Troubleshooting

Alarms —
The economizer module provides alarm messages that
display on the 2- - line LCD.
NOTE: Upon power up, the module waits 60 minutes
before checking for alarms. This allows time for all the
configured devices (e.g. sensors, actuator) to become
operational. The exception is the SAT sensor which will
alarm immediately.
If one or more alarms are present and there has been no
keypad activity for at least 5 minutes, the Alarms menu
displays and cycles through the active alarms.
You can also navigate to the Alarms menu at any time.
Clearing Alarms —
Once the alarm has been identified and the cause has been
removed (e.g. replaced faulty sensor), the alarm can be
cleared from the display.
To clear an alarm, perform the following:
1. Navigate to the desired alarm.
2. Press the button.
3. ERASE? displays.
4. Press the button.
5. ALARM ERASED displays.
6. Press the (Menu up/Exit) button to complete the
action and return to the previous menu.
NOTE: If the alarm still exists after you clear it, it is
redisplayed within 5 seconds.
