Fig. 14: Lo schema mostra il pilotaggio delle valvole in un impianto a 4 tubi con zona neutra. Lo schema presuppone uscite congurate per azione propor-
zionale diretta 0..10V e non tiene conto dell’eventuale azione del tempo integrativo. 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 ris in inverno e Ts raf in estate.
The scheme shows the valve control in a 4-pipes 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. Likewise a 2-pipes system valve output (heating valve output)
would be driven at the same way, in this case Ts (set-point temperature) would coincide with Ts hea when in heating mode and Ts coo when in
cooling mode.
