-in relay provides separate line-voltage on and off control when needed.

Yes, these in-wall fluorescent dimmers can provide separate on and off control for line-voltage lighting loads through a built-in relay. This allows the device to manage the 0-10V dimming signal and line-voltage switching when the lighting setup calls for both.

In-wall fluorescent dimmers can connect with automated lighting and smart home systems through Zigbee, allowing programmed commands to adjust 0-10V or 1-10V dimmable fluorescent ballasts. Depending on the system, the dimmer can also provide separate on/off control, status feedback through programmable LEDs, and energy-use monitoring.
