Schaltverhalten "2P" (Zweipunktregler),  
Reglertyp "PI" (PI-Regler)  
 
Für die Schaltpunkte S1 und S2 werden 
jeweils -wie oben beschrieben- die Soll-
werte eingegeben. Statt der Hysterese 
wird jeweils der zugehörige Regelparame-
tersatz eingestellt.  
Der Wertebereich der Regelparameter 
reicht von 1 („hart“) bis 8 („weich“). 
Beide Schaltpunkte arbeiten voneinander 
unabhängig.  
 
Schaltverhalten "3P" (Dreipunktregler),  
Reglertyp "I  0" (Ein/Aus)  
 
Der Schaltpunkt wird in Form eines ge-
meinsamen Sollwertes mit positiver 
Hysterese H1 f. Evakuierung bzw. negati-
ver Hysterese H2 f. Belüftung eingestellt.  
Die Hysteresen liegen asymmetrisch zum 
Sollwert. Bei Änderung des Sollwertes 
werden die Hysteresen zunächst automa-
tisch über einen prozentualen Zusam-
menhang an den neu eingegebenen 
Sollwert adaptiert. Eine anschließende 
manuelle Änderung der Hysteresen ist 
ebenfalls möglich (Werte werden dabei 
auf Plausibilität zum Sollwert überprüft).   
 
Beispiel:  Sollwert    S = 100mbar 
 

Hysterese H1 = 10mbar  

 

Hysterese H2 = 20mbar 

 

Relais für Evakuierung  wird bei 100mbar 
deaktiviert und bei 110mbar aktiviert. 
Relais für Belüftung wird bei 100mbar 
deaktiviert und bei 80mbar aktiviert.  

Switching Mode "2P" (On/Off),  
Controller Type "PI" (with PI-feedback)  
 
For switchpoints S1 and S2 the setpoints 
are adjusted as described above. Instead 
of hysteresis, the corresponding set of PI-
parameters is selected. 
Parameter range is 1 ("hard") to 8 ("soft"). 
Both setpoints operate independently 
from each other.  
 
 
 
Switching Mode "3P" (tri state),  
Controller Type "I  0" (without feedback)  
 
The switchpoint is adjusted by one com-
mon setpoint with a positive hysteresis H1 
for evacuation and a negative hysteresis 
H2 for aeration.  
The two hysteresis lie asymmetrical 
around the setpoint.  When the setpoint is 
changed, the hysteresis are adapted 
automatically using a constant percentage 
ratio. Afterwards a manual adjustemt of 
the new hysteresis is, of course, possible 
(values are checked according to plausi-
bility). 
 
 
Example: setpoint     S = 100mbar 
 

hysteresis H1 = 10mbar  

 

hysteresis H2 = 20mbar 

 

Relais for evacuation is switched off at 
100mbar and switched on at 110mbar. 
Relais for aeration is switched off at 
100mbar and switched on at 80mbar. 

Mode de commutation "2P" (deux points), 
régulateur de type "PI" (Régulateur PI) 
 
Régler les valeurs de consigne des points 
de commutation S1 et S2 comme indiqué 
ci-dessus. Au lieu de l’hystérèse, on 
définit pour chaque point un jeu de para-
mètres de réglage. La plage de valeurs 
des paramètres de réglage s’étend de 1 
("dur") à 8 ("mou"). Les deux points de 
commutation fonctionnent indépendam-
ment l’un de l’autre.  
 
Mode de commutation "3P" (trois points), 
régulateur de type  "I 0" (Entrée/Sortie) 
 
Le point de commutation est réglé sous 
forme d’une valeur de consigne commune 
avec hystérèse positive H1 p. l’évacuation 
ou négative H2 p. la ventilation. Les 
hystérèses sont asymétriques par rapport 
à la valeur de consigne. En cas de modi-
fication de la valeur de consigne, les 
hystérèses sont automatiquement et 
instantanément adaptées à la nouvelle 
valeur de consigne suivant un rapport de 
pourcentage. Il est également possible de 
régler manuellement les hystérèses (la 
plausibilité des valeurs par rapport à la 
valeur de consigne est alors vérifiée). 
Exemple: Val. de consigne S = 100mbar 
 

Hystérèse H1 = 10mbar  

 

Hystérèse H2 = 20mbar 

 

Le relais d’évacuation est désactivé à 
100 mbar et activé à 110 mbar.   
Le relais de ventilation est désactivé à 
100 mbar et activé à 80 mbar.
