Use the arrows to choose ( select ) the letter "F" if used on Backwash Only Valve, otherwise ( if water softener ) you will be setting the Resin Capacity of your Water Softener.

Step Two: Resin capacity.

Capacities:

0.75 for 24K ( 3/4 cu.ft. )- most 8" diameter tanks

1.0 for 32K ( 1 cu.ft. ) - most 9" diameter tanks

1.25 for 40K ( 1.25 cu.ft.)

1.50 for 48K ( 1.50 cu.ft. ) - all 10" x 54" tanks

2.0 for 64K ( 2 cu.ft.) - most 12" diameter tanks

Press the set button to accept.

The unit will now display the time.
