About Alarms

If any of the temperature controllers detect an alarm condition, two indicators

notify the operator.

The alarm indicator on the lower panel lights, and an alarm message flashes in

either the upper or lower readout of the Home display. Alarms can be

acknowledged by pressing the page or scroll buttons on the display on the

affected control module.

On the control modules, new alarms are displayed as a double flash, followed by

a pause. If there is more than one alarm, the display cycles through the relevant

alarm conditions.

There are two types of alarms: Process and Diagnostic.

Process Alarms

Process alarms warn of a problem with the process being monitored by the

controller.
