[0019] This example takes the indoor unit address setting of a large-scale central air-conditioning system with 128 indoor units as an example. Generally speaking, the remote control of the indoor unit has a normal control state and a test state. Here we use the test state for setting the address of the indoor unit. Since the change range of the test code is 0-200, it can fully meet the address setting requirements of 128 indoor units. First, send a test code "1" to the first indoor unit, and the indoor unit receives the test code and stores it in a storage unit (such as EEPROM) after parsing, and uses this test code "1" as the address of the indoor unit. Then send the test code "2" to the second indoor unit...until the addresses of 128 indoor units are all set. Thereafter, when the indoor unit is turned on, it first reads the address information in the storage unit and is in a state of waiting to receive. If there is no remote control to receive the signal, the original stor...

The invention relates to a central air conditioning system, in particular to a method for setting the address of an indoor unit of the central air conditioning system. The invention discloses the method for setting the address of the indoor unit of the central air conditioning system, which solves the problems that the mode for setting the address of the indoor unit in the prior art needs to occupy a great deal of chip resources and the on-site setting is inconvenient. The key points of a technical scheme of the method can be summarized in that: a remote controller of the indoor unit is used for sending the only test code to the indoor unit; the indoor unit receives the test code, uses the test code as the address of indoor unit and stores the test code into a storage unit; and hereafter,the indoor unit reads test code information as the address of the indoor unit each time the indoor unit is started up, and if the remote controller sends a new test code, the indoor unit uses the newtest code as the address of the indoor unit and uses the new test code to replace the originally stored test code information. The method has the advantages that: no chip resource is occupied, the on-site setting is convenient, and the method is suitable for setting the address of the indoor unit of a central air conditioner.
Description
technical field [0001] The invention relates to a central air-conditioning system, in particular to a method for setting the address of an indoor unit of the central air-conditioning system. Background technique [0002] The central air-conditioning system is composed of a centralized controller, an outdoor unit controller, and an indoor unit controller (including a wire controller and a remote controller). The indoor unit and outdoor unit feed back to the centralized controller after receiving the signal from the controller to the address to achieve the purpose of data exchange. The centralized controller controls the normal operation of the entire chiller through different control code information, which involves indoor The address setting method of the machine. [0003] The method for setting the address of the indoor unit in the central air-conditioning system in the prior art is: the address control of the indoor unit is determined by the high and low states of the inp...
