Normal Operation, Control Displays

During normal operation, the present time of day and AM or PM show in the control display area. When

the demand computer determines a regeneration is needed, RECHARGE TONIGHT begins to flash in the display

along with the present time. RECHARGE TONIGHT PM flashes until the next regeneration start time, then

RECHARGE TONIGHT

changes to RECHARGE NOW, which flashes until the regeneration is over.

Feature: Optional Recharge Controls

Sometimes, a manually started regeneration (recharge) may be desired or needed. Two examples:

■You have used more water than usual (house guests, extra washing, etc.) and you may run out of soft water before the next regeneration.

■You did not refill the storage tank with salt.

Use one of the following features to start a regeneration immediately, or at the next preset regeneration start time.

RECHARGE TONIGHT	PM
	RECHARGE TONIGHT

Touch (do not hold) the TOUCH or HOLD button. RECHARGE TONIGHT flashes in the control display area. A regeneration will occur at the next preset regeneration start time. If you decide to cancel this regeneration, touch the same button once more.

RECHARGE NOW	PM
	RECHARGE NOW

Press and hold the TOUCH or HOLD button until RECHARGE NOW starts to flash in the control display area. The water softening system begins an immediate regeneration and, when over in about two hours, you will have a new supply of soft water. Once started, you cannot cancel this regeneration.

Feature: Program Memory

If electrical power to the water softening system is interrupted, the control display is blank, but the control keeps correct time for about six hours. When power is restored, you have to reset the present time only if the display is flashing. All other settings are maintained and never require resetting unless a change is desired.

If the time is flashing after a long power outage, the water softening system continues to work as it should to provide you with soft water. However, regenerations may occur at the wrong time of day until you reset the control to the correct time of day.

Feature/Service: Automatic Electronic Diagnostics

The control computer has a self-diagnostic function for the electrical system (except input power and water meter). The computer monitors the electronic components and circuits for correct operation. If a malfunction occurs, an error code appears in the control display.

The chart on Error Codes shows the error codes that could appear and possible reasons for each code. While an error code is displayed, all control buttons are inoperable except for the SELECT button. SELECT remains operational so the service person can make the Manually Initiated Electronic Diagnostics to further isolate the defect and check the water meter.
