Control Valve Error Code Diagnosis
Under normal operating conditions, when your control valve is in the “in service” position, the display
should alternate between the current time of day and the number of days remaining (for lters and time
clock softeners) or gallons remaining (for metered softeners) until the next regeneration. This is the “home
display.” If the valve is currently going through a regeneration cycle, the display will show the cycle step
on the left side of the display and the number of minutes remaining in that step on the right side of the
display. If any other information is being displayed, then the valve is informing you of an issue. There are
ve error codes which could indicate an issue with the control valve. When an error is being displayed, the
valve will be in a stopped position, and the buttons will not respond to being pressed. Even if the cause of
the error code is corrected, the error code will not clear until the power supply has been disconnected and
reconnected (this will be referred to as “cycling” the power). All error codes are displayed as the letters “Err”
followed by a ashing number 2-6:
