8a. Efficiency mode: If the desired efficiency
m
ode already has a black dot next to it (See
Figure 74), go to Step 9. Otherwise, press the
D
OWN q or UP p buttons to scroll to the
desired efficiency mode, then press OK /
MENU to choose it.
=Salt efficient limits available salt doses to
maintain 4 mol/kg of salt efficiency. Units may
recharge more frequently.
=Auto adjusting is the default. It automati-
cally adjusts salt doses to target a 3-4 day
interval between recharges. Recommended.
=High capacity is for applications where very
low “bleed” (less than 1.5 ppm) of hardness
can be tolerated. Such applications include
water for boilers. This setting will consume
higher quantities of salt.
8b. Maximum days between recharges: Press
the UP p or DOWN q buttons to change the
number of days (See Figure 75). The feature
can be set from 1 to 15 days. Setting the
number of days below 1 turns the feature off
and defaults to automatic control of recharg-
ing. Default is Auto.
8c. 97% feature: If the desired option already has
a black dot next to it (See Figure 76), go to
Step 9. Otherwise, press the DOWN q or UP
p buttons to scroll to the other option, then
press OK / MENU to choose it. If this feature is
On, the softener will automatically recharge
when 97% of capacity is used, at any time of
day. Default is Off.
