SETTING TIME OF DAY AND
INITIATING A MANUAL
REGENERATION
Setting the Time of Day
1. Press and hold either the Up or Down buttons until
the programming icon replaces the service icon and
the parameter display reads TD.
2. Adjust the displayed time with the Up and Down
buttons.
3. When the desired time is set, press the Extra Cycle
button to resume normal operation. The unit will
also return to normal operation after five seconds if
no buttons are pressed.
Queueing a Regeneration
1. Press the Extra Cycle button. The service icon will
flash to indicate that a regeneration is queued.
2. To cancel a queued regeneration, press the Extra
Cycle button.
Regenerating Immediately
Press and hold the Extra Cycle button for five seconds.
FEATURES OF THE SXT CONTROLLER
• Power backup that continues to keep time and the passage of days for a minimum of 8 hours in the event
of power failure. During a power outage, the control goes into a power-saving mode. It does not monitor
water usage during a power failure, but it does store the volume remaining at the time of power failure.
• Settings for both valve (basic system) and control type (method used to trigger a regeneration).
• Day-of-the-Week controls.
• While in service, the display alternates between time of day, volume remaining or days to regeneration,
and tank in service (twin tank systems only).
• The Flow Indicator flashes when outlet flow is detected.
• The Service Icon flashes if a regeneration cycle has been queued.
• A Regeneration can be triggered immediately by pressing the Extra Cycle button for five seconds.
• The Parameter Display displays the current Cycle Step (BW, BF, RR, etc) during regeneration, and the
data display counts down the time remaining for that cycle step. While the valve is transferring to a new
cycle step, the display will flash. The parameter display will identify the destination cycle step (BW, BF,
RR, etc) and the data display will read “----”. Once the valve reaches the cycle step, the display will stop
flashing and the data display will change to the time remaining. During regeneration, the user can force
the control to advance to the next cycle step immediately by pressing the extra
cycle button.

A bypass should be installed on all water conditioning
systems. A bypass isolates the conditioner from the
home’s water system and allows unconditioned water to
be used in the home while the conditioner is undergoing
service or maintenance procedures or if the conditioner is
experiencing performance issues. Figures 4 - 7 show the
most common bypass methods.
Metal Bypass Valve
This type of bypass is located directly behind the conditioner
valve on top of the media tank. To bypass the conditioner
system using this type of bypass, turn the handle on top of
the bypass until the arrow on the handle is pointing to the
word BYPASS stamped on the bypass valve body.
To return the conditioner system to regular service, turn the
bypass handle until the arrow on the handle is pointing to
SERVICE (see Figure 4 Metal Bypass Valve).
Handle Style Plastic Bypass Valve
This type of bypass is located directly behind the conditioner
valve on top of the media tank. To bypass the conditioner
system using this type of bypass, turn both of the small
handles on the bypass until they are in the position shown in
Figure 5 Handle Style Plastic Bypass Valve, perpendicular to
the inflow and outflow plumbing.
To return the conditioner system to regular service, turn
both of the small handles on the bypass back to their
original positions, parallel with the inflow and outflow
plumbing.
Knob Style Plastic Bypass Valve
This type of bypass is located directly behind the conditioner
valve on top of the media tank. To bypass the conditioner
system using this type of bypass, turn both of the knobs
on the sides of the bypass clockwise until the holes in the
knobs are facing up as shown in Figure 6 Knob Style Plastic
Bypass Valve.
To return the conditioner system to regular service, turn
both of the knobs on the bypass counter-clockwise back to
their original positions.
Manual Bypass
This type of bypass system is plumbed into the home’s
water system, and generally consists of three valves: one
on the inflow line going into the conditioning system, one on
the outflow line coming out of the conditioning system, and
one on the bypass line connecting the inflow and outflow
lines (See Figure 7 Manual Bypass).
To bypass the conditioner system using this type of bypass
(following Figure 7 Manual Bypass), open Valve 2 and close
Valves 1 and 3.
To return the conditioner system to regular service, open
Valves 1 and 3 and close Valve 2.

CONTROL OPERATION DURING A POWER FAILURE
The SXT 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 8 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 valve system should include all required safety components to prevent overflows
resulting from a power failure during regeneration.
NOTE: After power is restored following a power failure, time of day will flash to indicate a power
interruption. Press the Extra Cycle button to resume normal operation.
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. If the treated
water output is important and power interruptions are expected, the system should be setup with a sufficient
reserve capacity to compensate for regeneration delays.
CARE AND USE OF YOUR BRINE TANK
Each time the softener regenerates, salty water (brine) is needed to recondition the media in the water tank.
The brine is pulled from the salt tank at a controlled amount. If the salt tank does not contain enough salt, the
brine is weak, the media will not fully recondition and untreated water will pass through. To ensure the highest
level of performance of your water conditioning system, please observe the following:
• Keep the brine tank filled with salt at all times. The salt level should always be higher than the water level
in the brine tank.
• Only use sodium chloride salt designed for water softeners. Other types of salt (rock or snow melting)
may contain dirt and chemicals that will affect the quality of your water and the performance of your
water softener.
• Keep the brine tank covered.
• Empty and clean the tank every three years.
