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.

Claims

1. A remote control card comprising:

temperature sensor means for detecting and measuring a first ambient temperature at the remote control card;

input means for setting a desired temperature;

card transmitting means for transmitting a signal derived from the temperature signal from the temperature sensor means, the desired temperature set by the input means, and a second ambient temperature measured at a remote place to an external transmission and reception means; and

display means for indicating the first ambient temperature measured by the temperature sensor means, the temperature set by the input means, or the second ambient temperature measured at a remote place.

2. A remote control card as in claim 1, further comprising:

card receiving means for receiving a signal transmitted by an external signal transmission means corresponding to the second ambient temperature.

3. A remote control card as in claim 1, further comprising:

switching means for turning off the card transmitting means when the card receiving means is receiving a signal.

4. A remote control system comprising:

a first transmission and reception means equipped with a transmission and reception antenna located at a distance from a remote control card and adapted to sense an ambient temperature of a location of said first transmission and reception means;

a second transmission and reception means on the remote control card;

control means for controlling the wind direction, velocity and temperature in response to a first signal from the second transmission means of the card wherein the signal is derived from the ambient temperature of the remote control card and an ambient temperature measured at the control means; and

a heat output controller connected to the control means through a wire harness and equipped with built-in means for controlling the wind direction, wind velocity, or temperature according to the control means.

5. A remote control system as in claim 4, wherein:

the card comprises input means for setting a desired temperature; and

the first signal from the card is the calculated difference between the ambient temperature of the remote control card and the temperature signal set by the input means.

6. A remote control system as in claim 4, wherein the first transmission and reception means transmit the ambient temperature measured at the control means to the remote control card.

7. A remote control system as in claim 6, wherein the remote control card comprises switching means for turning off the card transmitting means when the card receiving means is receiving a signal.

8. A remote controller as in claim 4, wherein there are a plurality of the remote control cards and the control means controls the wind direction, velocity and temperature in response to a signal from at least one of the plurality of remote control cards.

9. A remote controller as in claim 8, wherein there are a plurality of built-in means for controlling the wind direction, each of said built-in means being directed to a position of one of the plurality of control cards.
