Buying Guide: Key Purchase Considerations
- Programming capacity: Consider how many on/off events you need per week. Models range from basic weekly programs to 49 events with multi-day scheduling.
- Astronomical vs. fixed time: Astronomical timers adjust for sunrise/sunset automatically, which is beneficial for outdoor lighting and seasonal changes.
- Random occupancy mode: A random or vacation mode helps simulate activity when you’re away, enhancing security.
- Manual vs. auto modes: Quick access to manual control can be useful when you need immediate lighting without changing schedules.
- Power-outage memory: Check for backup batteries to preserve settings during outages, especially in areas with unstable power.
- Compatibility: Confirm compatibility with single-pole or 3-way setups and ensure a neutral wire is available when required.
- Installation: Look for models that match your wall box type and wiring configuration to simplify installation.
- Energy impact: A programmable timer should meaningfully reduce unnecessary runtime for lights and motors to maximize savings.
