IV. Programming
Figure 6 shows the icons and display characters of the timer mecha-
nism.
When the Master Programming Mode is entered, all available option/
setting/displays may be viewed and set as needed. Depending on
current option settings, some parameters cannot be viewed or set.
This timer is used on other system configurations as well so it is
important that the user carefully programs the system in accordance
with the values shown on the Master Programming Chart.
A. Setting the Time of Day
1. Press and hold either the Up or Down buttons until the pro-
gramming 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 5 seconds if no buttons are pressed.
B. Entering Master Programming Mode
The master level programming has been set at the factory however
you should check the program against the Master Programming
Chart. With the control valve in the service position set the Time
Of Day display to 12:01 P.M. Press the Extra Cycle button (to exit
Setting Time of Day mode). Then press and hold the Up and Down
buttons together until the programming icon replaces the service
icon and the Display Format "DF" screen appears. Once you are in
the master programming screen, pressing the extra cycle button
will advance the controller to the next parameter. Pressing the up or
down buttons allows the user adjust each parameter’s value up or
down respectively.
C. Exiting Master Programming Mode
Press the Extra Cycle button to accept the displayed settings and
advance to the next parameter. Press the Extra Cycle button at the
last parameter to save all settings and return to normal operation.
The control will automatically disregard any programming changes
and return to normal operation if it is left in Master Programming
mode for 5 minutes without any keypad input.
V. Controller Operation
The factory default program settings should be adequate for most
installations.
A. Queueing a Regeneration
1. Press the Extra Cycle button. The service icon will flash to
indicate that a regeneration is queued. Regeneration will occur
that day at the programmed Regeneration Time (RT).
2. To cancel a queued regeneration, press the Extra Cycle button.
B. Regenerating Immediately
Press and hold the Extra Cycle button for five seconds.
Time Clock Delayed Control
A Time Clock Delayed Control regenerates the system on a timed
interval. The control will initiate a regeneration cycle at the pro-
grammed regeneration time when the number of days since the last
regeneration equals the regeneration day override value.
Control Operation During Regeneration
During regeneration, the control displays a special regeneration dis-
play. In this display, the control shows the current regeneration step
number, the valve it is advancing to, or has reached, and the time
remaining in that step. The step number that displays flashes until
the valve completes driving to this regeneration step position. Once
all regeneration steps are completed the valve returns to service and
resumes normal operation.
Pressing the Extra Cycle button during a regeneration cycle immedi-
ately advances the valve to the next cycle step position and resumes
normal step timing.
Control Operation During Programming
The control only enters the Program Mode with the valve in ser-
vice. While in the Program Mode, the control continues to operate
normally monitoring water usage and keeping all displays up to date.
Control programming is stored in memory permanently, eliminating
the need for battery backup power.
