Features
Fully Automated Smart Operation
- Adapts to humidity and movement levels using an advanced algorithm—no manual adjustments required.
- Ensures optimal ventilation, noise control, and power consumption based on real-time conditions.
Dual Functionality – Intermittent or Continuous Operation
- Intermittent Mode: Activates automatically when humidity levels rise, dynamically adjusting fan speed until moisture drops below the set threshold.
- Presence Detection: When movement is detected, the fan operates at 75% of its maximum speed for an adjustable run-on time of either 2 minutes (for bathrooms <4m²) or 15 minutes.
- Continuous Mode: Runs at a constant low speed, boosting automatically when required.
Smart Dual-Sensing Technology
- Automatically detects motion and humidity changes, activating the most efficient ventilation mode to reduce energy consumption and noise levels.
Enhanced Airflow with Dual Inlets
- Front and side air intakes improve aerodynamic performance, delivering higher pressure at lower flow rates while maintaining a sleek, slimline design.
Easy Dual-Wire Installation
- Simple 2-wire connection for quick and hassle-free setup.
