1. Check each outdoor temperature with the monitor mode of the board maintenance functions.
2. Measure actual temperature with a thermometer, and check for the sensor reading's extreme deviation from the
actual temperature.
3. Measure each sensor's resistance value at the terminals on the main board, and check for extreme deviation
from the standard value.
