CONTROL INFORMATION
POWER ON LED
A green LED is ON when power is applied to the control and the microprocessor is operating properly.
SERVICE REQUIRED
If the message “For Service Call” or “Service Required” displays in the window of the control without
showing the time of day, the control valve has encountered a problem, such as failure to reach the proper
position during regeneration. The valve, the motor assembly, and board must be checked to diagnose and
fix this problem.
Notice
It is normal for the message ‘For Service Call’ followed by a phone number to scroll across the second line
of the display. The time of day & capacity remaining will appear on line 1 during normal operation.
TIME CLOCK
The time clock maintains the time of day for an extended period of time in the event of power loss. A super
capacitor provides this function and eliminates the need of a battery. In the event the power is off past the
charge of the capacitor only the time of day is lost. The rest of the programming is stored in the memory
and will not need to be reprogrammed. When the power is restored the clock will restart at 8 AM and will
need to be reset.
REGENERATION
Once an immediate regeneration is requested, a complete regeneration must occur to clear the request.
Once the regeneration starts, it must finish or the computer board will not clear. Manually walk (scroll) the
control through regeneration to clear the computer board. If the regeneration is aborted and the request is
not cleared, another immediate regeneration will occur.
HIGH-SPEED MOTOR OPERATION IN THE REGENERATION MODE
High-speed motor operation is achieved while stepping the control through the regeneration cycle.
Pressing the scroll button a second time, while in regeneration, activates the higher speed.
PROGRAM LEVELS
To enter any of the program levels, the control must display the time of day and gallons of capacity
remaining (Service Mode).
The system has three program levels available:
1. The Installer’s Level: To access the Installer’s Level, you must enter the five key sequence code
located on page 11. Please refer to pages 11-16 for programming information.
2. The End User’s Level: The End User’s Level does not require a special code to access. Please refer
to page 15 for programming information.
3. The Diagnostic Level: Please refer to page 17 for information.
