Abstract
PURPOSE: To simplify a display unit and improve appearance and use convenience by enabling a time-sharing display of an air conditioning room temperature and set temperature on a display unit.
CONSTITUTION: With a power switch 2 closed, analog switches 25 and 26 transfer the potential of a thermistor 11, which alternately detects the air conditioning room temperature according to the period of the oscillation frequency of an astable multivibrator 27, and the set potential of a variable resistor 17 for set temperature to an amplifier 12. The amplifier 12 amplifies the input voltage and feeds it to an A/D converter 13, and the latter turns on one of the luminous diode group 15 according to the input voltage level. Because the input voltage shows alternately the voltage corresponding to the potential of the thermistor 11 and the voltage corresponding to the set potential, the group 15 accordingly turns on and off and the discrimination between the air conditioning room temperature and the set temperature is conducted through the lenght of the turn-on time.
