BN-LINK Astronomical In-Wall Timer Switch, 7-Day Programmable for Sunrise and Sunset

The BN-LINK 7-Day Programmable Astronomical In-Wall Timer Switch automates lighting around local sunrise and sunset, with up to 18 on/off programs and single-pole, neutral-wire installation.

• Local sunrise and sunset scheduling — automate lighting after setup without daily manual changes.
• Up to 18 on/off programs, with 7-day options — set schedules for selected days or preset day combinations.
• One-minute minimum program length — create short or longer lighting schedules.
• Random mode and automatic daylight saving time adjustment — vary schedules while away and keep the clock aligned when daylight saving time changes.
• ETL listed; rated for 125VAC, 60Hz — choose a timer with defined electrical ratings.
• Neutral wire required; single-pole circuits only — identify the correct wiring setup before installation.

For porch, entryway, hallway, garage, patio, outdoor and ceiling-fan lighting, remembering to switch lights on and off can become part of the daily routine. This in-wall timer is designed to take over scheduled control, including lighting that follows the changing sunrise and sunset times in your local area. Set it up for your time zone, choose the programming that suits your week, and use the controls on the front cover when you want to switch operation directly.

How does the astronomical timer schedule lights?

The timer calculates on and off times from local sunrise and sunset after setup. Select the correct time zone so the calculation matches your location; six presets are available: PAC, MOU, CEN, EAS, HAW and ALA. This astronomical schedule is intended for lights whose timing needs to follow daylight through the year, rather than remain at one fixed clock time.

You can also create standard weekly schedules, choosing individual days or one of the available preset day combinations. With up to 18 on/off programs and a shortest program length of one minute, the switch accommodates multiple programmed events and precise schedule intervals.

• Automatic local sunrise and sunset-based switching after setup.
• Six selectable time-zone presets: PAC, MOU, CEN, EAS, HAW and ALA.
• Seven-day scheduling with individual-day or preset-combination options.

What control and away modes does it offer?

Choose AUTO for scheduled operation or MANUAL for direct on/off control by pressing and holding the front cover. Random mode varies the light schedule to create the appearance that a home is occupied while you are away, which is intended to help deter potential intruders.

The daylight saving time mode automatically adjusts the clock when changing between daylight saving time and standard time. A built-in backup battery helps retain your settings during power outages, reducing the need to re-enter saved programming after an interruption.

• AUTO mode follows programmed schedules; MANUAL mode provides direct control.
• Random mode varies lighting times while away.
• DST mode adjusts the clock for daylight saving time changes.
• Built-in backup battery helps preserve settings during power outages.

Will this timer work with my wiring and lighting load?

The BN-LINK timer is for single-pole installations and requires a neutral wire. It is ETL listed and rated at 15A/1875W for resistive loads, 10A/1250W for tungsten loads, 10A/1250W for ballast loads, and 1/2HP, at 125VAC and 60Hz. Confirm that your wiring type and connected load match these requirements before installation.

It is intended for lighting and compatible applications such as porch, entryway, hallway, garage, patio and outdoor lights, as well as ceiling fans. The different load ratings matter when matching the switch to the type of equipment being controlled.

• Installation type: single pole only.
• Wiring requirement: neutral wire.
• Electrical supply: 125VAC, 60Hz.
• Load ratings: 15A/1875W resistive; 10A/1250W tungsten; 10A/1250W ballast; 1/2HP.

What warranty and guarantee come with the switch?

BN-LINK provides a 12-month warranty and a 30-day money-back guarantee for this timer switch. These terms accompany a programmable control intended for routine indoor and outdoor lighting schedules, with manual operation available when a scheduled setting is not needed.

The BN-LINK timer suits people who want weekly light schedules, sunrise-and-sunset automation or randomized lighting while away, provided their installation is single pole with a neutral wire and the connected load falls within its ratings. Its combination of astronomical scheduling, manual control and multiple weekly programs gives these buyers several ways to manage compatible lights from an in-wall switch.
