Convenient for users
Give occupants “déjà view” with a swipeable color touchscreen that works like the mobile devices they already know.
TC300 Thermostat
Comfort at first swipe. From commissioning to comfort, one thermostat feels right with every swipe. The Honeywell TC300 Commercial Thermostat is built for fast, guided setup and connected, facility-wide visibility. Designed through hundreds of hours of testing, TC300 delivers a user experience that’s intuitive, responsive, and smart enough to adapt to occupant comfort preferences.
Professional capabilities that put everyone at ease
The TC300 Thermostat is a versatile building automation device designed for indoor commercial applications, especially 2-pipe or 4-pipe fan coil setups. It supports dehumidification, auxiliary heat functions, and quick transitional system changeover.
With flexible I/O, it meets a wide range of needs. TC300 enables BACnet MS/TP and Modbus (RS485) communications for HVAC control systems, allowing future updates. Intelligent control algorithms and scheduling balance energy efficiency and comfort, while a user-friendly color touch screen simplifies configuration and reduces reliance on technical manuals.
