• To program the regenerant amount, press SET to enter the change
mode. The 110 (g/l) default will begin to flash. Use UP and
DOWN to scroll through the available settings. Press SET to enter
the amount.
• Filter backwash time (filter mode only)
If the system is set up as a filter, regenerant amount is unnecessary.
The controller deactivates the regenerant amount setting, and
changes to an adjustable backwash time in minutes.
• Press SET to change the time.
• The default time of 14 minutes will begin to flash.
• Use UP and DOWN to select the appropriate backwash time for
the media type and amount used. The controller can use 0 to
99 minutes for backwash.
• Press SET again to enter that time.
Step 8: Estimated Capacity
• System capacity is displayed in total kilograins or kilograms of
hardness removed before a regeneration is necessary.
• Value is derived from the system's resin volume input, and salt
amount input.
• The capacity displayed is a suggested value – as recommended
by resin manufacturers.
• Capacity is only displayed for information purposes on 742
control – it cannot be changed.
• To change capacity on 762 control, press SET to make the default
capacity flash. Use the UP and DOWN buttons to increment to
the desired capacity.
• Press SET to accept the setting and advance to the next parameter.
• FA filters: see section on capacity, Setting the 700 for 5-Cycle
Filter Applications.
If using the 742 control, programming is complete. The control will
return you to the normal operation mode.
