About TC300 Thermostat
TC300 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.
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
• 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. Support upto 10 Holidays
including floating or specific date. Support up to 10 special events including specific
date. For each holiday or special event can configure 3 period of 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
