Information technology -- UPnP Device Architecture -- Part 6-12: Heating, Ventilation, and Air Conditioning Device Control Protocol - Fan Speed Service
This service definition is compliant with the UPnP Device Architecture version 1.0. It defines a service type referred to herein as FanSpeed: 1. FanSpeed: 1 provides programmatic control and status information for air fans used in Heating, Ventilation and Air-Conditioning (HVAC) applications. It allows a control point to command the speed of the fan by means of a continuous 0% to 100% control variable. Fans which are On/ Off or three speed (Off/ Low/ Medium/ High) respond by mapping the continuous control variable to specific vendor-dependent switching points. It provides optional functionality for dual direction reversible fans. FanSpeed: 1 enables the following functions: • Control of the speed of an air-conditioning or ventilation fan. • Reversible fans.
