DEMAND TIMER FEATURES, SETTINGS, AND SERVICE, continued
setting: MODEL CODE, 12 OR 24 HOUR CLOCK, AND GALLONS OR LITERS MEASURE . . .
NOTE: The model code is factory set at assembly and testing. The hour clock and water measure have factory
set default values. The defaults are: 12 or 24 hour clock -- 12; Gallons or liters measure -- gallons. The model
code should never require resetting, but to check, or to set if previously omitted, read below. The defaults suit
most installations. However, to make a change, read and do the following.
MODEL CODE: The timer must have the right mod-
el code set to operate the softener correctly. The
correct code settings are:
" For model NSC30UD1 it must show A 27.
" For model NSC40UD1 it must show A- -31.
" For model NST45UD1 it must show A- -39.
" For model NST70UD1 it must show A- -68.
If A - - - is flashing in the display, do steps 2, 3, 5
and 7.
To check for the correct code setting, and to reset
if needed, do steps 1, 2, 3, 5 and 7.

displays are in standard clock time, 12:00AM to
11:59PM. If 24 hr is set, time displays are in military
time... 0100 (1:00AM) to 0000 (midnight). To change
from the 12 hr setting, do steps 1, 3, 4, 5, and 7.
GALLONS OR LITERS MEASURE: All water flow
rate and usage displays are in gallons with the de-
fault GALS setting. If reset to litErs, the same dis-
plays are shown in liters. Use steps 1, 3, 5, 6 and 7
