* These registers are mirrors of 9-11. They are used to indicate errors without sounding an alarm. They can be used to indicate when a problem is present
even when the alarm is shut off.
•• These bits will activate when the temperature is outside of the range set by the setoint and the deviation. This doesn not indicate an error.
