Description
TC300 Thermostat is an advanced, highly configurable device providing building automation connectivity well-suited for indoor commercial building applications. The product has flexible I/O that will satisfy the needs of most 2-pipe or 4-Pipe fan coil applications. 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. The integral intelligent control algorithms plus scheduling help to achieve the perfect balance between Energy Efficiency and Comfort. The thermostat utilizes an attractive, color, capacitive-touch screen interface providing an intuitive configuration process with minimal installer training. This functionality is enhanced through the usage of embedded help screens reducing reliance on technical manuals for complex installation.
FEATURES AND BENEFITS • Color, capacitive-touch screen display for intuitive, fast commissioning and exceptional user experience. • Multiple, configurable user types with customizable privileges to prevent unauthorized usage. • Embedded system monitoring screen for equipment and I/O status. • Customizable daily schedule for Occupancy set points, up to "X" Holidays including floating, and up to 3 special events. • Advanced commercial control algorithms such as auto changeover. • Customizable inactive display modes, Auto dim display, always on, or dark mode. • A LED ring indicator to show the operational status. • Real-Time Clock time keeping accuracy with 72 hour retention during power loss. • Thermostat can be configured via HMI, or BACnet.
EQUIPMENT CONTROL FEATURES • Fan coil, On/Off Valve, Floating Valve, Modulating Valve, and 6-Way Modulating Valve. • Discharge Air Control • 1-3 or variable speed fan • Dehumidification with and without reheat. • Enhanced 2-Pipe fan coil functionality during seasonal or system changeover providing heating or cooling functionality before CW/HW has reached optimal operating temperature. • Service mode for manually enabling outputs for faster diagnostics and equipment testing. • Auxiliary heating options supporting peripheral or supplemental types • Auto mode to switch between heating and cooling according to the current space temperature • Staging control, PID Tuning, DAT Lockout, Modulating control • System Switch and Ventilation options. • Integration with a variety of external wired sensor types including: Discharge air, Drain pan, occupancy, Proof or airflow, Space temp, CO2, and Humidity. • Complies with ASHRAE guideline 36-2021, Section 5.22 sequence of operations for high-performance operation when using floating/modulating valves and multi-speed/variable speed fan.
