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 Isobar 2 will motor to a shut off position
to prevent constant flow to drain. Depending upon system pressure and other factors, it is
possible to observe a reduced flow to drain during this step. After power is restored, the Isobar
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 will be affected.
Control Start-Up Procedures
Starting Extra Regeneration Cycle
1. To Start Delayed Extra Cycle Example ( 1 ) -
If Days Remaining Until Next Backwash does not read ‘1’, press and hold the
Set/Change button for 3 seconds until the display reads ‘1’.
- Backwash cycle will initiate at the next designated backwash time.
2. To start Immediate Extra Cycle First complete above step.
- With Days Remaining Until Next Regeneration at ‘1’.
- Press and hold the Set/Change button.
- After 3 seconds, the backwash cycle will begin.
3. To Fast Cycle thru regeneration First complete above 2 steps.
Note: Press and hold the Set/Change button for 3 seconds to advance to the next cycle step.
Fast Cycle is not necessary unless desired to manually step through each cycle step.
(Repeat until valve returns to the home display)
