GE SunSmart Digital In-Wall Timer
GE’s SunSmart timer offers automatic adjustments for daylight changes through the year, aligning ON/OFF times with seasonal sunrise and sunset. The weekly programming allows up to seven distinct ON/OFF programs, supporting varied daily routines. An included random security feature helps mimic occupancy by shifting settings up to 30 minutes. This model accommodates LED, CFL, incandescent, and halogen fixtures, making it a versatile replacement for single-pole or three-way switches with a neutral wire.
BN-LINK 7 Day Programmable Timer (Blue Backlight)
This BN-LINK timer emphasizes visibility with a blue backlight and offers up to 18 ON/OFF programs across a 7-day schedule. It supports both single-pole and three-way configurations with a neutral wire. A backup battery preserves settings during outages, and Daylight Saving Time automatically adjusts to keep schedules accurate. Users can switch between AUTO and MANUAL modes to fine-tune lighting behavior when needed.
BN-LINK 7 Day Astronomical Timer
This BN-LINK model automates lighting based on sunrise and sunset times, using an adjustable time zone option to ensure accuracy. It supports 18 ON/OFF programs and seven-day planning, with short intervals as brief as one minute. DST and Random modes provide year-round convenience and security by creating a lived-in look when you’re away.
Leviton Decora Programmable Timer (VPT24-1PZ)
Leviton’s VPT24-1PZ combines an astronomical clock with flexible scheduling. It allows up to 49 ON/OFF events and supports both single-pole and multi-location setups when wired with a neutral. The built-in astronomical clock automatically adjusts for local sunrise and sunset, while a Daylight-Saving feature accounts for seasonal time changes, helping to optimize energy use and security across rooms.
BN-LINK 7 Day Programmable (No Backlight)
This BN-LINK model offers robust 18 ON/OFF programs with seven-day planning, and it can be set to operate automatically or manually. A backup battery maintains settings during outages, and the Daylight Savings Time mode ensures time alignment. The design is compatible with both lights and fans, promoting energy savings and predictable daily routines.
Honeywell Home ECONOswitch
Honeywell’s ECONOswitch emphasizes energy savings with a 7-day programmable schedule capable of controlling lights and motors. The model supports multiple device control within a single switch installation, making it suitable for fans and larger loads. Randomization and a fixed weekly program provide both security benefits and consistent daily lighting control across locations.
DEWENWILS 7-Day Timer
DEWENWILS offers a 7-day cycle with seven ON/OFF settings per day and a DST/RDM mode to provide random scheduling. The device requires a neutral wire and includes a backup battery for tenable programming during power interruptions. A straightforward interface makes it a practical option for bedrooms, living rooms, or home offices where consistent timing is desired.
Buying Guide
- Programming flexibility: Look for 7-day scheduling, 18- or 49-event options, and the ability to tailor times to weekdays versus weekends.
- Astronomical vs. fixed schedules: Astronomical timers automatically adjust for sunrise/sunset, reducing manual changes and improving energy management.
- Security features: Random or “vacation” modes mimic occupancy, helping deter intruders while you’re away.
- Power reliability: A backup battery preserves settings during outages, ensuring your automation remains intact.
- Wiring compatibility: Ensure the model supports single-pole or 3-way configurations and requires a neutral wire if needed for your circuit.
- Load compatibility: Confirm the timer can handle your lighting type (LED, CFL, incandescent) and any motor loads like fans.
- Ease of installation: Consider models with straightforward wiring, included accessories, and a visible, easy-to-program interface.
- Space and aesthetics: In-wall timers should fit standard electrical boxes and blend with wall plates for a seamless look.
