Abstract
Official abstract text for this publication.
A water heating system includes a plurality of water heaters of which exhaust paths are connected in common to an exhaust path assembly, a control device configured for centralized control of the plurality of water heaters, and a non-volatile storage unit. The plurality of water heaters include control units configured to control hot water supply operations based on communication with the control device, respectively. The storage unit is configured to store information on the water heater of which control unit is recorded to have established communication with the control device. The control device turns off all of the plurality of water heaters when information on the water heater of which control unit has currently established communication with the control device does not match with the information stored in the storage unit.
First claim
Opening claim text (preview).
What is claimed is: 1. A water heating system comprising: a plurality of water heaters of which exhaust paths are connected in common to an exhaust path assembly; a control device configured for centralized control of the plurality of water heaters; and a non-volatile storage unit accessible from the control device, each of the plurality of water heaters including a control unit configured to control a hot water supply operation based on communication with the control device, the non-volatile storage unit being configured to store information on a water heater of which control unit is recorded to have established communication with the control device, and the control device being configured to turn off all of the plurality of water heaters when information on a water heater of which control unit has currently established communication with the control device does not match with the information stored in the non-volatile storage unit; wherein the non-volatile storage unit is configured to store information on the number of water heaters of which control units are recorded to have established communication with the control device, and the control device is configured to turn off all of the plurality of water heaters when the number of water heaters of which control units have currently established communication with the control device is smaller than the number stored in the non-volatile storage unit. 2. The water heating system according to claim 1 , the water heating system further comprising an operation portion configured to accept an external operation instruction, wherein when the operation portion accepts a first operation instruction, the control device is configured to prohibit turn-off of all of the plurality of water heaters based on unmatch of the information on the water heater of which control unit has currently established communication with the control device with the information stored in the non-volatile storage unit. 3. The water heating system according to claim 2 , wherein the control device is configured to cancel prohibition when a prescribed period of time has elapsed since acceptance of the first operation instruction by the operation portion, and when the operation portion accepts a second operation instruction while the control device prohibits turn-off of all of the plurality of water heaters, the control device is further configured to change the prescribed period of time in response to the second operation instruction. 4. The water heating system according to claim 1 , the water heating system further comprising an operation portion configured to accept an external operation instruction, wherein when the operation portion accepts a third operation instruction, the control device is configured to update the information stored in the non-volatile storage unit to the information on the water heater of which control unit has currently established communication with the control device. 5. A water heating system comprising: a plurality of water heaters of which exhaust paths are connected in common to an exhaust path assembly; a control device configured for centralized control of the plurality of water heaters; and a non-volatile storage unit accessible from the control device, each of the plurality of water heaters including a control unit configured to control a hot water supply operation based on communication with the control device, the non-volatile storage unit being configured to store information on a water heater of which control unit is recorded to have established communication with the control device, the control device being configured to turn off all of the plurality of water heaters when information on a water heater of which control unit has currently established communication with the control device does not match with the information stored in the non-volatile storage unit; and an operation portion configured to accept an external operation instruction, wherein when the operation portion accepts a first operation instruction, the control device is configured to prohibit turn-off of all of the plurality of water heaters based on unmatch of the information on the water heater of which control unit has currently established communication with the control device with the information stored in the non-volatile storage unit, and wherein the control device is configured to cancel prohibition when a prescribed period of time has elapsed since acceptance of the first operation instruction by the operation portion, and when the operation portion accepts a second operation instruction while the control device prohibits turn-off of all of the plurality of water heaters, the control device is further configured to change the prescribed period of time in response to the second operation instruction. 6. A water heating system comprising: a plurality of water heaters of which exhaust paths are connected in common to an exhaust path assembly; a control device configured for centralized control of the plurality of water heaters; and a non-volatile storage unit accessible from the control device, each of the plurality of water heaters including a control unit configured to control a hot water supply operation based on communication with the control device, the non-volatile storage unit being configured to store information on a water heater of which control unit is recorded to have established communication with the control device, the control device being configured to turn off all of the plurality of water heaters when information on a water heater of which control unit has currently established communication with the control device does not match with the information stored in the non-volatile storage unit, and an operation portion configured to accept an external operation instruction, wherein the non-volatile storage unit is configured to store information for identifying the water heater of which control unit is recorded to have established communication with the control device, the control device is configured to turn off all of the plurality of water heaters when the water heater of which control unit has currently established communication with the control device does not match with the water heater stored in the non-volatile storage unit, when the operation portion accepts a first operation instruction, the control device is configured to prohibit turn-off of all of the plurality of water heaters based on unmatch of the information on the water heater of which control unit has currently established communication with the control device with the information stored in the non-volatile storage unit, and wherein the control device is configured to cancel prohibition when a prescribed period of time has elapsed since acceptance of the first operation instruction by the operation portion, and when the operation portion accepts a second operation instruction while the control device prohibits turn-off of all of the plurality of water heaters, the control device is further configured to change the prescribed period of time in response to the second operation instruction.
