Abstract

The present invention is provided with a remote controller case having an opening for air intake. The remote controller case includes a circuit board provided with a temperature detection circuit. The circuit board has a temperature sensor 26 corresponding to the opening for air intake. When the air-conditioning apparatus is installed, the output data of the temperature sensor 26 are corrected according to the installing environment. After the air-conditioning apparatus is installed, the output data of the temperature sensor 26 are corrected to have a temperature lowered by a predetermined degree to make the remote controller perform a temperature control operation.

Claims

1. A remote controller for an air-conditioning apparatus comprising:

a remote controller case (1) having an opening for air intake (5);

a circuit board (10) having a temperature detection circuit stored in said remote controller case (1); and

a temperature sensor (26) provided in said circuit board (10) in such a manner as to correspond to said opening for air intake (5),

wherein said remote controller further comprises;

a temperature sensor output data correction means (43) for correcting output data of said temperature sensor (26); and

a temperature data correction setting means for determining whether or not to operate said temperature sensor output data correction means (43).

2. The remote controller for an air-conditioning apparatus of claim 1, wherein

said temperature sensor output data correction means (43) is so structured as to correct said output data of said temperature sensor (26) in such a manner as to lower said output data by a predetermined degree of temperature.

3. The remote controller for an air-conditioning apparatus of claim 1 or 2, wherein

said temperature data correction setting means is composed of a jumper wire (24) provided on said circuit board (10) in such a manner as to correspond to said temperature sensor (26), and is so structured as to operate said temperature sensor output data correction means (43) based on a cut of said jumper wire (24).

4. The remote controller for an air-conditioning apparatus of claim 1 or 2, wherein

said temperature data correction setting means is composed of a switch provided on said circuit board (10) in such a manner as to correspond to said temperature sensor (26), and operates said temperature sensor output data correction means (43) based on an ON condition of said switch.
