Leviton Countdown Timer Switch DT130-1LW
The Leviton DT130-1LW replaces a standard wall switch with four preset timers (5, 10, 15, and 30 minutes) to automate bathroom fans or small motors and related lighting. After you press a preset, the circuit automatically turns off when the timer ends, helping maintain humidity control and reduce unnecessary run-time. The unit supports LED, CFL, incandescent, and fluorescent loads up to 15A and up to half a horsepower for fans, making it a versatile option for many bathroom setups.
Installation is designed for shallow wall boxes, and the device uses a Green Flex Sleeve wiring method to ground when no neutral is available. If a neutral is present, you can configure the wiring accordingly by removing the sleeve. A ground connection is required for safe operation.

The unit is UL listed and requires a neutral wire for stable operation with modern lighting and fan loads, ensuring reliable performance in typical home bathrooms.
If a neutral exists in the wall box, wiring follows standard practice: connect the line to the feed, the load to the fixture, and the neutral to the neutral terminal as required. The device is built for straightforward installation and dependable performance on common bathroom circuits.

It features seven timer options, including 1, 5, 10, 15, 20, and 30 minutes, enabling precise control of a vent or light after a shower. The timer replaces a standard in-wall switch and requires a neutral wire for operation, ensuring compatibility with common bathroom loads.

Buying Guide
Key purchase considerations
- Wiring type: Decide between neutral-required and no-neutral options. No-neutral models (like some Leviton and BN-LINK variants) can simplify retrofits in older homes, but neutral-required units (like Enerlites and TG) offer more stable operation with modern fixtures.
- Preset range and repeatability: Look for the number and granularity of presets (1–30 minutes, 5–60 minutes, etc.). Some models offer manual override or repeat features for daily routines.
- Load compatibility: Ensure the timer supports your loads (LEDs, CFLs, incandescent, and/or fans) and the motor in your bathroom exhaust without tripping or failing to switch off.
- Installation and compatibility: Check wall box depth, plate style (toggle, decorator, or screwless), and whether the unit supports single-pole or multi-location setups.
- Certification and reliability: UL listing or equivalent standards indicate safety and reliability in humid bathroom environments.
Comparisons by use case
- Best no-neutral option: Leviton DT130-1LW for easier retrofits where a neutral wire is unavailable and ground is required.
- Best for strict 1–30 minute control: Enerlites 1-30 Min for precise, short cycles with clear neutral requirements.
- Best budget-friendly versatility: BN-LINK Countdown Digital Wall Timer for a wide range of presets and included wall plate.
- Best multi-location or premium install: Lutron Maestro for coordinated control and refined aesthetics in multi-gang setups.
- Best general purpose: TG 30-Min Countdown for straightforward installation with broad compatibility and a screwless plate.
Installation tips
- Turn off power at the breaker before removal of the existing switch and wiring of the timer.
- Match line (hot) and load connections as labeled on the timer and secure neutrals if required by the model.
- Ground the device where a ground wire is available; if a dedicated ground is not present, choose a model that uses a grounding sleeve or consult a professional.
- Secure the wall plate and ensure the device fits within the wall box without forcing the cover plate.
- Test the timer after installation by cycling through presets and confirming the load turns off when the timer expires.
These timers provide energy savings and improved humidity control in bathrooms by ensuring fans and lights do not stay on longer than needed. When selecting a model, consider wiring availability, desired preset ranges, load types, and whether you prefer a premium brand with multi-location capabilities or a straightforward single-pole switch for quick retrofits.
