CONTROLLER ALARMS AND SIGNALS

The electronic controller can detect and signal several alarm conditions: high/low freezer temperatures,
door open and open or short-circuited temperature probes. If the alarm conditions last longer than pre-
programmed time delays, the controller will turn ON an audio signal (buzzer). Also a LED light located
in the upper left corner of the controller, next to the caution symbol, will glow in case an alarm is active.
Once the alarm conditions have been fixed, the controller will turn off the alarms on its own. Alarms can
be disabled by pressing any controller button, during alarm conditions
