Temperature/Humidity Sensor Error (PCU)
One of the following occurred.
 The temperature sensor output was less than 0.5V or more than 2.8V for
three seconds (one second x 3), indicating a problem with the temperature
sensor.
 The humidity sensor output was more than 2.4V for three seconds (one
second x 3), indicating a problem with the humidity sensor.
Details:
Detection is repeated after power off/on.
If either of temperature/humidity sensors works correctly, the working sensor will
be used even after the SC is issued.
The machine continues working with the assumption that the temperature is 23
