ISO/IEC 29341-6-11:2008

Overview

ISO/IEC 29341-6-11:2008 - "Information technology - UPnP Device Architecture - Part 6-11: Heating, Ventilation and Air Conditioning Device Control Protocol - Fan Operating Mode Service" defines a UPnP-compliant service template for controlling and reading the user operating modes of a forced-air HVAC system. It is part of the ISO/IEC 29341 series that maps UPnP Device Architecture v1.0 into an international standard for peer-to-peer connectivity of appliances, wireless devices and PCs in homes, small businesses and public spaces.

Key details:

• Conforms to UPnP Device Architecture 1.0
• Service type (URN): urn:schemas-upnp-org:service:HVAC_FanOperatingMode:1
• Purpose: change and read fan operating modes for forced-air HVAC systems
• Includes XML service description, eventing model and test definitions

Key Topics

• Service modeling and state variables
  • Standard state variables include Mode, FanStatus, and Name.
  • Example Mode allowed values defined: Auto, ContinuousOn, PeriodicOn.
• Control actions
  • Core actions specified: SetMode, GetMode, GetFanStatus, GetName, SetName.
  • Action argument lists and relationships between actions are defined so UPnP control points can interact predictably.
• Eventing and moderation
  • Defines how state changes are evented to subscribers and how moderation of event traffic is handled.
• XML service description and testing
  • Provides the XML schema for service description and includes test cases to validate interoperability and correct behavior.

Applications

This standard is practical for:

• HVAC equipment manufacturers implementing UPnP-enabled fan control in forced-air units
• Smart home platform developers integrating HVAC fan mode control into automation and voice assistants
• Building automation integrators requiring standardized device behavior for multi-vendor deployments
• Firmware and IoT device engineers who implement UPnP services and need a structured XML service description, events and test cases

Benefits:

• Enables interoperable fan mode control across devices and control points
• Simplifies integration into ad-hoc and unmanaged networks (home/small business/public)
• Supports event-driven monitoring and remote control of fan operating modes

Related Standards

Part of the ISO/IEC 29341 (UPnP) family. Relevant companion parts include:

• ISO/IEC 29341-6-1 (HVAC_System:1 Device)
• ISO/IEC 29341-6-2 (HVAC_ZoneThermostat)
• ISO/IEC 29341-6-12 (UPnP FanSpeed Service)
• ISO/IEC 29341-6-17 (HVAC_UserOperatingMode Service)

Using ISO/IEC 29341-6-11:2008 helps ensure standardized, interoperable fan-mode control in UPnP-based HVAC deployments and simplifies integration across smart home and building automation ecosystems.
