• Calendar override
The controller can be programmed to regenerate automatically from a 1/2 day to a 99 day frequency.
The 1/2 day regeneration mode will regenerate at the “time of regeneration,” as well as 12 hours opposite from that time. For example, the controller will regenerate
at 2:00 AM and at 2:00 PM on the same day.
The default setting is 12 days. To change, push SET when this setting is displayed. Use the arrow buttons to increase/decrease. Push SET to enter the selection.
IMPORTANT NOTES
Setting days between regeneration to zero will cause the system to not regenerate. This setting is used for selecting regeneration on specifi c days or to use with
a remote regeneration input. See below.
Regeneration on specifi c day is used to provide regeneration when water demands are not steady. Example: If the weekdays have low usage and the weekend
is high, then regeneration every three days will not meet the requirements.
• Amount of salt used per regeneration
The controllers are setup to automatically calculate the capacity of the system by multiplying the resin/media volume that was entered earlier into the controller, with
the salt amount entered by the dealer/installer. This eliminates the need for salting effi ciency tables.
The default setting is L (Low Salt).
To enable the most simple programming possible, the dealer/installer has three salt amount options to choose from. These are set up to give the installation the
maximum performance based on the inputs by the dealer/installer. The three salt options are:
High Salt — This setting gives the installation the highest capacity possible for that resin volume. This is a great setting for applications with very high hardness,
many occupants or for applications where the dealer wants to provide that the application supplies soft water. This setting may tend to use less water over the
course of a year, because it generally needs to be regenerated less often. This setting is displayed as an “H”.
Standard Salt — This setting fi ts most applications around the world. It gives you an effi cient use of salt, while maintaining a large enough capacity to regenerate
every three days for most applications. This setting is displayed as an “S”.
Low Salt — This setting is provided to give your installation the maximum effi ciency of salt usage, as measured in grains of hardness softened per pound of salt used
(grains of CaCO
3
reduced per pound of salt used). This setting is useful for markets where highly effi cient conditioners are expected or required by the consumers
or law. This setting is displayed as an “L”.
IMPORTANT NOTE
SODIUM INFORMATION: Water softeners using sodium chloride for regeneration add sodium to the water. People who are on sodium restricted diets
should consider the added sodium as part of their overall sodium intake.
