El esquema no tiene en cuenta la eventual acción del tiempo complementario y presupone que la salida proporcional del l ventilador (

V FAN

) esté 

configurada para acción directa (

P07

=0) y señal 0..10V (

P33

=0; 

P34

=100).

 

La salida proporcional del ventilador se apaga siempre (0V) cuando la salida de la válvula, 

OUT COOL

 o 

OUT HEAT

, está apagada (caso non visible 

en el esquema).

Abb. 7

: Das Schema zeigt die Steuerung der Ventile in einer Anlage mit 4 Rohren mit neutralem Bereich. Analog dazu wird der Ausgang des Warmventils in 

einem System mit 2 Rohren gleich gesteuert. In diesem Fall entspricht die 

Ts

 (Setpointtemperatur) der 

Ts ris

 im Winter und der 

Ts raf

 im Sommer. 

 

Das Schema berücksichtigt nicht die mögliche Wirkung der Zusatzzeit und setzt voraus, dass der proportionale Ausgang des Ventilators (

V FAN

) für 

eine direkte  Betätigung (

P07

=0) und für ein Signal 0..10V (

P33

=0; 

P34

=100) konfiguriert ist.

 

Der proportionale Ausgang des Ventilators wird immer ausgeschaltet (0V), wenn der Ausgang des Ventils, 

OUT COOL

 oder 

OUT HEAT

ausgeschaltet ist (Fall, der auf dem Schema nicht ersichtlich ist).
