4. Description of function
4.1. Meter regeneration
In normal use the LCD display alternates between following
indications:
• Time of day
• Remaining capacity (m
3
)
•Flow rate
• Number of days until next regeneration
• Installer name
• Softener name.
At the time of regeneration the controller compares the remai-
ning capacity with the reserve and decides if it is necessary to
start the regeneration. KS20S softener is equipped with a
blending device to insure a residual hardness in softened
water.
Controller
During regeneration the LCD display alternates between
following indications:
• Cycle number
•Cycle name
• Remaining time for the current cycle.
When all the cycles are finished, the valve comes back to the
service position.
The controller of KS20S softener can manage:
• Normal brining
• Proportional brining
• Counter current regeneration (upflow ).
4.2. Valve operation
The bypass valve of KS20S softener can be set in different
positions (see 7.2. Valve positions):
• Normal operation
• Bypass
• Diagnostic bypass
• Shut off.
Setting Mode
To enter the program mode put the valve to the normal opera-
tion position. During and after the setting (see 8. Setting), the
valve will continue to operate normally monitoring all informa-
tion. The settings are stored in permanent memory.
Power failure
During a power failure the controller of KS20S softener will be
inoperative and any calls for regeneration will be delayed.
The controller will continue normal operation from the point of
interruption once the power supply is resumed.
All control displays and programming will be stored during a
power failure for a later use when the power supply is
resumed. The control will retain these values without loss, if
necessary, for years.
4.3. Application
Honeywell recommends the following applications of KS20S
softener:
Type Size Honeywell recommendations

Note! Values recommended for households with a
water hardness of 30 f°H and an average daily
consuption of 0,1 m3 water per person.
Note! Honeywell recommends to install a 100µ-
cartridge filter.
