DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic test equipment for a hot water heating apparatus having a heat source device and one or more terminal radiators receiving hot water from the heat source device.

[0002]

2. Description of the Related Art Conventionally, there has been provided a hot water heating apparatus provided with a heat source device and one or more terminal radiators for receiving circulation of hot water from the heat source device. In such a conventional heating device, it is usually necessary to perform a test operation after installation and check whether terminals such as a heat source device and a terminal radiator work normally. In an apparatus having an automatic test operation mode for automatically performing the test operation in addition to the normal operation mode, the operation is normally performed by switching between the automatic test operation mode and the normal operation mode.

[0003]

However, in the hot water heating apparatus which can be operated by switching between the automatic test operation mode and the normal operation mode as described above, when the automatic test operation switch is turned on, the normal operation is usually performed. The operation mode does not work, so that the command relating to the normal operation from the remote controller is not accepted by the main controller. For this reason, for example, by turning on the automatic test run switch, all the test run display lamps of each terminal are turned on, and when it is determined that each terminal is normal, the test run display lamp corresponding to the terminal is turned off. In the device, when all terminals are judged to be normal, all test run indicator lamps are turned off, and thereafter, it is possible to easily identify whether the operation mode is the automatic test run mode or the normal operation mode. There is a problem in that a construction worker or the like cannot operate the remote controller or the like by misunderstanding the test operation mode but the normal operation mode, and thus has a problem that the apparatus is determined to be faulty .

Accordingly, the present invention solves the above-mentioned drawbacks of the conventional automatic test operation of a hot water heating apparatus, makes it easy to distinguish between the automatic test operation mode and the normal operation mode, and leaves the automatic test operation mode unreleased. It is an object of the present invention to provide an automatic test operation method of a hot water heating device without any trouble .

[0005]

In order to achieve the above object, an automatic test running method for a hot water heating apparatus according to the present invention comprises a heat source unit, one or a plurality of terminal radiators receiving hot water from the heat source unit. An automatic test operation mode having at least a main controller for performing control of each unit by two-way communication, and checking whether each terminal of the heat source device or the terminal radiator is normal in addition to the normal operation mode as an operation mode. When the automatic test run switch is turned on, first, all the test run display lamps of each terminal provided in the main controller are turned on, and then the check operation of each terminal is sequentially performed, and these terminals are normally operated. If so, turn off the corresponding test run indicator lamp and, if it is not normal, turn the corresponding test run indicator lamp on and off. The method, when it is determined that all of the terminals are normal, the operation mode is automatically switched to the normal operation mode even if the automatic test run switch is not turned off, and otherwise are that automatic commissioning switch even if all checks are completed was prevented switched operation mode unless turned off in the normal operation mode and feature.

[0006]

SUMMARY OF] According to features of the present invention, the automatic commissioning switch is turned on, first commissioning display lamp provided corresponding to each terminal is turned on the main controller. Then, a test operation check of each terminal is sequentially performed. If the test operation is normal, the lit test operation display lamp of the terminal is turned off. If it is not normal, the lit test run indicator lamp of the terminal blinks. Unless the automatic test run switch is turned off in the middle, the check is performed until all the terminals are checked.If all the terminals are normal, the automatic test run mode is automatically switched to the normal operation mode at that time. Be replaced. On the other hand, if any terminal has a failure, the operation mode is not switched to the normal operation mode unless the automatic test run switch is turned off, so that the failure display in the blinking state is continuously displayed. When all terminals are normal, the operation mode is automatically switched to the normal operation mode, so that the tester such as a constructor can perform operations in the normal operation mode without any special attention. it can. In addition, since the terminal is not left in the automatic test mode with the test operation indicator lamps of all terminals turned off, the user or the like may misunderstand the normal operation mode and cannot operate the remote control etc. Will be resolved. Further, if any terminal has a failure, the operation mode is not automatically switched, so that the user can surely know that the terminal has a failure .

Next, an embodiment of an automatic test running method of the apparatus performed by the main controller 50 according to a predetermined program will be described with reference to FIG. In the flow shown in FIG. 2, the water is now in the hot water storage tank 11 with the high water level switch 11a.
When the automatic test run switch 56 of the main controller 50 is turned on while the water level is at the ON level (S
11), the main controller 50 first switches the entire apparatus, such as the heat source device 10 and the terminals of the terminal radiators 41 to 44, to the automatic test operation mode (S12), and turns on the test operation display lamps 51 to 55 of the main controller 50. All are lit (S13). Next, the main controller 50
A check is sequentially started for each terminal of the heat source device 10 and each of the terminal radiators 41 to 44 to determine whether or not it is normal (S1).
4). In the check, if the checked terminal is normal in the check (Yes in S15), the main controller 50 turns off one of the corresponding test run display lamps 51 to 55. If the checked terminal is not normal, that is, if the terminal is out of order (NO in S15), one of the corresponding test run display lamps 51 to 55 is turned on and off. That is, for example, when the heat source device 10 is checked and the heat source device 10 is normal (Yes in S15), the test run indicator lamp 55 is turned off (S16), and the failure (S15
If NO), the test run display lamp 55 is made to blink (S17). Similarly, when the first terminal radiator 41 is checked, if the radiator 41 is normal (Yes in S15), the test run indicator lamp 51 is turned off (S1).
6) If failure (NO in S15), the test run indicator lamp 51 is made to blink (S17).

The main controller 50 determines whether or not all the terminals are normal at each time when one terminal is checked (S18), and when all the terminals are normal (Yes in S18). , The operation mode is automatically switched to the normal operation mode (S21), and the operation is terminated. In this case, all the trial run display lamps 5
Since steps 1 to 55 are turned off, step S
Not through 22. In step S18, other than the case where all the terminals are normal (including the case where all the terminals have been checked but some of them are not normal and the case where all the terminals have not been checked yet) (No in S18), the automatic test run switch 56
Unless is turned off (NO in S19), the process further proceeds to step S20 to determine whether or not all terminals have been checked. If not (NO in S20), the process returns to step S14 and returns to step S14. Check the terminal. Even if it is determined in step S20 that all the checks have been completed, in this case, since any terminal has a failure, the main controller 50 ends the automatic test run mode unless the automatic test run switch 56 is turned off. do not do. When the automatic test run switch 56 is turned off (Yes in S19), the main controller 50 switches the operation mode to the normal operation mode and turns off all the test run display lamps (the flashing test run display lamps) (S2).
2). Of course, even during the automatic test operation, if the automatic test operation switch 56 is turned off, the operation mode is switched to the normal operation mode, and all the test operation display lamps 5 are turned on.
1 to 55 are turned off (S22), and the operation ends. According to the driving method as described above, when all the terminals are normal, all the test operation display lamps 51 to 55 are turned off, and the operation becomes the same as in the normal operation mode. At the same time, since the operation mode is automatically switched to the normal operation mode, it is possible to prevent the operation mode from being left in the automatic test operation mode. If the operation mode is left as it is in the automatic test operation mode, the operation with the remote controller 70 becomes impossible, so that the device may be mistaken as a failure.

[0014] In the above embodiments, a preliminary check of the presence or absence of failure in each terminal controller 61-64 and the communication line can be performed in the first prior to or automatic commissioning in the automatic commissioning . In this case, for example, the communication lines from the terminal controllers 61 to 64 are connected to the connectors of the main controller 50, and the automatic test run switch 56 is turned on to check whether any of the test run display lamps 51 to 54 is lit. See if it is. If there is a lamp 51 to 54 that does not light, the communication line is disconnected from the connector corresponding to the lamp 51 to 54, and the connector is short-circuited. When the corresponding test run display lamps 51 to 54 are turned on by this short circuit, it is possible to easily know that there is a failure such as a disconnection on the communication line or the terminal radiators 41 to 44 side.

[0015]

According to the present invention, there is provided the above construction.
According to the automatic test operation method of the hot water heating apparatus described in the above, when the automatic test operation switch is turned on, first, all the test operation display lamps of each terminal provided in the main controller are turned on, and then the check operation of each terminal In order to turn off the corresponding test run display lamp if those terminals are normal and to blink the corresponding test run display lamp if not normal, where all of the terminals are normal. If it is determined that there is, the operation mode is automatically switched to the normal operation mode even if the automatic test operation switch is not turned off. It is no longer possible for the system to be left unattended, so the test operator, such as a constructor, mistakes the automatic test operation mode for the normal operation mode. Or, also possible to prevent a accidentally to be faulty to not be operated such as a remote controller at that for the automatic commissioning mode. If any of the terminals has a failure, the operation mode is not automatically switched from the automatic test operation mode to the normal operation mode. You can know .
