Temperature/Humidity Sensor Error (Main)
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
degrees centigrade (if there is a problem with the temperature sensor) and/or the
humidity is 50% (if there is a problem with the humidity sensor)
