Carrier SYSTXBBECC01-B Control

The Carrier SYSTXBBECC01-B Evolution Connex Control is a highly advanced, 4-wire communicating wall control designed for seamless integration with Evolution-rated indoor equipment. As a veteran technician knows, this Series B model is critical for unlocking the full potential of variable-speed HVAC systems, providing precise management of temperature, humidity, and airflow. It features occupancy sensing technology to automatically adjust comfort profiles based on room activity, optimizing energy efficiency without manual intervention. The full-color touchscreen interface supports 7-day programmability and zoning capability for up to eight distinct zones without the need for a bypass damper or field-installed power transformer. With integrated Wi-Fi connectivity, this control manages Perfect Humidity and Perfect Heat technologies while offering Hybrid Heat system management for dual-fuel applications. Its self-configuring logic ensures accurate system discovery and diagnostics, significantly reducing installation time and preventing configuration errors in the field.

• Advanced System Communication: Utilizes a 4-wire connection to synchronize with Evolution Series furnaces, fan coils, and heat pumps for optimized staging.
• Enhanced Humidity Control: Leverages Perfect Humidity technology to manage staging-capable cooling equipment for superior dehumidification and comfort.
• Zoning Efficiency: Supports up to 8 zones of customized climate control, compatible with Evolution Zoning systems for precise airflow management.
• Intuitive Diagnostics: Built-in TrueSense Dirty Filter Detection and system self-configuration tools streamline maintenance and troubleshooting for contractors.
• Remote Management: Provides robust Wi-Fi remote access and is compatible with Amazon Alexa for modern home automation integration.

Is the SYSTXBBECC01-B backward compatible with older Series A software?
No, this is a Series B control. Software updates are specific to this hardware series; Series A software cannot be used on Series B units and vice versa. Always use a FAT32-formatted MicroSD card for manual firmware updates.

Does this control require a separate power transformer for zoned applications?
When paired with an Evolution Zoning System, the control draws power directly from the 24VAC ABCD equipment bus, eliminating the need for an external field-installed transformer or LAT sensor.

How does occupancy sensing affect the programmed schedule?
When enabled, the occupancy sensor can override the "Home" or "Wake" activities, shifting the system to "Away" settings if no motion is detected, thereby maximizing energy savings during unoccupied periods.
