(3) Data bits: the data bit has two states, namely a state 0 and a state 1, the duration corresponding to the state 1 is 2 times that of the state 0, the time is a relative concept, an operator can realize the data bit only by using the default number with relatively stable intervals in the heart, the requirement on the operator is very low, for example, the slow number 1 is switched to realize 0, and the slow number 1-2-3 is realized to realize 1, so long as the time length of the start bit is not exceeded.
<1> when three data signals appear consecutively after the start signal and the on and off durations are within the shortest 2 times, the three signals are all considered as 0 or 1 states, i.e., the signal combination is 000.
<2> when three data signals appear consecutively after the start signal and the on and off durations are 2 times or more the shortest, 0 for less than 2 times the shortest, 1 for more than 2 times the shortest, 6 possible signal combinations can be formed: 001. 010, 011, 100, 101, 110.
<3> when more than three data signals appear consecutively after the start signal, the signal after the 3 rd signal is discarded.
<4> when there are less than three consecutive signals between the start signals, 1 to 2 signals that have been received are discarded.
<5> note that since the 0, 1 states are relatively compared, there is no signal combination of 111.

000: the state overturning of the machine switch is realized;
011: set to minimum temperature
100: setting to a maximum temperature;
