About water softener system.
Service: Regeneration and Heavy Duty Backwash
NOTE: Each of the following functions has a factory set default value. The defaults are: Regeneration
start time –2:00AM ; Maximum days between regenerations –0 (display shows dY–); Heavy duty
backwash –OFF. The defaults are suitable for most installations. However, depending on water
supply quality, household peak water use hours, etc., adjustment is available to meet specific needs.
To make a change, read and do the following.
Regeneration (Start) Time: At the 2:00 AM regeneration start time, the water softening system begins
regeneration at that time, ending at about 4:00 AM. This is a good time in most households because
water is not in use (see Automatic Hard Water Bypass During Regeneration section). If a different time
would be better for your needs, do steps 1, 2, 3, 5, 7, 8 and 9 below to change the starting hour.
Maximum Days Between Regeneration: The default setting (dy-) allows the timer to control
regeneration frequency based on water usage readings from the water meter. It provides the
most economical operation. You can set a maximum time (in days) between regenerations.
For example, no more than three days will pass without a regeneration occurring if you set dY 3
in the display. A 1 to 7 day setting is available. To make a change from the default setting,
do steps 1, 2, 3, 5, 7, 8 and 9 below.
Heavy Duty Backwash: When set to ON, the backwash cycle of regeneration will be 10 minutes long
instead of the normal seven minute length. This is beneficial on some water supplies high in iron
or sediment content. To conserve water, on clean supplies, be sure the default setting OFF shows.
To change this setting, do steps 1, 2, 3, 5, 7, 8 and 9 below.
Auto Regeneration When Capacity is Low: The softener will regenerate at the regeneration time only.
Although the control has a look-forward feature which anticipates normal demand, an unusually
high usage may result in a loss of softening capacity. Turning the feature ON will cause the softener to
go into a regeneration cycle when 97% of the softening capacity has been used. To change settings,
do steps 1, 3, 5, 7, 8 and 9.
