Specifically, the energy-saving setting command includes the communication address of the air-conditioning indoor unit C (same as the indoor unit C shown in FIG. 1 ), and the energy-saving temperature range.

Open the monitoring system in the host computer A, start the energy saving setting module, the modes that can be selected are: cooling mode and heating mode, the corresponding cooling mode can choose the lower limit of temperature energy saving, and the corresponding heating mode can also choose energy saving upper temperature limit. Cooling mode and heating mode can be selected individually or simultaneously.

Also select the communication address of the air conditioner indoor unit C. Example 1: If you choose C3 air conditioner indoor unit, the cooling mode, the energy-saving temperature is 27 degrees; the heating mode, the energy-saving temperature is 20 degrees. It means that when the C3 indoor unit of the air conditioner is running in cooling mode, the set temperature range that can be operated is 27 degrees to 30 degrees; when it is operated in heating mode, the set temperature range that can be operated is 17 degrees to 20 degrees.

Step S120, setting and saving the corresponding energy-saving temperature ranges of the cooling mode and/or heating mode according to the energy-saving setting command.

In this embodiment, specifically, the air-conditioning indoor unit C operates at a temperature within the energy-saving temperature range close to the temperature to be set by the temperature adjustment instruction.

For example, if the upper computer A sets the energy-saving temperature of the air conditioner indoor unit C3 to 26 degrees in the cooling mode and 20 degrees in the heating mode (in the cooling mode, the operating temperature range is 26 degrees to 30 degrees; in the heating mode , the set temperature range that can be operated is between 17 degrees and 20 degrees). Later, it received a temperature adjustment command from the remote control or wire controller that the cooling mode setting temperature is 23 degrees. At this time, the indoor unit C3 of the air conditioner needs to judge whether it is cooling mode or heating mode because it has an energy-saving setting command. Now it is receiving In the cooling mode, you need to enter the cooling energy-saving judgment module for judgment. According to the energy-saving temperature is 26 degrees, the set temperature is 23 degrees, which is the lower limit of the energy-saving temperature range. In order to save energy, at this time, the indoor unit is forced to run at the energy-saving temperature. If the cooling mode setting temperature of the remote control or wire controller is set to 28 degrees, 28 degrees is in the energy-saving temperature range—the upper limit of 26 degrees, which belongs to the energy-saving setting. At this time, the air conditioner indoor unit C3 will Set temperature to run.
