4.1. Meter regeneration
In normal use the LCD display alternates between following
indications:
• Time of day
• Remaining capacity (m3)
•Flowrate
• Number of days until next regeneration
• Installer name
• Softener name.
Atthetimeofregenerationthecontrollercomparestheremai-
ningcapacitywiththereserveanddecidesifitisnecessaryto
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
•Cyclename
• Remaining time for the current cycle.
Whenallthe cycles are finished,thevalvecomesbackto 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
Toentertheprogram modeputthevalvetothenormalopera-
tion position. During and after the setting,the valve will cont-
inue to operate normally monitoring all information. The
settings are stored in permanent memory.
Power failure
DuringapowerfailurethecontrollerofKS20Ssoftenerwillbe
inoperative and any calls for regeneration will be delayed.
Thecontrollerwillcontinuenormaloperationfromthepointof
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

KS20S-55 18 liters 3-8 family dwelling
KS20S-85 25 liters 6-21 family dwelling
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 toinstall a 100µ-
cartridge filter.

Honeywell GmbH 4 MU1H-1419GE23R1504
4.4. Sodium concentration limit
When operating a KS20S softener, the limit value for the
sodium concentration (acc. drinking water ordinance) of
200 mg/l may not be exceeded.
To reduce the water hardness by 1 °fH, add about 4,5 mg/l
sodiumto thewater. Additionally,takeintoaccountthe basic
sodium content of the raw water. The maximum possible
softening results from these values.

Componenti principali
Img. 1 Componenti principali di KS20S
L'addolcitore d'acqua KS20S consiste nei seguenti compo-
nenti principali:
1. Controller
2. Coperchio del serbatoio di salamoia
3. Copertura principale

4. Descrizione del funzionamento
4.1. Rigenerazione tramite contatore
Durante la modalità di funzionamento normale sul display
LCD vengono visualizzati i seguenti parametri in sequenza:
• Ora del giorno
• Capacità residua (m3)
• Portata
• Numero di giorni fino alla rigenerazione successiva
• Nome dell'installatore
• Nome dell'addolcitore d'acqua.
Al momento stabilito per la rigenerazione il controller
confronta la capacità residua con la riserva e decide se è
necessario avviare la rigenerazione. L'addolcitore d'acqua
KS20S è dotato di un dispositivo di miscelazione che garan-
tisce un determinato grado di durezza residua dell'acqua
addolcita..
Controller
Durante la rigenerazione sul display LCD vengono visualiz-
zati i seguenti parametri in sequenza:
• Numero del ciclo
• Nome del ciclo
• Tempo rimanente del ciclo in corso.
Quando tutti i cicli sono terminati, la valvola torna nella posi-
zione di servizio.
Il controller dell'addolcitore d'acqua KS20S è in grado di
gestire le seguenti funzioni:
• Addolcimento normale
• Addolcimento proporzionale
• Rigenerazione controcorrente (upflow).
4.2. Funzionamento della valvola
La valvola di bypass dell'addolcitore d'acqua KS20S può
essere impostata in diverse posizioni (vedere 7.2. Posizioni
della valvola):
• Funzionamento normale
• Bypass
• Bypass diagnostico
• Intercettazione.
Modalità di configurazione
Per accedere alla modalità di configurazione, mettere la
valvola in posizione di funzionamento normale. Durante e
dopo la configurazione (vedere 8. Configurazione) la valvola
continua a funzionare normalmente monitorando tutte le
informazioni. Le impostazioni vengono conservate nella
memoria permanente.
