1. Query the threshold settings, and check whether the threshold is properly set:
  Y => The threshold is properly set. Go to procedure 2.
  
  N => The threshold is improperly set. Go to step b.
2. Change the temperature threshold that is improperly set.
  Change the threshold, and then check whether the alarm is cleared:
  
  Y => The alarm is cleared. No further action is required.
  
  N => The alarm is not cleared. Go to procedure 2.
Check the heat exchanger.
1. Check whether the heat exchanger works properly:
  Y => The heat exchanger works properly. Go to procedure 3.
  
  N => The heat exchanger does not work properly. Go to step b.
2. Repair the heat exchanger.
  Repair the heat exchanger, and then check whether the alarm is cleared:
