Method for the temperature control of a component in which a temperature-control system is provided, comprising: a) a temperature-control device designed for heating or cooling a temperature-control fluid; b) at least two, i.e. (n≥2) temperature-control assemblies (5, 5') which are designed for passing the temperature-control fluid through a component to be temperature-controlled and which are connected to the temperature-control device via (n≥2) individual feed line parts (6', 6") and via (n≥2) individual return line parts (7', 7"), wherein each of the (n≥2) individual return line parts (7', 7") comprises its own return flow temperature sensor (8, 8') for measuring the individual return flow temperature of the temperature-control fluid from the corresponding temperature-control assembly (5, 5'); and c) a controller, which comprises valves (10, 10') having actuators (11, 11') which are arranged in the (n≥2) individual feed line parts (6', 6") or (n≥2) return line parts (7', 7") and which are designed for setting an opening degree of the respectively associated valve (10, 10'), wherein the controller is designed for actuating the actuators (11, 11') and for reading the return flow temperature sensors (8, 8') and comprises a room temperature sensor for detecting and reporting an ACTUAL temperature in an immediate vicinity of the component; wherein the temperature-control method is characterized in that: i) the use of feed flow temperature sensors is omitted; ii) a TARGET temperature is predetermined for the immediate vicinity of the component; iii) a first temperature window not including the predetermined TARGET temperature is defined as a first positive temperature difference (ΔT 1) for cooling the component or as a first negative temperature difference (ΔT 2) for heating the component to the predetermined TARGET temperature and is implemented in the controller; and iv) the controller, when the ACTUAL temperature reported by the room temperature sensor enters the first temperature window as a result of a change in temperature, issues to the actuators of [1 to (n-1)] temperature-control assemblies, whose return flow temperature precedes the return flow temperatures of the other [1 to (n-1)] temperature-control assemblies in the direction of the current change in temperature, the command to close the valve for a first closing time (t 1), wherein the controller issues the command to the actuators of the other [1 to (n-1)] temperature-control assemblies to keep the valves open during the first closing time (t 1). a) a temperature-control device designed for heating or cooling a temperature-control fluid; b) at least two, i.e. (n≥2) temperature-control assemblies (5, 5') which are designed for passing the temperature-control fluid through a component to be temperature-controlled and which are connected to the temperature-control device via (n≥2) individual feed line parts (6', 6") and via (n≥2) individual return line parts (7', 7"), wherein each of the (n≥2) individual return line parts (7', 7") comprises its own return flow temperature sensor (8, 8') for measuring the individual return flow temperature of the temperature-control fluid from the corresponding temperature-control assembly (5, 5'); and c) a controller, which comprises valves (10, 10') having actuators (11, 11') which are arranged in the (n≥2) individual feed line parts (6', 6") or (n≥2) return line parts (7', 7") and which are designed for setting an opening degree of the respectively associated valve (10, 10'), wherein the controller is designed for actuating the actuators (11, 11') and for reading the return flow temperature sensors (8, 8') and comprises a room temperature sensor for detecting and reporting an ACTUAL temperature in an immediate vicinity of the component; i) the use of feed flow temperature sensors is omitted; ii) a TARGET temperature is predetermined for the immediate vicinity of the component; iii) a first temperature window not including the predetermined TARGET temperature is defined as a first positive temperature difference (ΔT 1) for cooling the component or as a first negative temperature difference (ΔT 2) for heating the component to the predetermined TARGET temperature and is implemented in the controller; and iv) the controller, when the ACTUAL temperature reported by the room temperature sensor enters the first temperature window as a result of a change in temperature, issues to the actuators of [1 to (n-1)] temperature-control assemblies, whose return flow temperature precedes the return flow temperatures of the other [1 to (n-1)] temperature-control assemblies in the direction of the current change in temperature, the command to close the valve for a first closing time (t 1), wherein the controller issues the command to the actuators of the other [1 to (n-1)] temperature-control assemblies to keep the valves open during the first closing time (t 1).
