Abstract
A remote control card having a temperature sensor for detecting and measuring an ambient temperature, an inputter for setting a desired temperature, a transmitter to transmit a temperature signal from the temperature sensor and a temperature signal set by the inputter to a remote place through its transmission and reception antenna, an instruction signal generator for generating an instruction signal for automatic adjustment of wind direction, wind velocity or temperature when the difference between the ambient temperature and a predetermined reference temperature, or between the set temperature and reference temperature exceeds a predetermined value, and a display for indicating the ambient temperature measured by the temperature sensor, the temperature set by the inputter, or a temperature inputted from an external signal transmitter and receiver. There is also a controller for use with the above card.
