Innovation Solution
An HVAC controller with a guided setup routine that includes multiple screens to help users configure the system, displaying selectable options for HVAC configuration settings and corresponding wiring configurations, allowing users to identify their system type and wiring connections, thereby facilitating the setup process without requiring extensive technical knowledge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional HVAC controller installation process is used, then the controller can control the HVAC system, but the user faces challenges in configuring it due to limited knowledge of existing HVAC system configurations
Solution Approach 1:
The HVAC controller performs self-detection of the existing system configuration by automatically sensing wiring connections and system parameters. The controller configures itself without requiring the user to have specialized knowledge, transforming a knowledge-dependent manual configuration process into an automated self-service process that guides users through simple selection steps while the controller handles the complex detection and configuration internally
Solution Approach 2:
The controller implements a feedback mechanism where it detects the actual wiring configuration and system parameters, then uses this information to automatically adjust its configuration settings. The system provides feedback to the user through the setup routine, showing detected parameters and allowing verification or correction, ensuring the final configuration matches the actual physical system
2Measurement precision
If the user manually determines wiring configurations, then accurate system configuration can be achieved, but the process becomes complex and time-consuming for users with limited technical knowledge
Solution Approach 1:
The patent replaces the manual mechanical process of determining wiring configurations (where users physically trace wires and identify connections) with an automated electronic detection system. The controller uses electrical sensing to automatically identify wiring configurations, substituting complex manual procedures with simple electronic measurements that the user only needs to initiate through the guided setup routine
Solution Approach 2:
The controller performs preliminary detection and identification of system parameters during the initial setup phase before full operation begins. The self-detection process proactively gathers all necessary configuration information upfront, eliminating the need for users to perform complex determination steps during installation and reducing the overall complexity of the setup process

AI summary
An HVAC controller may be programmed to execute a guided set up routine that may guide a user through configuring the thermostat to control a particular HVAC system configuration based, at least in part, on which wires from the HVAC system are connected to terminals of the HVAC controller. The guided set-up routine may be accessible through a user interface provided at a remote device that a user may utilize to interact with the HVAC controller from a remote location.
