PURPOSE:To shorten the test timing of a controller, by means of setting up a test switch as an outer input of CPU, and of testing by taking the state of switch thereof in CPU. CONSTITUTION:An air conditioner is controlled by means of setting temp., time, and ON-OFF time of a timer by operating keys K1-K8. If ON of a test switch 4 at the test time, CPU 1 reads the state of the test switch 4 and stands a test flag. If the test flag may be standed, CPU 1 shortens the timing of temp. measurement to one second from normal 10 second, and changes over the timing of a restart prevention to 10 second from three minute, and changes over the coincidence judging interval of the timer time to one second from normal one minute. Owing to these, the test and regulation of a controller can be easily effected in a short time. |
