Troubleshooting - Timer
If an error is detected, an error screen will alternate with the main display screen every few seconds, and the LED
light will be red.
During an error condition, the unit continues to monitor the flow meter and update the remaining capacity.
Once an error condition is corrected, the unit returns to the operating status it was in prior to the error, and
regeneration resumes according to normal programming. If an error is cleared by reprogramming the unit in
the Master Programming Mode, the volume remaining may be reset to the full unit capacity (as though it had
just regenerated). If an error is present, a regeneration can only occur manually by pressing and holding the
Extra Cycle button for 5 seconds. If the unit was in regeneration when the error occurred, it will complete the
regeneration cycle and go into service.
When the problem is corrected, and the error no longer displays (it may take several seconds for the unit to stop
displaying the error message), the unit will return to normal operation. The LED light will no longer be red, and
will turn Green if the unit is regenerating, or Blue if the unit is in service.
