4.1.5 Dip switch e tipo installazione
Nel caso di impianto 4 tubi le valvole batteria principale e supplementare non sono
mai aperte contemporaneamente e la resistenza è disabilitata.
Impianti ibridi: 4 Tubi con anello locale a 2 tubi
Nelle confi gurazioni ibride (4 tubi con anello locale a 2 tubi) il funzionamento è
regolato dai seguenti parametri, (vedi esempio seguente).
• Valvola acqua fredda/ acqua calda: aperte se la temperatura ambiente non ha
raggiunto il set point. Le valvole acqua calda e acqua fredda non sono mai aperte
contemporaneamente;
• Valvola locale: aperta quando viene attivata le valvola dell’acqua calda o fredda;
chiusa quando non ci sono valvole attive;
• Pompa di circolazione: attiva quando sono aperte le valvole di acqua calda o fredda.
4.1.5 Dipswitches and type of installation
In the case of 4 pipe installations, the main and secondary coil valves are never
open at the same time, and the heater is disabled.
Hybrid systems: 4 pipe with local 2 pipe loop
In hybrid confi gurations (4 pipe with local 2 pipe loop) operation is set using the
following parameters (see the example below).
• Cold water/ hot water valve: open if the room temperature has not reached
the set point. The hot and cold water valves are never open at the same time;
• Local valve: open when the hot or cold water valve is activated; closed when
no valves are active;
• Circulating pump: on when the hot or cold water valve is open.
