Abstract

PURPOSE:To enable a remote controller to be applied to a concentrated control by a method wherein a temperature signal is outputted from a remote controller to an air conditioner only when a separate or respective control is carried out and an interior part of a room is air conditioned in response to a temperature near an operator. CONSTITUTION:A remote controller 3 may connected an air conditioner 2 to the first port 23 under a respective control of only one air conditioner and to the second port 24 when a plurality of air conditioners are concentrically controlled. It may perform a transmittance or a receiving operation between a control means 31a and an operation control means 21a. As a control discriminating means 21b discriminates a respective control, a temperature near an operator to be detected by a temperature sensing means 36 of the remote controller 3 is outputted to the operation control means 21a through an outputting means 31b. The air conditioning device 2 is controlled for its separated operation. In turn, when a concentrated control is discriminated by the control discriminating means 21b, a temperature signal got by a temperature sensing means 28 is outputted to the operation control means 21a through the outputting means 21c so as to perform a concentrated control. In this way, the remote controller can be applied to a concentrated control and then a comfortable characteristic of air conditioning can be improved.
