Solution Overview
Problem
Users, especially DIY homeowners, face difficulties in determining the proper wiring configuration for a new HVAC controller when replacing an existing one, due to the numerous possible configurations based on manufacturer, equipment type, and system settings.
Innovation Solution
A system with a communications port, memory storing wiring configurations, and a controller that communicates with a user interface to determine a new wiring configuration for a replacement HVAC controller based on the current configuration and selected replacement controller, using user inputs and a database to provide the correct wiring terminal connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually determines wiring configuration for a replacement HVAC controller, then the user can install the new controller, but the installation process becomes complex and error-prone due to numerous possible configurations
Solution Approach 1:
The patent introduces an intermediary system comprising a database storing wiring configuration data and a display device that translates between old and new controller wiring schemes. This intermediary automatically maps terminal connections based on stored configuration data, eliminating the need for users to manually determine complex wiring arrangements while ensuring accuracy.
Solution Approach 2:
The system performs preliminary action by pre-storing multiple wiring configuration scenarios in the database before installation. The configurations are prepared in advance based on different HVAC system types and controller models, so when installation time arrives, the user simply needs to input their specific system parameters and receive the pre-calculated wiring scheme.
2Reliability
If comprehensive wiring configuration data is stored for multiple HVAC controller types, then accurate wiring guidance can be provided, but the system complexity and data storage requirements increase
Solution Approach 1:
The configuration database is segmented into modular components, each representing a specific HVAC system type or controller model. Rather than storing one massive undifferentiated dataset, the system divides configurations into discrete, organized segments that can be independently managed and retrieved based on the user's specific installation scenario.
Solution Approach 2:
The database system is designed with universality to handle multiple HVAC controller types and wiring scenarios through a single integrated platform. The storage device and processing logic are configured to accommodate diverse configuration data formats and retrieval methods, allowing the same system to serve various controller models and system types without requiring separate dedicated systems for each.
3Measurement precision
If the system provides detailed wiring configuration information and troubleshooting data, then installation accuracy improves, but the information processing and display requirements increase
Solution Approach 1:
The system extracts only the essential wiring configuration parameters and troubleshooting information needed for the specific installation scenario from the comprehensive database. Rather than displaying or processing all available data, the system selectively retrieves and presents only the relevant subset of information based on the user's input parameters, reducing processing complexity while maintaining precision.
Data Source
AI summary
A wiring configuration tool may be configured to determine a new wiring configuration for a replacement HVAC controller based, at least in part, on the existing wiring configuration for a current HVAC controller and, for example, the make and model of the replacement HVAC controller. The wiring configuration tool may be hosted by a server that provides a user interface for interacting with the user. The user may access the wiring configuration tool via a web services interface, a smart phone application or in any other suitable manner.
