Trust ABST-604

The Trust ABST‑604 dusk‑dawn sensor solves a common problem: remembering to switch exterior or interior lights on or off at the right time. Once installed — no wiring needed — it automatically measures ambient light and triggers your lighting (or other devices) when daylight fades, and switches them off when daylight returns, or after a preset interval of 2 to 8 hours. This ensures convenience, safety and energy savings — especially useful for garden lights, pathway lamps, outdoor décor, or regular household lighting. dezlwerqy1h00.cloudfront.net+2switch-in.eu+2

Because it’s battery‑powered (2 × AAA) and uses wireless RF communication, ABST‑604 can be placed anywhere: mounted on a wall, under eaves, on a balcony — inside or outside. That flexibility makes it ideal for retrofits, rentals or homes where wiring is impractical. It pairs with any compatible 433.92 MHz receiver from the Trust Smart Home / “Start‑Line” product family. Once paired, the system works reliably day after day without intervention. ManualsLib+2Warmteservice+2

Compared to manual switches or timer‑only solutions, ABST‑604 is smarter — it adapts to actual daylight rather than fixed clock times, so lighting reflects real light conditions even if sunrise/sunset times change. For households, offices or outdoor spaces in Bangladesh, it makes lighting automation effortless, reduces electricity waste, and increases security and comfort.
