Bryant Evolution SYSTXBBUID01--D

The Bryant SYSTXBBUID01-D Evolution™ Control is an intelligent communicating thermostat designed to manage a complete HVAC system, offering advanced comfort, versatility, and simplicity. It serves as the central command center for the Evolution System, replacing conventional thermostats and providing a single wall control for all system features.

Function Description:

The Evolution Control is the user interface for the Evolution System, which comprises several intelligent communicating components, including variable-speed furnaces or FE fan coils, 2-stage AC or heat pumps, and Evolution Packaged Products. These components continuously communicate via a four-wire ABCD bus, exchanging commands, operating conditions, and other data to optimize system performance.

The control supports various system configurations, including communicating indoor and outdoor units, or communicating indoor units with standard 24VAC controlled outdoor units. It also integrates with accessories such as humidifiers, ventilators, and UV lights. When conventional outdoor units are used, the Evolution furnace or fan coil provides the necessary 24-volt signals for control. Additionally, the Evolution Network Interface Module (NIM) allows for the connection of a Bryant HRV or ERV without requiring a separate wall control.

The system offers precise temperature and humidity control, with advanced features like variable-speed operation for furnaces and fan coils, multi-stage heating and cooling, controlled ventilation, humidification, dehumidification, and air quality management.

Usage Features:

The Evolution Control is designed for user-friendly operation, providing homeowners with comprehensive control over their HVAC system.

Temperature and Humidity Control: Users can set desired heating and cooling temperatures, as well as humidity levels. The system can automatically adjust airflow for dehumidification based on demand, and even overcool the space if necessary to meet humidity targets.
Programming: The control allows for programmable schedules, enabling users to set different temperatures and fan operations for various periods of the day (e.g., WAKE, DAY, EVENING, SLEEP) and for specific days or the entire week. A "Quick Start" option facilitates initial setup of day, time, and desired humidity.
Auto Mode: An Auto Changeover mode automatically switches between heating and cooling as needed, with an adjustable time delay to prevent rapid cycling.
Smart Recovery: When enabled, Smart Recovery gradually adjusts the room temperature to reach the desired setpoint by the scheduled time, starting the recovery process up to 1.5 hours in advance.
Fan Operation: Users can select continuous fan operation at different speeds (Low, Med, High) or set it to Auto, where the fan runs only during equipment operation.
Override Functions: The system allows for temporary overrides of the temperature schedule, with adjustable override times or an indefinite hold.
Heat Source Selection: For hybrid heat or hydronic heat applications, users can manually select the desired heat source or allow the system to automatically manage it.
Keypad Lockout: A keypad lockout feature prevents unauthorized changes to settings.
Display: The user interface features a clear display that shows current operating status, system messages, and allows for navigation through various menus. It can display temperatures in either Fahrenheit or Celsius.
Remote Room Sensor: An optional remote room sensor can be used to provide temperature readings, allowing the main control to be mounted in less optimal airflow areas.
G Terminal Functionality: The G terminal can be configured for various operations, including enabling the fan for fresh air supply products, running the fan at a selected speed, or initiating a system shutdown in response to an external device (e.g., a float switch).
Dehum Drain: This feature turns off the continuous fan for five minutes at the end of a cooling cycle to drain water from the indoor coil, improving dehumidification effectiveness.
Reheat Dehum: Available with fan coil systems, this function enables electric heat to be used during "Cool to Dehumidify" operation, significantly improving humidity control in cooling mode.

Maintenance Features:

The Evolution Control provides several features to assist with system maintenance and troubleshooting.

Filter and UV Light Notifications: The system can be configured to remind the homeowner when it's time to clean or change the air filter, humidifier pad, ventilator pre-filter, or UV lights, based on adjustable time intervals or actual operation time.
Static Pressure Check: During initial installation or when the INSTALL menu is run, the system performs a static pressure check to ensure proper airflow. It also monitors static pressure every 24 hours to detect filter accumulation (TrueSense™ Dirty Filter Detection).
Frozen Coil Detection: The user interface monitors system static pressure during cooling operation. If a dramatic increase is detected, it will temporarily turn off cooling, record a fault, and run the fan at a reduced airflow to prevent coil freezing.
System Malfunction Screen: In case of a system fault, the control displays a "SYSTEM MALFUNCTION" message on the main screen, along with a code number corresponding to the fault on the circuit board of the affected component (fan coil, furnace, or outdoor unit).
Last 10 System Events: The "Service Info" menu provides a history of the last 10 system events, including the time and date of each incident, helping technicians diagnose issues.
Run/Fault History: The system tracks resettable fault counters, cycle counters (number of heat/cool/power cycles), lifetime hours of operation, and kilowatt-hours used for electric reheat.
Model/Serial Numbers: The "Service Info" menu allows installers to view the model and serial numbers of communicating equipment in the system.
Service Phone Number: Installers can enter a name and phone number for service, which will appear on pop-up messages for homeowners.
Installer/Service Menus: These menus provide vital information for installers and service personnel, including equipment summaries, setup options, checkout procedures for testing equipment operation, and service information like fault history.
Reset Factory Defaults: Options are available to reset program schedules, user settings, and installation settings to their factory defaults.
Service Tool Mode: A -D model user interface can be used as a service tool, taking over system control and allowing technicians to diagnose and configure the system without affecting the regular user interface settings.
