Heating and cooling system.

Recently, many technologies using an automatic control system have been provided in everyday life, so that the convenience of life can be provided.

In recent years, as the number of high-rise buildings such as buildings and apartments has increased, an automatic control system is essential for managing facilities such as heating and cooling devices in such buildings.

Conventionally, in such an automatic control system, a plurality of cooling and heating units can be controlled by a single terminal (PC or the like) by wire during building construction.

Conventionally, a control system is configured for each individual space so that the cooling / heating supply pipe is opened and closed by the operation of the control system so that supply of cooling and heating is blocked even when a person is absent.

However, such a control system is not practical because the operator or the worker must go directly to the corresponding position to operate the control system.

In other words, when the worker or the worker goes to work, the supply of the cooling / heating is continued unless the control system is operated. Therefore, the building manager who is in charge visits the respective individual spaces directly and operates the control system manually, Therefore, troublesome work has been caused due to this, and in case of wired communication, many problems have arisen due to the limitation of the installation space and the increase of the construction cost.

On the other hand, Korean Patent Registration No. 10-1365167 entitled " Cooling and Air-Handling Unit Control Module and Its Control Method "(Date Apr. 23, 2014) discloses a control module for system control and a control method thereof.

This is because, in the central control method, the ID setting of each device is manually operated by the field installer on the main control board built in the main body, and ID is assigned to each device. Because of the need to disassemble the equipment that has already been installed, there are many difficulties in setting up the system, such as difficulty in setting, excessive setting time, etc. If the ID needs to be changed after installation, There were many difficult parts to work such as disassembly.

As described above, in the conventional cooling / heating system, when the structure of each room in a building is changed or expanded / contracted, a plurality of cooling / heating devices are added or changed. In this case, .
