Abstract: A method of training a comfort model used for controlling a heating, ventilation, and air-conditioning, HVAC, system. The method includes: a user device providing a plurality of user feedbacks, each of the plurality of user feedbacks is provided at a respective point in time and describes a thermal comfort of a user using the user device; at each point in time associated with the plurality of user feedbacks, each of a plurality of HVAC devices detecting running parameters; and for each of the plurality of user feedbacks: inputting the running parameters of each of the plurality of HVAC devices detected at the respective point in time into the comfort model to generate a predicted thermal comfort, determining a loss value by comparing the predicted thermal comfort with the thermal comfort described by the respective user feedback, and training the comfort model to reduce the loss value.

Abstract: A heating, ventilation, and air-conditioning, HVAC, system and a method of controlling a HVAC system, The method includes: successively for at least two HVAC devices of a plurality of HVAC devices: controlling the HVAC device in accordance with a set target temperature value which is different from an environmental temperature value, wherein the other HVAC devices of the plurality of HVAC devices are deactivated or running with unvarying running parameters, and for at least two environmental sensors of a plurality of environmental sensors, determining whether environmental parameters detected by the environmental sensor change; correlating at least one environmental sensor to the HVAC devices for which a change of the environmental parameters is determined; and controlling the HVAC system to change at least one environmental parameter associated with the at least one environmental sensor using the HVAC devices correlated with the at least one environmental sensor.
