How to use the Menu
In this section we are only worried about the COM column.

For example:
Alarms COM XFR
EEPROM Fail > OFF OFF
Airflow> ON OFF
Ret Hi Temp> ON OFF

The first column (before the >) is the event. If that event has an "ON" in the "COM" column, then it will generate a common alarm (Normally Open and Normally Closed will change states) if that event were to happen. If that event has an "OFF" in the "COM" column, then it will not generate a common alarm if that event were to happen.

NOTE: If the power were to go off while the AC is powered on, there will IS NOT A COMMON ALARM GENERATED went the unit comes back on. The unit will go back to same state it was before the power went off and an alarm will appear on the display and red alarm button will be lit.

NOTE:If the AC is powered off after being on from the On-Off button on the display, this will generate a common alarm while it is off if the KEYPAD OFF event is set to "ON" in the "COM" column in the Alarm Menu section.
