DIY Smart Thermostat with PIR. Retrofit universal wall switch for HVAC control.

The FCU Smart Thermostat Mini-Hornet Controller is a compact and intelligent HVAC control solution engineered for modern smart buildings, hotels, offices, and residential automation systems. Designed to manage Fan Coil Units (FCU) efficiently, it provides accurate room temperature regulation, optimized energy usage, and seamless automation integration.

Supporting both 2-pipe and 4-pipe FCU systems, the Mini-Hornet controller offers flexible 3-speed fan control, along with On/Off or 0–10V valve actuator control, making it suitable for a wide range of HVAC installations. The built-in temperature sensor ensures precise climate management, while smart algorithms maintain stable comfort levels with reduced energy consumption.

Integrated with S-BUS communication protocol, this thermostat easily connects to centralized BMS, PLC systems, and smart home controllers. Its compact design, intuitive interface, and modern aesthetics make it ideal for hotel rooms, commercial buildings, serviced apartments, and energy-efficient facilities.

Built with industrial-grade components, the Mini-Hornet Controller ensures long-term reliability, safe operation, and stable performance in demanding environments.
