PILOTAGGIO USCITE - OUTPUT DRIVING - PILOTAGE DES SORTIES - PILOTAJE SALIDAS
Lo schema mostra il pilotaggio delle valvole in un impianto a 4 tubi con zona
neutra. Lo schema presuppone uscite congurate per azione proporzionale
diretta 0..10V e non tiene conto dell’eventuale azione del tempo integra-
tivo. Analogamente l’uscita valvola di un sistema a 2 tubi (uscita valvola
caldo) verrà pilotata allo stesso modo, in questo caso la Ts (temperatura di
setpoint) coinciderà con Ts hea in inverno e Ts coo in estate.

The scheme shows the valve control in a 4-pipe unit with neutral zone. In
the diagram it is assumed that outputs are congured for proportional direct
action (0..10V) and that any integrative action is not taken into account. Li-
kewise a 2-pipes system valve output (heating valve output) would be driven
at the same way, in this case Ts (knob set-point temperature) would coincide
with Ts hea when in heating mode and Ts coo when in cooling mode.
Le schéma montre le pilotage des vannes d’une installation à 4 tubes avec
zone neutre. Le schéma présuppose des sorties prédisposées pour action
proportionnelle directe 0..10V et ne tient pas compte de l’éventuelle action
du temps intégratif. La sortie vanne d’un système à 2 tubes (sortie vanne
chaud) sera pilotée de la même façon et, dans ce cas, la Ts (température de
setpoint) coïncidera avec Ts hea en hiver et Ts coo en été.
El esquema muestra el manejo de las válvulas en una instalación a 4 tubos
con zona neutra. El esquema presupone salidas conguradas para accione
proporcional directa 0..10V y no tiene en cuenta la eventual acción del
tiempo complementario. Análogamente la salida válvula de un sistema a
2 tubos (salida válvula calor) será manejada del mismo modo, en este caso
la Ts (temperatura de setpoint) coincidirá con Ts hea en invierno y Ts
coo en verano.
