stored in memory. The product water conductivity is displayed in the large
numbers at the top center of the display. The temperature is displayed as degrees
Celsius in the top right corner of the display. The mode of operation is displayed

Configuration Screen
Press the SELECT button to view the configuration screen. The software revision
level is displayed in the upper right corner of this screen. While the configuration
screen is displayed, the SELECT button moves the highlight cursor to the next

ACCEPT button saves all of the values and brings up the timer screen. The
RESET button discards all changes and brings up the timer screen. If no input is
detected for a continuous 30 seconds, the controller will discard all changes and
return to the operation screen. An asterisk appears next to a field whenever the
value of the field equals the value stored in memory. The configuration screen
contains the following field with their options:
MODE: (direct feed, tank feed, and standby)
LOW QUALITY: (2-200 micromhos) This is the set point for the diverter valve.
When the product water conductivity is equal to or greater than value selected, the
diverter valve output will be energized and the low quality LED will turn on.
AUTOSTART: (on/off) if "on" is selected, the system will automatically restart
after a power loss. If "off" is selected, the unit will not restart after a power loss.
LOWPRESSURE RETRY: (0-10) This is the number of times the system will
attempt to restart after a low pressure shutdown.
LOW PRESSURE DELAY: (15-90 seconds in 15 second increments) This is the
amount of time between attempts to restart after a low pressure shutdown.
