Installation method of central air conditioner 485

The central air conditioner 485 is a communication protocol for controlling air conditioning systems in commercial buildings, office buildings and public places. Compared with the traditional control system, the central air conditioner 485 has higher stability and reliability, and can realize faster data transmission and more control functions. The following is the installation method of the central air conditioner 485:

1. Determine the mailing address.

Firstly, it is necessary to determine the communication address of the whole system of central air conditioning, and then set the addresses of various devices to different numbers when installing the central air conditioning 485 network to avoid address conflict.

2. Connect the 485 network transmission line

When installing the central air conditioning 485 network, use two twisted pairs to connect all terminal equipment, such as air conditioning control panel, indoor unit and outdoor unit. Each device should be connected with two twisted pairs, one for transmitting data signals and the other for transmitting ground wires.

3. Set the network parameters

When installing the central air conditioning 485 network, it is necessary to set the network parameters, including baud rate, data bits, check bits and stop bits. The setting of these parameters should be consistent with the specifications of the equipment to ensure the normal work of the network.

test

When installing the central air conditioning 485 network, it is necessary to test whether the network connection is smooth and whether the equipment can communicate normally. You can use professional network testing tools, and you can also judge whether the network is normal by reading the working state of the equipment.

Step 5 Debugging

After the network installation is completed, it needs to be debugged to check whether the system is running normally. Attention should be paid to the running status of each device, data receiving and sending, etc.

In a word, the hardware installation of central air conditioner 485 should be carried out in strict accordance with relevant regulations, and relevant planning should be made before installation to ensure the normal operation of the system and provide convenience for the later period.
