Note: If no alarms exist, then the screen displays the message shown for No Alarms!
If ANY alarm exists then the three lines display one of the messages shown
above.
The Cooling Failure and Heating Failure alarms are generated as follows:
As the unit enters the cooling mode, the current Supply Air Temperature reading
is stored in memory. After 10 minutes, if the temperature hasn’t changed by 5°F a
Cooling Failure alarm is generated.
A Heating Failure is generated in the same manner, only during the heating mode
instead of the cooling mode.
The Hi Space Temp and Lo Space Temp Alarms are generated as follows:
If the space temperature gets 5°F above the cooling setpoint, a Hi Space Temp
Alarm is generated. If the space temperature gets 5°F below the heating setpoint,
a Lo Space Temp Alarm is generated.
