VALVE POSITION INDICATORS:
Depending on the valve position, the following indica- tors show in the display:
Indicator | Valve Position |
Serv | Service |
Fill | Fill |
Brine | Brining/Brine Rinse |
Bkwsh | Backwash |
Rinse | Fast Rinse |
When the valve is rotating from one cycle to another, both indicators flash. For example, if the valve is in transition between fill and brining, both Fill and Brine flash. Upon reaching brining position, Fill goes off and Brine is on steady. The time display shows the minutes of the cycle remaining.
NOTE: If the faceplate is left in a diagnostic display (or a flashing display when setting times or hard- ness), present time automatically returns if a button is not pressed within 4 minutes. To return to the diagnostic display, repeat step 1.
OTHER INFORMATION
While in this diagnostic screen, the following information is available and may be beneficial for various reasons. This information is retained by the computer from the first time electrical power is applied to the faceplate.
•Press and hold the UP button to display the number of days this faceplate has had electrical power applied.
•Press and hold the DOWN button to display the num- ber of regenerations initiated by this faceplate since the model code number was entered.
•Press the REGENERATION button to advance the valve to each position and observe the switch and position indicators to verify component operation, or to possibly isolate a defect.
•Press and hold the SELECT button for 3 seconds until either S 25 or S 26 shows in the display, see Fig. 51.
This code identifies the softener nominal capacity size. If the wrong number shows, the softener will operate on incorrect programming. Do the following as needed.
S 25 or S 26 does show: Press the SELECT button to return to the present time display.
To change the number: Press the UP or DOWN but- ton until the correct code shows. Then, press the SELECT button and reset the timer.

TIMER PWA REPLACEMENT
Be sure the valve is in service position when replacing the timer PWA (observe valve cycle indi- cator). If after installing and programming the replace- ment timer PWA, the valve is not in service position, do the following to assure correct cycle orientation, or tim- ing, between the faceplate and valve.
Use the MANUAL ADVANCE procedures with the REGENERATION button, advance through the recharge cycles until the valve stops in service position, and RECHARGE no longer flashes in the display.
NOTE: The valve motor may automatically drive through several valve positions while searching for service. If an error code occurs, unplug the trans- former, then plug in again.
