<p>Provided is an air conditioning machine for suppressing power consumption by a discharge resistance for discharging residual charge in a transmission path. An analog switch is inserted between two discharge resistances (R5, R6), and upon transmitting AMI signals to two lines (P1, P2) of a signal transmission path (4), an MCU (30) performs discharge control so that if a high level signal voltage is output, the analog switch (S1) is turned OFF, and if a low level signal voltage is output, the analog switch (S1) is turned ON.</p> |
