Diagnostic Functions
While in the diagnostic functions mode all keys will be active. The mode is entered by pressing the “Information” key, then the “Up”
key. These functions are used to perform diagnostics on the control during regeneration. The display shows the “Regen” icon solid
(if a regeneration is pending) or flashing (if in regeneration). The display is to show Current Cycle along the bottom (4-cycle valve:
Backwash, Brine Rinse, Fast Rinse/Refill; 5-cycle valve: Backwash, Brine Rinse, Fast Rinse, Refill). The program of the motor
output is to be shown in the 3rd digit from the right. The center bar of the digit will light for the motor being powered. The cycle time
remaining will be displayed in the two rightmost end digits along with the “MINS” icon. When in home position, the two rightmost
digits will alternate displaying “HM” (with “MINS” icon off), and time remaining (with “MINS” icon on) 2 seconds each. If an Aqua-
Sensor is connected, the 20-minute stabilization delay time will be displayed here after a regeneration (only if regeneration is
allowed to be completed on its own). If a flow meter is attached, the far left digit will show “F” solid, and flash if the control is getting
a flow signal from the flow meter. If an Aqua-Sensor is attached, the second digit from the left will show “A”. The “A” will be solid
for a balanced condition, and flash for an unbalanced condition. A typical display for this function is shown below.
Last Regeneration Trigger
The fourth digit from the left can be “F” (Flow Meter), “A” (Aqua-Sensor
®
), “t” (time clock) or “M” (Manual). If the “Regen” icon is off,
this letter stands for what triggered the last regeneration. If regen icon is on, this letter stands for what armed it.
