1. A battery powered apparatus for remotely adjusting the temperature of a closed environment having a heating/cooling unit comprising:

  • (a) a means for encoding a desired temperature into series of pulses havingan up-temperature signal for increasing a preset temperature setting by an incremental step above the preset temperature;

    a down-temperature signal for decreasing the preset temperature setting by the incremental step below the preset temperature;

    a preset temperature signal for changing the closed environment temperature to the preset temperature by activating the heating/cooling unit;

    an up-preset temperature signal for increasing the preset temperature by the incremental step; and

    a down-preset temperature signal for decreasing the preset temperature by the incremental step to decrease the preset temperature by the incremental step;

    (b) a means for generating a radio frequency carrier;

    (c) a means for modulating the radio frequency carrier with the series of encoded pulses which modulating means is operatively connected to the encoding means and with the radio frequency carrier generating means;

    (d) a transmitter for transmitting the modulated radio frequency carrier which transmitter is operatively connected to the modulating means;

    (e) a receiver for receiving the modulated radio frequency carrier which receiver is in spaced relation to said transmitter;

    (f) a means for demodulating the series of pulses from the radio frequency carrier which demodulating means is operatively connected to the receiver;

    (g) a means for decoding the series of pulses into the desired temperature which decoding means is operatively connected to the demodulator;

    (h) a means for comparing continuously two temperatures which comparing means is operatively connected to the heating/cooling unit so that any significant difference between the two temperatures causes the heating/cooling unit to activate and which comparing means is in communication with the decoding means so that the desired temperature is communicated to the comparing means and is one of the two temperatures compared; and

    (i) a means for continuously sensing a temperature of the building which temperature sensing means is in communication with the comparing means so that the closed environment temperature can be compared to the desired temperature.
