The FT-CS08 is a professional HVAC controller designed for large-scale commercial integration, available in either BACnet MS/TP or Modbus RTU communication versions. It prioritizes network stability and data transparency, allowing facility managers to monitor and control multi-zone environments from a centralized Building Management System (BMS).

The FT-CS08 represents the next generation of building climate control. Designed with an ultra-slim profile and a vivid capacitive touchscreen, it offers a premium user interface while delivering the 0-10V modulating precision required for modern high-efficiency FCU systems.

The FT-CS08 provides exceptional flexibility for building automation. Depending on your project requirements, it can be configured with either BACnet MS/TP or Modbus RTU communication protocols. This ensures reliable integration with diverse Building Management Systems (BMS), allowing facility managers to monitor and control HVAC units with precision.

By utilizing the optional Occupancy Sensor and EC Motor support, this controller helps buildings meet strict energy-saving standards (such as LEED or BREEAM). The intuitive logic automatically adjusts setpoints based on room occupancy, ensuring comfort for occupants while eliminating energy waste in vacant areas.
Global Protocol Integration: Fully compatible with BACnet MS/TP and Modbus RTU, making it a "plug-and-play" terminal for any modern Building Management System (BMS).
Energy-Saving 0-10V Control: Specifically engineered to control EC fans and modulating valves via 0-10V signals, reducing energy waste and ensuring ultra-quiet operation.
Versatile System Support: Easily switch between 2-pipe and 4-pipe heating/cooling modes.
Smart Life Ecosystem: Supports remote monitoring via mobile app and voice control through Amazon Alexa and Google Home.
Hospitality Optimization: Features dedicated inputs for Keycard (Occupancy) and external sensors, perfect for hotel energy management and cost reduction.


Our FT-CS08 controller is engineered to meet the highest international standards for safety, reliability, and environmental responsibility:
Safety & EMC: Fully compliant with CE (RED/LVD/EMC), UKCA, FCC, and ETL Listed standards.
Environmental: Certified by RoHS and REACH, ensuring lead-free and eco-friendly manufacturing.
Quality Management: Produced in an ISO 9001:2015 and ISO 14001:2015 certified facility.
