Normal Operation - EcoWater Calex 11 Installation And Operating Manual

Programming the Water Softener
Hardness Unit
French degrees (°f)
German degrees (°dH)
Parts per million (ppm)
NOTE: If your water supply contains iron, compen-
sate for it by adding to the water hardness
number. For example, assume your water is
20 gpg hard and contains 2 ppm iron. Add
5 to the hardness number for each 1 ppm of
iron. In this example, you would use 30 for
your hardness number.
2 ppm iron x 5 = 10
(times)
2. When finished setting your water's hardness num-
ber, press the SELECT/MENU button, and the
display will change to show the "Recharge Time"
screen.
C. SET RECHARGE START TIME
1. The softener's default recharge start time is 02:00
(See Figure 5). This is normally a time of day
when water is not being used in the household.
Hard water bypasses the softener if the household
draws water during the recharge cycle. If a differ-
ent recharge start time is desired, press the
q
or DOWN buttons to change the time, in 1-hour
increments.
2. When the desired recharge start time is displayed,
press the SELECT/MENU button, and the display
will return to the normal run (time of day) screen.

OPTIONAL RECHARGE CONTROLS
Sometimes a manually initiated regeneration may be
desired or needed. Two examples are:
= You have used more water than usual (house
guests, extra washing, etc.) and you may run out
of soft water before the next scheduled recharge.
= You did not refill the storage tank with salt before it
had run completely out.
Use one of the following two features to begin a
regeneration either immediately or at the next preset
regeneration start time:
RECHARGE NOW
To manually start a regeneration cycle, press and
hold the RECHARGE button for a few seconds, until
"RECHARGE NOW" flashes in the display. The
softener begins an immediate regeneration. When
completed (in about two hours), you will have a new
supply of soft water. Once started, you cannot cancel
this regeneration.
RECHARGE TONIGHT
To set a regeneration cycle to begin at the next pre-
set regeneration time, touch (press, but do not hold)
the RECHARGE button. "RECHARGE TONIGHT"
flashes in the display. A regeneration will occur at
the next preset regeneration start time. If you decide
to cancel this regeneration before it starts, touch the
same button once more.
VACATION NOTE
Calex demand water softeners, as set at the factory,
regenerate only while water is being used and soften-
ing capacity must be restored. For this reason, the
softener will not regenerate when you are away from
home for extended periods. However, if you set the
"Maximum Days Between Regen erations" feature, the
softener will regenerate even when no water is used.
