ISO/IEC 29341-6-14:2008 Overview
ISO/IEC 29341-6-14:2008, titled Information technology - UPnP Device Architecture - Part 6-14: Heating, Ventilation, and Air Conditioning Device Control Protocol - Setpoint Schedule Service, is an international standard developed by the International Electrotechnical Commission (IEC). It defines a service protocol within the Universal Plug and Play (UPnP) Device Architecture tailored specifically for HVAC (Heating, Ventilation, and Air Conditioning) setpoint schedules.
This standard facilitates communication and control of HVAC systems by describing variables and actions related to timed temperature setpoints, thus enabling flexible, standards-based connectivity and interoperability of intelligent HVAC appliances within homes, offices, and public spaces. It is particularly suited for ad-hoc and unmanaged network environments, supporting pervasive peer-to-peer networked devices.
Key Topics and Features
-
Setpoint Schedule Variables
The standard defines key state variables to manage HVAC schedules, including:
- Day of Week (A_ARG_TYPE_DayOfWeek): Specifies the day associated with scheduled events.
- Event Name (A_ARG_TYPE_EventName): Identifies named events for which schedules apply, such as "morning warmup".
- Start Time (A_ARG_TYPE_StartTime): Indicates when a scheduled temperature change begins.
- Heating Setpoint (A_ARG_TYPE_HeatingSetpoint): Temperature setting for heating during an event.
- Cooling Setpoint (A_ARG_TYPE_CoolingSetpoint): Temperature setting for cooling.
- EventsPerDay: A delimited string outlining all scheduled setpoint changes for a specific day.
-
Core Actions
The protocol defines key control interactions to manage setpoint schedules:
- SetEventParameters: Create or update scheduled events with relevant parameters (time, setpoints, event name).
- GetEventsPerDay: Retrieve a list of scheduled temperature setpoint events for a specified day.
-
Service Compliance and Identification
Utilizes the UPnP Service Type identifier:
URN:SCHEMAS-UPNP-ORG:SERVICE:HVAC_SETPOINTSCHEDULE:1
-
Eventing and Moderation
Supports event notifications to subscribe clients when setpoint schedules change, enabling responsive HVAC control systems.
Practical Applications
ISO/IEC 29341-6-14:2008 serves as a foundation for smart HVAC systems in residential, commercial, and public environments. Key applications include:
-
Smart Home Automation:
Enables programmable HVAC temperature settings based on daily routines, improving energy efficiency and occupant comfort.
-
Commercial Building Management:
Facilitates centralized control of HVAC schedules across multiple zones or rooms, optimizing resource use and maintenance.
-
IoT HVAC Devices:
Supports seamless integration of HVAC thermostats and sensors into IoT ecosystems allowing peer-to-peer communication without centralized control.
-
Public Spaces and Small Businesses:
Allows flexible HVAC scheduling that adapts to opening hours and occupancy patterns to reduce operational costs.
