User Interface Faults

Identifies common faults related to the User Interface and its sensors.

This document describes the Bryant Evolution™ Control, a sophisticated user interface that serves as the command center for the Evolution Zone System. This system integrates various intelligent communicating components, including the Evolution Zone Control (User Interface), Smart Sensors, a Damper Control Module, variable-speed furnaces or FE fan coils, 2-stage AC or HP units, and Evolution Packaged Products. These components continuously communicate via a four-wire ABCD bus, exchanging commands, operating conditions, and other data to provide enhanced comfort, versatility, and simplicity.

Function Description

The Evolution Zone Control replaces conventional thermostats, offering a single wall control for all system features. It manages controlled ventilation, humidification, dehumidification, and air quality. The system supports both Evolution 2-stage (communicating) and standard 24VAC controlled outdoor units. When conventional outdoor units are used, the Evolution furnace or fan coil provides the necessary 24-volt signals. The Damper Control Module (P/N SYSTXBB4ZC01) allows connection of a Bryant HRV or ERV without a separate wall control.

The Evolution Zone system is designed to operate without a bypass damper, leveraging its intelligence and variable-speed motor technology. For optimal performance, zones should be sized to deliver at least the minimum airflow for the system in both heating and cooling modes, and ductwork should be oversized by 25% to minimize noise at minimum zone airflow.

The Evolution Zone Control acts as the primary temperature sensor for Zone 1 and should be located in a frequently used, easily accessible, and visible area, preferably on an inside partitioning wall without pipes or ductwork. It should be mounted approximately 5 feet (1.5 meters) from the floor and away from direct light, heat sources, supply registers, or areas with poor air circulation to ensure accurate temperature measurement.

A Remote Room Sensor can be used in place of the User Interface's internal temperature sensor, allowing the Evolution Zone Control to be mounted in less-than-optimal airflow areas. The remote sensor connects to the User Interface backplate (S1 and S2) or the Damper Control Module (OS1 and OS1C) and is automatically detected by the Evolution Zone Control. It's important to note that the humidity sensor cannot be remotely located. Smart Sensors can also be used in any zone, providing a temperature display and buttons to adjust the desired temperature, as well as displaying outdoor temperature and indoor humidity sensed at the User Interface.

Usage Features

The Evolution Zone Control offers a comprehensive set of features for managing home comfort:

Initial Power-Up and System Commissioning: Upon initial power-up, the User Interface automatically establishes communication with and identifies all Evolution components. It guides the installer through a sequence of screens to select accessories (air filter type, humidifier, UV lights) and verify equipment.
Static Pressure Check: After setup, the system performs a static pressure check by opening all dampers and running the blower at its expected highest delivered airflow. This process takes about 1.5 minutes and helps identify potential issues if static pressure exceeds 1 inch.
Duct Assessment: The system measures the relative size of the ductwork and damper leakage for each zone. This assessment occurs automatically each day at a user-selectable time (default 1:00 p.m.) and overrides any active heating or cooling calls. It helps the system calculate the relative size of each zone and the percentage of leakage through the dampers, ensuring correct airflow distribution.
Quick Start: For first-time installers, a Quick Start option allows for rapid system setup, including setting the day, time, and desired heating and cooling humidity levels.
Scheduling: Users can create program schedules for all days of the week, including WAKE, DAY, EVENING, and SLEEP periods, with adjustable start times and temperature setpoints. The system also allows for temporary overrides of the temperature schedule for a specified duration or indefinitely using the HOLD button.
Install/Service Menus: These menus provide vital information for installers and service personnel, including equipment summary, installation settings, setup options, checkout procedures, and service information.
Thermostat Setup: This menu allows modification of various thermostat settings, such as Auto Mode (enable/disable and changeover time), Heat/Cool Deadband (minimum temperature difference), Offsets (calibration of temperature and humidity sensors), Cycles Per Hour (maximum cycles and anticipator sensitivity), and Programming (enable/disable program schedule, periods per day, programmable fan on/off).
Furnace Setup: This menu allows adjustment of furnace airflow (COMFORT, EFFICIENCY, MAXIMUM), dehumidification airflow (NORMAL, HIGH), low heat rise, and staging (SYSTEM, LOW, HIGH).
Heat Pump/AC Setup: This menu includes settings for cooling lockout, low ambient cooling, entered size of the outdoor unit, and defrost interval.
Zoning Setup: Users can disable zoning, adjust zone temperature offsets, and set airflow limits for each zone (LOW, MEDIUM, HIGH, MAXIMUM) to manage noise and comfort.
Utility Saver: This feature controls the equipment's response when a utility saver input is active, offering options to turn off equipment or run at a low stage.
Checkout Menus: These menus allow testing of equipment operation, including furnace, heat pump heating/cooling, humidifier, ventilator, and zoning functions.
Service Menus: These menus provide access to equipment status (furnace, heat pump), last 10 system events, run/fault history, today's date, model/serial numbers, and service phone number.
Operational Information: This section details various operational aspects, such as zone selection, continuous fan operation (AUTO, LOW, MED, HIGH), five-minute compressor timeguard, emergency heat activation, heat source selection (Hybrid or Hydronic Heat), keypad lockout, and heat/cool LED indicators.
Equipment Cycle Timer: Prevents rapid cycling of heating or cooling, ensuring equipment operates for a minimum duration.
Staging Timer: Prevents higher stages from activating until the preceding stage has run for a minimum of 10 minutes.
Three-Minute Minimum On Time: Ensures that a stage remains on for at least three minutes once activated.
Heat/Cool Setpoints: Enforces a minimum temperature difference between heating and cooling setpoints.
Temperature Display: Rounds the actual temperature towards the setpoint for display purposes.
Auto Changeover: Manages transitions between heating and cooling modes with an adjustable time delay.
Smart Recovery: Gradually adjusts room temperature to achieve the desired setpoint before a scheduled recovery time.
Media Filter: Performs a static pressure check of the system every 24 hours to monitor filter accumulation.
Unoccupied Zones: Allows selected zones to be set to an unoccupied status, functioning as dump zones to alleviate high static pressure or noise.
Frozen Coil Detection: Monitors static pressure during cooling and turns off cooling for up to an hour if pressure increases dramatically, preventing coil freezing.
Airflow Limits and Equipment Protection: Manages maximum airflow into zones based on their relative size and selected airflow limits, taking steps to reduce airflow or dump air to other zones if necessary.
Dehumidify Operation: Controls dehumidification by allowing overcooling or reducing airflow based on humidity demand and AC airflow settings.
Hybrid Heat Setup/Operation: Manages furnace and heat pump lockout temperatures and defrost cycles in hybrid heat systems.

Maintenance Features

The Evolution Zone Control includes several features to assist with system maintenance:

Filter Type and Clean Interval: Users can select the air filter type (MEDIA, EAC, MEDIA+EAC) and set a clean interval (30 to 180 days of blower operation). The system will notify the homeowner when it's time to clean or replace the filter.
Humidifier Pad Change Interval: If a humidifier is installed, users can set an interval (1 to 24 months) for notification to change the humidifier pad.
Ventilator Clean Interval: If a ventilator is installed, users can set a clean interval (60 to 180 days of operation) for pre-filter notification.
UV Lights Change Interval: If UV lights are installed, users can set an interval (6 to 48 months) for notification to change the UV lights.
Remind Owner of Routine Maintenance Every: This setting allows adjustment of the timer interval (6 to 24 months) for the normal System Maintenance notification to the homeowner.
Last 10 System Events: This menu displays the last 10 events that occurred throughout the system, with time and date stamps, helping technicians diagnose issues. These events are stored in the User Interface's memory and can be reset.
Run/Fault History: This information, stored in the equipment circuit boards, provides fault counters and the number of heat/cool/power cycles the unit has performed, aiding in long-term maintenance tracking.
Service Phone Number: Allows the installer to enter a name and phone number that will appear to the homeowner when a service reminder pop-up message is displayed, facilitating easy contact for future service.
System Malfunction Screen: Displays flash codes from the circuit boards of the fan coil, furnace, or outdoor unit, indicating specific faults. This screen also shows active faults to the homeowner and provides a service phone number to call. The user can dismiss the notice, and the regular run mode screen will reappear, but "SYSTEM MALFUNCTION" will remain until the error code disappears.
