Solution Overview
Problem
HVAC control systems face challenges in scalability, ease of use, and cost-effectiveness, particularly in managing multiple thermostats and HVAC units across various building types, requiring a solution for remote control and centralized monitoring.
Innovation Solution
A web-enabled HVAC control system with a controller that communicates over networks, providing a web server to display customizable information and allowing remote access and configuration of thermostats, enabling centralized control and monitoring through web pages for scheduling, alarm management, and system configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple thermostats and HVAC units are managed in larger buildings, then system coverage and functionality are improved, but device complexity and installation difficulty increase
Solution Approach 1:
The system divides the HVAC control into multiple independent thermostats, each managing a specific zone or area. Each thermostat operates as an autonomous unit with its own web server, allowing the system to scale to large buildings without increasing overall complexity. The segmentation enables modular installation and maintenance.
Solution Approach 2:
Each thermostat is designed as a universal controller that can manage different types of HVAC equipment (heating, cooling, ventilation) and can be deployed in various building types (residential, commercial, large-scale). The web-enabled interface provides multi-functional access for monitoring, control, and configuration across the entire system.
2Productivity
If centralized control of multiple HVAC units is implemented, then operational efficiency is improved, but ease of operation and monitoring deteriorate due to system complexity
Solution Approach 1:
A web server acts as an intermediary between the user and the HVAC system. It provides a standardized web interface that simplifies access to complex control functions. Users can monitor and control multiple HVAC units through a uniform web-based interface, eliminating the need to navigate complex proprietary interfaces while maintaining centralized control capabilities.
Solution Approach 2:
The system transitions from local physical interface control to remote web-based control, adding a new dimension of accessibility. Users can access and control HVAC systems from any location with internet connectivity, transforming the operation from on-site manual control to remote digital management, thereby improving ease of operation.
3Ease of operation
If remote access capability is added to HVAC control, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The thermostat performs self-configuration and self-management through its integrated web server. The system automatically handles web protocol communication, data formatting, and interface generation without requiring external control hardware. This self-service capability enables remote access functionality while minimizing the need for additional complex components.

AI summary
An HVAC control system that accommodates and/or facilitates control from a remote location. The HVAC control system may include a web-enabled building control appliance having a controller, a first port and a second port. The controller may implement a web server that is coupled to the first port for serving up one or more web pages on a first network and for receiving a number of responses. The controller may also be coupled to the second port so as to communicate with one or more communicating thermostats via a second network. The web server may be adapted to provide an overview or summary web-page via the first port that displays information regarding the one or more thermostats, where the information that is displayed may be customized for a particular user.
