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 and 7 below to change the starting hour.

Maximum Days Between Regeneration: The default setting 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, 3, 4, 5 and 7 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 OFF shows. To change this setting, do steps 1, 3, 5, 6 and

7below.
