A network of wireless remote climate sensors in a heating, ventilation, and air conditioning (HVAC) system permits the creation of personalized microclimates within an enclosed space. In addition to collecting temperature and humidity data, the wireless remote climate sensors can detect whether the enclosed space is occupied by a human. Human detection is made possible by optional cameras, microphones, and gas sensors on the wireless remote climate sensors. As the human moves throughout the enclosed space, the HVAC system is able to track the human's movement using the wireless remote climate sensors. The HVAC system may adjust airflow to different portions of the enclosed space based on the human's location. The result is an efficient use of system resources to keep users at their ideal temperature.

A control device and a method for controlling a system having at least two fans (1) and/or fan groups for generating a defined setpoint value (VG,setpoint, ΔpG,setpoint), wherein, by changing the operating points of at least one fan (1) depending on which setpoint value is fixedly predetermined, at least one of the fans (1) is brought to an optimal operating point and thereby the efficiency ηG of the system is increased.
