  • the temperature control device is an air conditioning system. In an alternative embodiment, it is a heater. In a further embodiment, the temperature control device is a refrigerator.
  • the temperature control device has an electronic component that is characterized, for example, by the fact that it has a high inrush current. she For example, it requires significantly more power when switching on than during operation. In this example, the change in operating state would therefore be switching on the electronic component. Alternatively, the change in the operating status is, for example, the increase in a power level. In general, the changes in operating states that lead to a higher energy requirement during or in a certain time after the change are preferably considered.
  • the temperature control device has a control unit that acts on the electronic component. There is also an energy supply interface and a communication interface.
  • the control unit carries out the following steps using the communication interface:
  • An intention signal (a "request signal”, abbreviated: RS) is output, via which the control unit communicates to all other units which receive signals from the temperature control device that a change in the operating state is intended.
  • the control unit listens for signals via the communication interface, receives signals if necessary and evaluates them.
  • the relevant signals each belong to one of two classes: There can be other intentional signals with which the control units of other units, e.g. B. other temperature control devices their intention to change an operating state of an electronic component. However, there can also be change signals (“turning on signal”, TOS for short) from other units, which communicate that an operating state has already been changed. If there is a change signal, then there is already an increased energy requirement in the system, so that the electronic components of the temperature control device should not experience a change in their operating state during this period. If there is an intention signal from another unit, it is relevant whether the other unit has a higher priority than the temperature control device. If this is the case, the other unit has “priority” and can change an operating state first.
  • the temperature control device can first change the operating state of its electronic component. Overall, the control unit waits for a predetermined waiting time (Tw). Then it changes - after the waiting time Tw - the Operating state of the electronic component when there is no change signal and no intention signal from a higher priority entity. In order to signal that this change is taking place and that no other unit should therefore make a change, the control unit sends out its change signal.
  • Tw waiting time
  • the following configurations relate to the reaction of the temperature control device to intention signals and change signals.
  • One embodiment of the temperature control device provides that if there is an intention signal from another unit and the other unit has a higher priority than the temperature control device, the control unit receives and evaluates signals during the waiting time that begins again.
  • the case is dealt with that the control unit receives an intention signal from a unit that has a higher priority than the temperature control device. This is thus a case in which the tempering device has to wait for the other unit. Provision is therefore made for the control unit to start receiving and evaluating signals again, with the entire waiting time starting again from the beginning in this embodiment. Thus, for example, a counter or timer is reset to zero.
  • An alternative or supplementary embodiment of the temperature control device is that, if a change signal is present, the control unit receives and evaluates signals during the waiting time that begins again.
  • another unit is in the process of changing an operating state of an electronic component, that is to say switching it on, for example.
  • the temperature control device starts the waiting time again and receives signals.
  • the other unit thus has at least the waiting time for the change in operating status.
  • This also results in a criterion for measuring the waiting time. In any case, it should be longer than the time during which the increased energy requirement exists for the units or the temperature control device. Or in other words: After the waiting time, the energy requirement of the electronic components in the system in which the temperature control device and the other unit or units are located should be back to a normal level so that the operating state of the electronic component of the Temperature control device can be changed without overloading the power supply.
  • a further embodiment of the temperature control device provides that the control unit outputs the intention signal multiple times. Alternatively, the intention signal is sent continuously. It is thus ensured in both variants that other units or other temperature control devices, which are connected to the temperature control device via a communication channel, receive the intention signal within the waiting time.
  • the control unit in the event that the control unit outputs the change signal via the communication interface, the control unit also stops outputting the intention signal. Thus, if the control unit makes the change in the operating state and issues a change signal in order to announce this, the intention signal is no longer sent.
