Normal Operation
1. Home Display
a. Alternates between the display of Time of Day and Number of Days until the Next
Backwash. (Metered softeners will alternate between time of days and gallons remaining until next regeneration)
- Days Remaining until the Next Backwash will count down from the entered value until it reaches 1 day
remaining.
- A Backwash Cycle will then be initiated at the next designated regeneration time.
2. Battery Back-Up (Uses a standard 9-volt alkaline battery.)
Features of Battery Back-Up:
• During power failures, the battery will maintain the time of day as long as the battery has power. The
display is turned off to conserve battery power during this time. To confirm that the battery is
working, press either button and the display will turn on for five (5) seconds.
• If power failure occurs while system is regenerating, the Signature 2 will motor to a shut off position
to prevent constant flow to drain. After power is restored, the Signature 2 will return and finish the
cycle where it left off prior to the power interruption.
• When used without battery back-up, during a power failure, the unit stops at its current point in the
regeneration position and then restarts at that point when the power is restored. The time will be
offset by the increment of time the unit was without power, so it is necessary to reset the time of day
on the unit. No other system settings will be affected.
Starting Extra Regeneration Cycle
1. To Start Delayed Extra Cycle Example [ 1 ]
- If Days Remaining Until Next Regeneration does not read ‘1’, press and hold the
Set/Change button for 3 seconds until the display reads ‘1
- Regeneration cycle will initiate at the next designated regeneration time.
2. To start Immediate Extra Cycle First complete above step.
- Press and hold the Set/Change button.
- After 3 seconds, the regeneration cycle will begin.
3. To Fast Cycle thru regeneration First complete above 2 steps.
Press and hold the Set/Change button for 3 seconds to advance to the next cycle step.
Note: Fast Cycle is not necessary unless desired to manually step through each cycle
step.(Repeat until valve returns to the home display)
