is a VARTA, TYPE V7/8H (AccuPlus Nickle Hydride Ni-
mh 9v 150 mAH, No. 5522). A standard non-
rechargeable battery is an option for backup but needs
to be replaced periodically.
Level IV Day of Week Regeneration
It is now possible to program individual days that the
system will regenerate regardless of water usage.
When programmed, this feature will override the
demand regeneration and will reset capacity remaining
upon completion of the regeneration. This feature
insures that a regeneration will occur on programmed
days. All other times the system will operate as a
demand system. Level IV must be accessed to
program Day of Regeneration. Simultaneously press
the LEFT and DOWN arrow buttons for 3 seconds to
gain access and then press the UP or DOWN arrow
buttons until the desired Day location (1-7) is displayed.
Press the LEFT arrow button to display value in the
location, 0 = no Regeneration - 1 = Regeneration. To
program a regeneration for a specific day, go to that
day and change the 0 to 1. A regeneration will occur at
the time that is programmed into P2. A regeneration will
occur every week on the day(s) that is (are)
programmed with a 1.
Level III Memory Locations
To assist in troubleshooting the Water Conditioning
System, the contents of the controller memory can be
examined to determine the status of the control and the
history of water usage. To view the controller’s memory
locations “L1” to “L15” described in Table III, the
location viewing mode must be selected. This mode
can be selected by simultaneously pressing the
LEFT (
←
) and the UP (
↑
) buttons. The control will then
show “L1” on the display. Locations can be stepped
through in the same method as described for Level II
programming. However, the [SET] button is inactive
except for L4.
If [SET] is pressed when L4 is
displayed, Peak Flow is reset to zero. If [SET] is
pressed when any other location is displayed, the
control will beep.
