Nortec SETC Warnings and Faults

The self-diagnostic system built into the SETC is continually monitoring the operation of the
humidifier.
Warnings
 When problem symptoms are detected, the Nortec SETC will attempt to take self-corrective
actions to try to correct the problem. A warning is displayed on the screen for information
purposes and the humidifier continues to operate.
 If the condition which generated the warning is eliminated the warning is cleared from the
display.
Faults
 If the humidifier is not able to self correct a problem symptom it will if necessary respond by
shutting itself down.
 When this occurs the humidifier illuminates the red "Fault" LED, shuts off the signal to the
CV valve actuator, and activates the "Error" relay of the remote relay board.
Clearing a Fault
 Check the fault message that the humidifier is displaying and take any necessary actions to
correct the cause(s) as outlined in Table 13, Troubleshooting Warnings and Faults.
 Power cycle the humidifier with the On/Off switch waiting 3 seconds between turning it off
and on.
