The FT06 is a reliable, high-contrast digital LCD thermostat designed for standard commercial building upgrades. It provides a familiar, tactile interface combined with advanced BACnet/Modbus integration, ensuring long-term stability and ease of use for facility staff.

The FT06 represents a proven solution for standard commercial building climate control. Featuring a high-contrast digital LCD with intuitive soft-touch buttons, it provides a robust and cost-effective interface while maintaining the same professional-grade 0-10V modulating precision required for high-efficiency FCU systems.

Engineered for large-scale interoperability, the FT06 supports native BACnet MS/TP and Modbus RTU communication protocols. This allows the controller to be easily integrated into any standard Building Management System (BMS) via RS485, enabling centralized monitoring and intelligent energy management across multi-zone office buildings or hotels.

From student accommodation and retirement homes to modern corporate offices, the FT06 delivers consistent comfort and energy savings. Its simple installation process and durable hardware suite—including optional external sensors and keycard support—make it the preferred choice for Commercial HVAC Projects looking for a balance of performance and value.
