A: The thermostat supports SylkTM, BACnet MS/TP over RS485, and Modbus RTU communication technologies.

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

Colour, 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.
An LED ring indicator to show the operational status.
Real-time clock timekeeping accuracy with 72-hour retention during power loss.
A 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.
