RESETS
WARNING: USE OF THE RESET FUNCTIONS IS NOT RECOMMENDED EXCEPT UNDER THE
GUIDANCE OF A WATER TREATMENT PROFESSIONAL FAMILIAR WITH THIS EQUIPMENT.
Soft Reset:
Press and hold the EXTRA CYCLE and DOWN buttons for 25 seconds while in
normal Service mode. This resets all parameters to the system default values except days since
regeneration in the time clock system.
Master Reset:
Hold the Extra Cycle button while powering up the unit. This resets all of the
parameters in the unit. Check and verify the choices selected in Master Programming Mode.
CONTROL OPERATION DURING A POWER
FAILURE
The 2510SXT valve/controller includes integral power backup. In the event of power failure, the
control shifts into a power-saving mode. The control stops monitoring water usage, and the display
and motor shut down, but it continues to keep track of the time and day for a minimum of 48 hours.
The system configuration settings are stored in a non-volatile memory and are stored indefinitely
with or without line power. The Time of Day flashes when there has been a power failure. Press any
button to stop the Time of Day from flashing.
If power fails while the unit is in regeneration, the control will save the current valve position
before it shuts down. When power is restored, the control will resume the regeneration cycle from
the point where power failed. Note that if power fails during a regeneration cycle, the valve will
remain in it’s current position until power is restored. The drain line plumbing configuration should
include all required safety components to prevent overflows resulting from a power failure during
regeneration.
The control will not start a new regeneration cycle without line power. If the valve misses a
scheduled regeneration due to a power failure, it will queue a regeneration. Once power is restored,
the control will initiate a regeneration cycle the next time that the Time of Day equals the
programmed regeneration time. Typically, this means that the valve will regenerate one day after it
was originally scheduled.
