BN-LINK SU101C-2P 7-Day In-Wall Timer Switch, 18 Programs, 2-Pack

With a 7-day programmable format, the BN-LINK SU101C-2P timer switch lets you schedule lights and fans around your routine. Set up to 18 ON/OFF programs, choose individual days or preset day combinations, and set intervals as short as one minute. The two-pack gives you timer control for more than one location.

Its in-wall design works with single-pole or 3-way wiring, so you can set up scheduled control in places such as hallways, stairways, and entryways. A neutral wire is required for installation.

Key features

Use the timer’s automatic mode to turn connected lights or fans on and off according to your schedule. Daylight Saving Time functionality helps keep the clock aligned when the time changes, while manual mode lets you switch between scheduled and direct control. The built-in rechargeable battery preserves settings during a power outage.

Random mode delays scheduled on and off times by 0–30 minutes, creating a lived-in lighting pattern while you’re away. The display has no backlight, which helps reduce light in a room at night. The switch is rated for 15A/1875W and is ETL Listed. A wall plate and wire nuts are included.

Buyer feedback highlights functionality and reliability, while experiences with programming, instructions, and ease of use are mixed. The 18-program schedule, automatic mode, and manual controls provide a flexible way to manage recurring lighting routines.

Getting the most from it

Before installation, make sure the wiring includes a neutral wire. This switch is designed for indoor installation and works with single-pole or 3-way setups using compatible SPDT switches. It can control outdoor lights when the timer itself is installed indoors, such as a porch light operated from an entryway.

After setup, select AUTO for scheduled operation or MANUAL for direct on/off control. For a consistent routine, assign programs to individual days or a preset combination of days and check that scheduled times do not overlap. If you use Random mode, account for its 0–30-minute shifts when planning when lights turn on and off.

Everyday use

Set entryway or hallway lights to follow your usual arrival and departure times, or program a fan to operate on a weekly schedule. The timer’s short interval options are useful when you want more control than a basic switch provides, while day-specific scheduling can accommodate routines that change between weekdays and weekends. For travel, Random mode adds variation to scheduled lighting without requiring daily manual operation.

The two-switch pack is useful when you want to add timer control at separate points in the home. In a 3-way arrangement, the timer can control the same light from two locations, making it suitable for spaces such as stairways, garages, and larger rooms. Match the wiring setup and connected load to the switch’s ratings when planning installation.

Final verdict

Choose the BN-LINK SU101C-2P when you want programmable in-wall control for lights or fans, with a weekly schedule, manual operation, and an away-mode option. Its 3-way compatibility supports control from two locations, and the two-pack helps extend scheduled lighting to more than one area. It’s a practical fit for indoor routines such as managing entryway, hallway, or porch lighting from an indoor switch location.
