Intelligent Energy Management & Occupancy Sensing

The FT-66 excels in energy conservation through its integrated Keycard (Occupancy) support, making it an ideal choice for high-end hospitality environments. While this model features a premium scratch-resistant glass panel for a superior tactile experience, it utilizes the same industry-leading 0-10V modulating technology found across our professional range.

For projects requiring a more budget-friendly solution without compromising on performance, we recommend our FT-08 Series, which offers the same high-standard HVAC control logic in a cost-effective physical-button design. This allows project managers the flexibility to choose between luxury glass aesthetics or economic alternatives for large-scale commercial installations.
