Leviton DT160-1LW Countdown Timer Switch — 10/20/30/60 Min, No Neutral, 15A, White

Enhance control with the Leviton DT160-1LW Countdown Timer Switch

Upgrade your wall switches with a compact countdown timer that can simplify how you manage fans, lights, and other small loads. The DT160-1LW provides four preset durations—10, 20, 30, and 60 minutes—so you can run a bathroom exhaust fan, towel warmer, heat lamp, or attic vent for a targeted period without leaving circuits on longer than needed. When the timer reaches zero, the device automatically powers down, offering a convenient way to reduce unintended operation and help manage energy use.

What makes it smart

• Flexible wiring: no neutral is required in many installations, and the Green Flex Sleeve connects to ground; you can remove the sleeve if a neutral is present.
• DIY friendly: two black wires are interchangeable between line and load to help prevent miswiring during install.
• Compact depth: slim profile fits inside most standard wall boxes for a clean, unobtrusive install.
• Power handling: supports 600W LED/CFL, 1800W incandescent/halogen, 1200VA MLV/ELV/FL, and ½ HP / 9.8A fan or motor; 15A resistive ratings apply.
• Color and compatibility: pairs with Decora wallplates and offers color options via DTKIT to match décor.

In addition to the built‑in timer, the device adds a practical approach to energy awareness by helping you avoid leaving devices on unintentionally. The timer is designed to work with existing wiring, enabling a straightforward upgrade path without a full rewire.

Practical uses

• Ideal for bathroom exhaust fans to help control humidity after showers.
• Suitable for heat lamps, towel warmers, saunas, hot tubs, and attic fans to provide timed operation.
• Helpful for lighting and other small loads where a timed cycle can reduce glare or overuse.

The device is intended to support a range of residential loads, giving you flexibility to tailor applications to your space and routine. If a neutral wire exists in your wallbox, you can adapt the grounding approach accordingly. Always observe proper wiring practices and grounding requirements for safe operation.

How to install and configure

The DT160-1LW replaces a standard single-pole switch and works with your existing wiring. Its shallow depth helps with installation in tight wall boxes, and the line/load interchange helps minimize miswiring during setup. A ground connection is recommended for safety, and the sleeve can be adjusted if a neutral is available in the box.

Design, branding, and options

The countdown timer blends clean lines with the Decora aesthetic. The white finish pairs well with other Decora devices, and you can refresh the look with DTKIT faceplates in white, ivory, light almond, gray, black, and brown to match your interior style.

Notes

Do not use to control the only light source in an area. For best compatibility, pair with Decora wallplates and review your loads and wiring conditions before installation.
