Systems and methods for identifying an installation location of a thermostat device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermostat systems in hotels and multiple dwelling units face challenges in accurately assigning thermostats to specific rooms, especially when thermostats are replaced, leading to potential errors in temperature control and data accuracy.
Innovation Solution
The proposed solution involves assigning room numbers and system configurations to a subbase assembly, which communicates this information to the thermostat when connected, thereby automatically updating the database and ensuring correct thermostat assignment without the need for manual reprogramming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a thermostat is replaced with a new unit having a different identifier (e.g., MAC ID), then the thermostat can be updated to improve system functionality, but the database must be manually reprogrammed to reassign the correct room identifier, increasing loss of time and potential for error
Solution Approach 1:
The subbase assembly automatically performs the assignment function that previously required manual intervention. When a thermostat is installed on the subbase, the subbase's processor automatically reads the thermostat's identifier and assigns the corresponding room identifier from stored mappings, eliminating the need for manual database reprogramming and reducing errors in thermostat assignment
Solution Approach 2:
The system pre-stores multiple thermostat identifiers and their corresponding room identifiers in the subbase's memory before any replacement occurs. This preliminary preparation allows the automatic assignment to function seamlessly when a thermostat is replaced, as the mapping data is already available and does not require real-time manual input
2Reliability
If manual reprogramming is performed to update thermostat identifiers in the database, then the correct room assignment can be maintained, but the complexity of the replacement process increases and human error may occur
Solution Approach 1:
The subbase assembly autonomously handles the entire identifier assignment process without requiring manual database access or reprogramming. The processor automatically reads the new thermostat's identifier, retrieves the corresponding room identifier from stored mappings, and completes the assignment, thereby maintaining data accuracy while eliminating the complexity of manual procedures
Solution Approach 2:
The subbase acts as an intermediary device between the thermostat and the central database system. It stores local mappings of thermostat identifiers to room identifiers and performs the assignment function locally, serving as a mediator that eliminates the need for direct manual intervention in the database while ensuring accurate data assignment

AI summary
A heating and/or cooling equipment (HVAC) control system includes a subbase a thermostat releasably engageable with the subbase. An encoder is physically associated with the subbase. The provides information to the thermostat when the thermostat is coupled to the subbase. The information at least uniquely identifies the thermostat to a centralized HVAC system provided to control HVAC related functionalities in each of a plurality of rooms in a building.
