When starting up, the Four Zone Temperature Monitor checks each
temperature sensor input to verify that a sensor is connected.
If a sensor is connected and has a reading within range, “ok” will be
printed next to that sensors label.
If a sensor is not connected or has a reading out of range, “n/c” will be
printed next to that sensors label.
