By the way, recently, the development cycle of gas appliances has been accelerated, new products and improved products have been on the market one after another, and the function of gas appliances has increased due to the adoption of electrical control, which has become complicated. . For this reason, the method of repairing or commissioning a gas appliance after construction is different depending on the model of the gas appliance, and even the same model is different for each function and is complicated.

Conventionally, a repair / construction worker manually conducts a test operation of gas equipment while referring to a manual or the like.
There was a risk that the repair / construction worker would make a mistake in the trial run method, or forget to perform the trial run for a function that requires operation confirmation. In this case, there is a possibility that the operator may mistakenly consider that the repair or construction is completed without the failure repair or construction being complete, or may miss the repair mistake or construction mistake of the gas equipment.

The present invention has been made in view of the above points, and when a repair / construction worker carries out a trial run after repairing or constructing a gas appliance, there is a possibility that the trial run method may be wrong or the operation check needs to be performed. It is an object of the present invention to provide a repair construction support system for gas equipment, which can eliminate the possibility of forgetting to perform a trial operation of functions.

[0007]

In order to achieve the above-mentioned object, the present invention comprises a repair and construction support system for a gas appliance having a terminal device for performing a trial run of the gas appliance by communicating with the gas appliance. did.

Further, according to the present invention, the terminal device has a function of communicating with a host computer, and the terminal device receives information necessary for the test operation from the host computer.

[0009]

With the above-described structure, the present invention enables the gas equipment and the terminal device to communicate with each other and perform a test run of the gas equipment based on a command from the terminal equipment.

The terminal device can receive the information necessary for the trial run of the gas equipment, that is, the trial run program and the like from the host computer.
