iCONstant HT Continuous Running dMEV Extract Fan – Intelligent Humidistat & Timer for Low-Energy Ventilation

The iCONstant HT White Extract Fan offers continuous, low-noise ventilation with automatic humidity control and adjustable timer settings. Designed for new builds and refurbishments, this IPX5-rated unit ensures energy-efficient performance and compliance with Building Regulations.

• Continuous Background Ventilation: Operates with selectable trickle speeds of 6, 8, or 13 l/sec to maintain healthy air quality around the clock.
• Smart Boost Function: Boosts airflow up to 20 l/sec when humidity exceeds the set level, with manual override via pullcord or remote switch.
• Adjustable Humidistat: Built-in humidity sensor adjustable from 60% to 90% RH activates boost when moisture levels rise.
• Customisable Timer: Overrun timer activates once humidity drops, with selectable durations of 2, 15, 30, or 45 minutes for efficient post-use extraction.
• Ultra-Quiet Operation: Whisper-quiet performance from just 10 dB(A), perfect for bathrooms, kitchens, and other sensitive spaces.
• Low Energy Consumption: 24V DC motor uses as little as 1.21W at 6 l/sec trickle speed—cheaper to run than a low-energy bulb.
• Smart Diagnostics: Features a unique setup LED for easy configuration and maintains all settings during power interruptions.
• Reliable Extraction: Flow sensor ensures consistent performance regardless of environmental conditions.
• Versatile Design: Circular, minimalist appearance suitable for wall or ceiling mounting.
