Abstract
Official abstract text for this publication.
A controller includes a first storage storing setting information used for operation control of a heat exchange system that exchanges heat between fluid and a heat medium. The controller executes operation control using the setting information. A communicator includes a second storage medium storing setting information used for the operation control, the communicator communicates with external equipment, the controller and the communicator are mounted on an identical outdoor unit, an identical indoor unit, or an identical central control panel. The controller and the communicator execute synchronization processing between the setting information stored in the first storage and the setting information stored in the second storage, and in a case where the setting information stored in the second storage has been changed in response to a request from the external equipment, the communicator transmits the changed setting information to the controller in the synchronization processing.
First claim
Opening claim text (preview).
What is claimed is: 1 . A control device comprising: a controller including a first storage medium configured to store setting information used for operation control of a heat exchange system configured to exchange heat between fluid and a heat medium, the controller being configured to execute the operation control by use of the setting information; and a communicator including a second storage medium configured to store setting information used for the operation control, the communicator being configured to communicate with external equipment, wherein the controller and the communicator are mounted on an identical outdoor unit, an identical indoor unit, or an identical central control panel, the controller and the communicator execute synchronization processing between the setting information stored in the first storage medium and the setting information stored in the second storage medium, and in a case where the setting information stored in the second storage medium has been changed in response to a request from the external equipment, the communicator transmits the changed setting information to the controller in the synchronization processing, wherein: the communicator transmits the setting information stored in the second storage medium to the controller in response to power-on of the heat exchange system, the controller determines whether or not the setting information stored in the first storage medium and the setting information received from the communicator are different from each other, and in a case where the setting information stored in the first storage medium and the setting information received from the communicator are different from each other, sets the setting information received from the communicator as setting information used for the operation control of the heat exchange system, and the controller includes one or more switches capable of setting setting information used for the operation control, and in a case where it is determined that the setting information stored in the first storage medium and the setting information received from the communicator are identical to each other, determines whether or not the setting information stored in the first storage medium and the setting information set by the one or more switches are different from each other, and in a case where the setting information stored in the first storage medium and the setting information set by the one or more switches are different from each other, sets the setting information set by the one or more switches, as the setting information used for the operation control of the heat exchange system. 2 . The control device according to claim 1 , wherein the communicator determines whether or not the communicator is communicable with the controller, and in a case where it is determined as communicable, transmits the setting information stored in the second storage medium to the controller. 3 . The control device according to claim 1 , wherein the controller determines, based on specific information in the setting information received from the communicator, whether or not the setting information received from the communicator is set as setting information used for the operation control of the heat exchange system, and in a case where it is determined as the setting information being not set, sets the setting information stored in the first storage medium as the setting information used for the operation control of the heat exchange system. 4 . The control device according to claim 1 , wherein the controller and the communicator execute the synchronization processing, in a case where the setting information in any of the controller and the communicator has been changed, or at a certain time interval. 5 . A heat exchange system comprising: the control device according to claim 1 , wherein the heat exchange system is configured to exchange heat between fluid and a heat medium, and operation of the heat exchange system is controlled by the control device. 6 . A control device comprising: a controller including a first storage medium configured to store setting information used for operation control of a heat exchange system configured to exchange heat between fluid and a heat medium, the controller being configured to execute the operation control by use of the setting information; and a communicator including a second storage medium configured to store setting information used for the operation control, the communicator being configured to communicate with external equipment, wherein the controller and the communicator execute synchronization processing between the setting information stored in the first storage medium and the setting information stored in the second storage medium, and in the synchronization processing, the setting information stored in the first storage medium is transmitted at least from the first storage medium of the controller to the second storage medium of the communicator, and in a case where the setting information stored in the second storage medium has been changed in response to a request from the external equipment, the communicator transmits the changed setting information to the controller in the synchronization processing, wherein: the communicator transmits the setting information stored in the second storage medium to the controller in response to power-on of the heat exchange system, the controller determines whether or not the setting information stored in the first storage medium and the setting information received from the communicator are different from each other, and in a case where the setting information stored in the first storage medium and the setting information received from the communicator are different from each other, sets the setting information received from the communicator as setting information used for the operation control of the heat exchange system, and the controller includes one or more switches capable of setting setting information used for the operation control, and in a case where it is determined that the setting information stored in the first storage medium and the setting information received from the communicator are identical to each other, determines whether or not the setting information stored in the first storage medium and the setting information set by the one or more switches are different from each other, and in a case where the setting information stored in the first storage medium and the setting information set by the one or more switches are different from each other, sets the setting information set by the one or more switches, as the setting information used for the operation control of the heat exchange system. 7 . The control device according to claim 6 , wherein the communicator determines whether or not the communicator is communicable with the controller, and in a case where it is determined as communicable, transmits the setting information stored in the second storage medium to the controller. 8 . The control device according to claim 6 , wherein the controller determines, based on specific information in the setting information received from the communicator, whether or not the setting information received from the communicator is set as setting information used for the operation control of the heat exchange system, and in a case where it is determined as the setting information being not set, sets the setting information stored in the first storage medium as the setting information used for the operation control of the heat exchange system. 9 . The control device according to claim 6 , wherein the controller and the communicator execute the synchronization processing, in a case where the setting inf
