Therefore, when a problem that can be solved by resetting occurs in the heat generating device, it is preferable to reset the heat generating device at that time to solve the problem. On the other hand, when a problem occurs in a heat-utilizing device and the heat-utilizing device enters an error state, unlike the case where a heat-generating device enters an error state, some of the malfunctioning devices become unusable. In many cases, there is no need to recover early from the error state. In addition, if the resolvable problem is such that the heat-utilization equipment can be used continuously, resetting the heat-utilization equipment at the point when it is determined that the problem is resolvable will cause inconvenience to the consumer. It may occur.

This is the number of times the reset process has been performed in cases such as when the reset process was performed to resolve the same resolvable problem. For example, when a resolvable defect occurs and reset processing is executed, the number of consecutive reset processing executions becomes 1. After that, when the resolvable defect is not resolved, reset processing is executed again. The number of consecutive executions of the process is 2, and if the reset process is executed again when the resolvable problem is still not resolved, the number of consecutive executions of the reset process is 3. In other words, in the present embodiment, when a resolvable problem is not resolved even though the reset process is executed again (that is, when the number of consecutive executions of the reset process at this point is 2), the problem occurs. A message is displayed on the display unit 29 to notify that the error has occurred.

Next, an example of the processing flow of the automatic reset system 1 having the above configuration will be described with reference to FIGS. 3 and 4. FIG. In the following description, an example will be described in which the timing signal output unit 33 sends a signal related to the reset timing in advance to each of the reset signal output control units 8c and 16c.

First, the reset timing setting unit 32 sets reset timings for the cogeneration system G1 and the heat source equipment G2, and reset timings for the bathroom dryer G3, the floor heating equipment G4, and the hot water supply equipment G5 (step #1).

Next, the timing signal output section 33 outputs a signal related to reset timing, and the cogeneration side reset signal output control section 8c and the heat source unit side reset signal output control section 16c receive the signal. Then, in the reset signal output control units 8c and 16c, the reset timing for the gas appliances G (the cogeneration system G1, the heat source machine G2, the bathroom dryer G3, the floor heating appliance G4, and the water heater G5) is determined (process # 2).

That is, in the present embodiment, when the gas appliance G in which the resolvable problem has occurred is the cogeneration system G1 or the heat source equipment G2, when the signal indicating that the resolvable problem has been determined is received, Control is performed by the cogeneration-side reset signal output control unit 8c and the heat source unit-side reset signal output control unit 16c so that the reset signal is output from the cogeneration-side reset signal output unit 8b and the heat source unit-side reset signal output unit 16b. become. On the other hand, if the gas appliance G in which the resolvable defect has occurred is the bathroom dryer G3, the floor heating appliance G4, or the hot water supply appliance G5, the reset signal output unit on the heat source machine side will be reset at the predetermined time when these appliances will not be used. Control by the heat source machine side reset signal output control section 16c is performed so that the reset signal is output from 16b.

Next, when the cogeneration-side control unit 6 or the heat source unit-side control unit 14 detects a problem with the gas appliance G, a signal indicating the content of the problem (for example, a signal indicating an error code) is sent to the control device 30. Then, the failure type determination unit 31 determines the gas appliance G that is the target of the detected failure (step #3), and if the gas appliance G is the cogeneration system G1 or the heat source equipment G2 (step #3 : heat generator), proceed to step #4. On the other hand, if the gas appliance G is the bathroom dryer G3, the floor heating appliance G4, or the hot water supply appliance G5 (step #3: heat utilization appliance), the process proceeds to step #8.

In step #4, similarly, the defect type determination unit 31 determines whether or not the detected defect is a defect that can be resolved by resetting the cogeneration system G1 or the heat source machine G2. If so (step #4: Yes), a signal to that effect is sent to the cogeneration side reset signal output control section 8c or the heat source unit side reset signal output control section 16c (step #5). Next, the cogeneration side reset signal output section 8b and the heat source machine side reset signal output section 16b are controlled by the reset signal output control sections 8c and 16c to output reset signals (step #6). Then, reset processing of the cogeneration system G1 by the cogeneration-side reset execution unit 8a and reset processing of the heat source unit G2 by the heat source unit-side reset execution unit 16a are executed (step #7). Thereby, the cogeneration system G1 or the heat source machine G2 is reset. After the reset process is executed, the process moves to step #14. On the other hand, when it is determined that the detected defect is not a resolvable defect (step #4: No), a signal to that effect is sent to the notification processing unit 27 (step #13), and the notification processing unit 27 A defect display process is executed (step #17). As a result, the display unit 29 displays an indication that a problem has occurred in the cogeneration system G1 or the heat source machine G2.

In step #8, it is determined whether or not the detected problem is a problem that can be resolved by resetting the bathroom dryer G3, the floor heating device G4, or the water heater G5 in the problem type determination unit 31. If it is determined that there is (step #8: Yes), a signal to that effect is sent to the heat source machine side reset signal output control section 16c (step #9). Next, the heat source machine side reset signal output control unit 16c determines whether or not the reset timing has come (that is, whether or not the predetermined time has come) (step #10), and if it is determined that the reset timing has come ( If step #10: Yes), the process moves to step #11, and if it is determined that the reset timing has not come (step #10: No), step #10 is repeated. Then, the heat source machine side reset signal output section 16b is controlled to output a reset signal instructing resetting of the device in which the malfunction has occurred (step #11), and the heat source machine side reset execution section 16a executes the device reset processing. (Step #12). As a result, the malfunctioning device is reset. After the reset process is executed, the process moves to step #14. On the other hand, when it is determined that the detected defect is not a resolvable defect (step #8: No), a signal to that effect is sent to the notification processing unit 27 (step #13), and the notification processing unit 27 A defect display process is executed (step #17). As a result, the display section 29 displays an indication that the bathroom dryer G3, the floor heating device G4, or the hot water supply device G5 has malfunctioned.

In step #14, it is determined whether or not a problem is detected in the cogeneration-side control unit 6 or the heat source unit-side control unit 14, and if no problem is detected (step #14: No), the process ends. do. On the other hand, if the defect is still detected (step #14: Yes), the defect type determination unit 31 determines whether or not the reset processing has been continuously executed less than twice (step #15). If it is less than two times (step #15: Yes), the process returns to step #3. (process #16), and the defect display process is executed by the notification processing unit 27 (process #17).

As described above, according to the automatic reset system for gas appliances according to the present embodiment, when a problem occurring in a gas appliance G is a problem that can be resolved by resetting the gas appliance G, the gas appliance G is automatically reset. is automatically reset, and the malfunction of the gas appliance G is resolved.
