Description

  The present invention relates to a remote control device (central control device) for setting a temperature setting range of an air conditioner.

  Conventionally, an air conditioner having a function of switching and operating a set temperature of an air conditioner has a set input means such as a main body operation unit or a remote controller to set the indoor set temperature, cooling operation or heating operation and its operation mode, Setting input conditions such as the air volume mode and timer mode of the inner blower are input and stored in the memory, and the indoor temperature detected by the room temperature sensor and the set temperature stored in the memory are compared by the comparison means to control the operation. (For example, see Patent Document 1).

FIG. 4 shows a conventional installation state described in Patent Document 1. In FIG. As shown in FIG. 4, it is composed of a control unit microcomputer 101, setting input means 102, room temperature sensor 103, save operation switch 104, compressor 105, memory 106, comparison means 107, and operation condition setting means 108.
