TC300B-G Commercial Thermostat.

From commissioning to comfort, one thermostat feels right with every swipe: The Honeywell TC300B-G Commercial Thermostat supports a full range of fan coil equipment configurations

TC300B-G Thermostat is an advanced, highly configurable device providing building
automation connectivity well-suited for commercial building applications.
The product has
flexible I/O that will satisfy the needs of most 2-pipe or 4-pipe fan coil applications including floating, modulating, and 6-way Modulating valves plus multi-speed and variable speed fan and various external sensors with a minimum SKU complexity.

Other key supported functions include dehumidification w/reheat using an embedded humidity sensor, auxiliary heat functions, and more rapid transitional 2-pipe system seasonal changeover. This device supports BACnet MS/TP and Modbus communications via RS485 bus as is needed for typical HVAC building control systems. This same bus is used to facilitate future firmware updates and enhanced functionality as they are released to the market.
