Programming 1″ NWS Water Softeners
Default Settings when you receive the unit are
First Backwash = 8 minutes
Regenerant Draw (aka Slow Rinse or Brine Draw) = 60 minutes
Second Backwash = 8 minutes
Rapid Rinse = 8 minutes
Regenerant Refill (Brine Fill) = Varies according to the situation. The softener will figure this one out when it gets the necessary information.
The unit has five buttons. They are, from the left, Time, Next, Up, Down, and Regen.
The Time button is used to set the time of day to real time.
INSTALLER PROGRAMMING
To enter Installer Programming, press NEXT and DOWN simultaneously and hold for 5 seconds. (Sometimes you have to do it twice.)
You will know you’re in programming mode when the screen shows TYPE. Scroll with up or down buttons to view options, then select by pushing Next.
Here are the items in this menu:
TYPE — Set to SOFTENING DN POST
BACKWASH TIME — Set to 8 or any preferred backwash duration.
DRAW DN TIME – Leave it at 60 minutes.
BACKWASH TIME — This is the second backwash. Set at 8 or any other preferred duration.
RINSE TIME — Duration of Rapid Rinse. 8 minutes recommended.
FILL — Here you enter the total pounds of salt the unit will use for the regeneration. You determine this by multiplying the cubic feet of resin in the softener by 15. For example, if you have a 12″ diameter softener it has 2 cubic feet of resin, so you would put 30 lbs. in FILL. The programming suggested here is for full salt usage. You can program the unit to use less salt, but other changes will need to be made. Get advice if needed.
GRAINS OF CAPACITY. Use these numbers for residential tank sizes.
8″ Tank = 22,500
9″ Tank = 30,000
10″ Tank = 45,000
12″ Tank = 60,000
These numbers are for “full salt” settings. For larger units or for reduced salt, get advice.
GALLONS CAPACITY = AUTO. Auto means that the softener will figure it out based on the information you have given it.
REGEN = DELAYED. This means that the softener will regenerate at the regeneration time you have selected.
RELAY 1, RELAY 2, SERVICE ALARM= OFF.
Next enter the USER PROGRAMMING MENU by pressing simultaneously and holding NEXT and DOWN for five seconds.
WATER HARDNESS– Enter the hardness of your water, in GRAINS PER GALLON.
DAY OVERRIDE — This is the number of days between regenerations in the event that the metered amount is not reached. In most cases, the default is a good selection.
REGENERATION TIME= This is the time of day or night when the regeneration will occur. If you have more than one treatment device, like a backwashing filter, make sure they don’t conflict. First set the hour, then NEXT will let you set the minutes.
LIGHT NORMALLY: OFF. (The light will come on if you touch a button.)
When the unit returns to the time-of-day screen, scroll through the settings from the time-of-day screen by using the NEXT key. You’ll see CAPACITY REMAINING in gallons, the total gallons it will count down before regeneration, REGENERATION IN= based on the value that you selected as DAY Override, and FLOW RATE = 0.
