The economizer controller provides alarm messages
that display on the 2-line LCD.
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.
N No otte e:: 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 MA
sensor which will alarm immediately.
