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 devic-
es (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 re-
moved (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 (Enter) button.
3. ERASE? displays.
4. Press the (Enter) 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 clearing it, it is redisplayed
within 5 seconds.
