Solution Overview

Problem

Current HVAC controllers face challenges in efficiently controlling zoned HVAC systems, particularly in the commissioning process, where enrolling wireless devices into specific zones is cumbersome and lacks user-friendly interfaces for effective zone management.

Innovation Solution

An HVAC controller with a user interface that allows for commissioning mode operation, enabling users to enroll wireless devices into designated zones through accessible inputs, and a portable power supply for flexibility during installation, facilitating zone-by-zone enrollment and control of zoned HVAC systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional HVAC controller is used for commissioning, then the controller can control HVAC components, but the process of enrolling wireless devices into zones is cumbersome and lacks user-friendly interfaces

Engineering Contradiction:
Improveease of enrolling wireless devicesVSAvoidcomplexity of commissioning process
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The commissioning process is segmented into distinct operational modes (commissioning mode vs. normal operation mode), allowing the controller to present different interfaces and functionalities appropriate to each phase. During commissioning mode, the controller specifically enables wireless device enrollment with simplified zone assignment, separating this complex task from the overall system operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller acts as an intermediary between wireless devices and the HVAC system during commissioning. It provides a dedicated enrollment interface that mediates the pairing process, automatically handling device discovery, authentication, and zone assignment, thereby simplifying what would otherwise be a complex manual configuration process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the HVAC controller is mounted on a wall plate with fixed electrical connections, then stable power and control are provided, but flexibility during installation and commissioning is reduced

Engineering Contradiction:
Improveflexibility during installationVSAvoidstability of electrical connections
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system transitions from a static, permanently mounted installation to a dynamic commissioning process. The controller can be temporarily positioned and powered during commissioning, then permanently mounted afterward. This dynamic approach allows the installation process to adapt to different commissioning scenarios while maintaining reliable connections once installed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Wireless devices are enrolled into zones during the commissioning phase before final installation and permanent mounting. This preliminary action of configuring the system while portable allows for flexible setup, and once commissioning is complete, the controller is permanently mounted to provide stable, reliable operation.

Inventive Principle:
Principle #10Preliminary action

AI summary

An HVAC controller may have an operational mode in which the HVAC controller provides operational instructions, and a commissioning mode in which a plurality of wireless devices can be enrolled. While in the commissioning mode, the HVAC controller is configured to accept a first input from a user via the user interface that designates a first zone of the plurality of zones and causes each of two or more first wireless devices that are subsequently placed in an enrollment mode by the user to be enrolled in the first zone, and to subsequently accept a second input from the user via the user interface that designates a second zone of the plurality of zones and causes each of two or more second wireless devices that are subsequently placed in an enrollment mode by the user to be enrolled in the second zone.
