Product Description
STEINEL TTS PRO is a twilight switch with a timer, COM1 relay and Bluetooth Mesh. It combines brightness-based control of wired lighting with scheduling in the STEINEL Connect app. Suitable for entrances, façades, courtyards and shop windows where lighting should also follow opening hours. This is the anthracite version (089139).
Practical features
- 1–1000 lx threshold and Teach-in: set the required switching brightness in the app or store the current ambient-light level.
- Schedules in the STEINEL Connect app: adjust operation to the time of day and required days. Night economy mode lets you switch lights off when they are not needed.
- Real-time clock with a 7-day backup: the clock continues during a temporary power failure. This reserve does not supply power to the luminaires.
- COM1 relay and Bluetooth Mesh: the relay switches connected lights on and off; Bluetooth provides settings and networking with compatible STEINEL Connect devices.
- IP54 and UV-resistant plastic: the splash-protected housing is suitable for outdoor installation. Compact dimensions: 95 × 95 × 38 mm (width × height × depth).
TTS PRO detects ambient brightness; it is not a motion sensor. If you only need a Bluetooth control signal for a compatible STEINEL network, without a local load relay, consider TCL PRO.
Installation: surface mounting on a wall, with a 220–240 V / 50–60 Hz supply. Choose a position where the sensor can detect ambient daylight without direct illumination from the light it controls. Operating temperature: −20 to +40 °C; own consumption: 0.5 W. 5-year manufacturer warranty, subject to STEINEL’s terms.
Delivery: 2–3 business days.
Also available in white.
