Pressing the alarm key will perform the following two functions:
1. The controller will be prompted to attempt a reset of any critical shutdown
alarms that have occurred. If the critical shutdown condition is no longer
active, the controller will re-enable the unit.
2. The controller will clear any of the non-critical alarms that are no longer active.
