Multi-Zone HVAC Control Using Primary and Secondary User Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-zone environmental control systems require users to physically access each zone's control panel to adjust settings, and there is a need for a centralized interface that can receive data from multiple zones and optimize energy use and operation based on individual zone demands.
Innovation Solution
A multi-zone environmental control system that includes a primary user interface for easy access, capable of receiving data from sensors in various zones, processing inputs, and sending control signals to a control module that manages controlled devices across all zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated thermostat is associated with each zone, then each zone can be independently controlled, but the user must physically be in a zone to change temperature setpoints or other settings within that zone
Solution Approach 1:
A remote thermostat acts as an intermediary device that allows users to control any zone's temperature settings from a centralized location. The remote thermostat communicates with the zone control panel via wireless or wired connections, enabling users to adjust setpoints for any zone without physically being present in that zone. This mediator device bridges the gap between user convenience and zone-specific control requirements.
2Ease of manufacture
If the zone control panel is disposed in a central location to facilitate wiring, then system installation is simplified, but the panel is located at a relatively inaccessible location such as in a utility room
Solution Approach 1:
The user interface functionality is extracted from the centrally located zone control panel and placed in a remote thermostat that can be positioned in an accessible location. The zone control panel remains in the utility room for optimal wiring, while the remote thermostat handles all user interactions. This separation allows the control panel to stay in its optimal installation location while providing user-friendly accessibility elsewhere in the building.
3Extent of automation
If software and processing power are disposed within the zone control panel, then the system can process sensor signals, but system setup, testing, and similar actions must be performed at the zone control panel which is located at an inaccessible location
Solution Approach 1:
The remote thermostat serves as an intermediary interface that handles all system configuration, setup, and testing operations. It communicates with the zone control panel's processing systems, allowing users to perform all necessary system operations without accessing the utility room. The zone control panel maintains its processing capabilities while the remote thermostat provides accessible configuration interfaces.

AI summary
A multi-zone environmental control system such as an HVAC and/or an IAQ control system includes a control module, a primary user interface, and at least one secondary user interface. The control module is configured to control an environmental system and controlled devices, each device associated with a respective zone. The primary user interface is in communication with the control mode and associated with a first zone. The primary user interface displays information to the user, receives inputs from the user regarding control of at least the first zone, and transmits signals to the control module, which then controls the device associated with the first zone. Each secondary user interface is associated with a zone other than the first zone and is configured to display information to the user, receive an input from the user concerning control of the respective zone, and communicate with the primary user interface. In turn, the primary user interface transmits signals to the control module, which then controls the devices associated with the respective zones.
