The FT-66 is an advanced glass panel thermostat engineered for hotel guestrooms, featuring keycard occupancy support and EC fan control for maximum energy savings. For exploring more commercial building solutions, view our complete portfolio of BACnet MS/TP Thermostats.
The FT-66 is a modern glass panel LCD controller specifically engineered for the hospitality industry and intelligent office spaces. It focuses on maximizing energy savings without compromising guest comfort, serving as a critical endpoint in your Commercial HVAC Control strategy.

The FT-66 is designed for modern luxury hotels. Available in sleek black and minimalist white, this Hotel Energy-Saving Thermostat features a premium scratch-resistant glass panel that provides guests with a seamless and upscale climate control experience.

To meet modern Green Building standards, the FT-66 features specialized inputs for occupancy sensors or hotel keycards. This intelligent logic detects when a room is vacant, automatically adjusting setpoints to eco-mode, significantly reducing unnecessary HVAC energy waste in hotels and dormitories.

The FT-66 supports native BACnet MS/TP and Modbus RTU protocols over an RS485 network. This allows facility managers to monitor room temperatures, adjust setpoints globally, and track HVAC performance from a centralized Building Management System (BMS).
