System messages
The PHD 200 control system constantly monitors internal operating conditions. If the system detects a problem, it will pro-
duce an error (“ER”) message. If the display shows an ER message, first unplug the unit and then plug it back in. This will
usually reset the electronics, and the unit will begin operating normally. If the error message reappears, refer to the expla-
nation and solution shown below. If this still does not fix the problem, contact your local authorized service center or call
the Dri-Eaz Service Department at 800-932-3030.
NOTE: The message “POWER FAILURE” is not a system error. When this message is displayed, it indicates that
power to unit was interrupted and then restored. To clear the message, press the MENU SELECTION key.
