I : Cırcuıt breaker closed (On ), O : Cırcuıt breaker open (Off )

If Aux. contact of MV C.B. is open, related L.V. C.B. can not be closed.

Automatic operation : ( Selector switch is in Auto. Position.)

1- All circuit breakers are inserted and open. If Undervoltage relays show Voltage U > % 90* Un ( 380 V ) under CB #1 and CB #2, trip contacts of these relays are open.
Since there is no voltage on main busbar of switchboard, trip contacts of undervoltage relays which are located two sides of bus tie C.B. are closed.

2- If trip contacts of CB #1 and CB #2 are open, it means that there is no fault occurred before. After a time delay ( 2 s. ), CB #1 & CB #2 C.B.,s will be closed.

3- When there is a voltage fault over INCOMING #1 measured by respective undervoltage relay and there is confirmation of voltage in the other line, CB #1 will be open. After a time delay ( 2 s. ) , TIE CB will be closed.

When CB #1 is either test or disconnected position, TIE CB will be closed after a time delay ( 2 s. ), regardles of voltage presence over INCOMING #1.

If CB #1 has been open due to trip , TIE CB can not be closed unless problem is solved.
If CB #1 opens because of aux. supply fault, TIE CB will be closed after a time delay ( 2 s. ), regardles of voltage presence over INCOMING #1.

4- When there is a voltage fault over INCOMING #2 measured by respective undervoltage relay and there is confirmation of voltage in the other line, CB #2 will be open. After a time delay ( 2 s. ) , TIE CB will be closed.

When CB #2 is either test or disconnected position, TIE CB will be closed after a time delay ( 2 s. ), regardles of voltage presence over INCOMING #2.

If CB #2 has been open due to trip , TIE CB can not be closed unless problem is solved.
If CB #2 opens because of aux. supply fault, TIE CB will be closed after a time delay ( 2 s. ), regardles of voltage presence over INCOMING #2.

Manuel operation : ( Selector switch is in Man. Position.)

1- All circuit breakers are inserted and open.
2- CB #1 and CB #2 can be closed by pressing related pushbuttons.

3- When there is a voltage fault over INCOMING #1 and there is confirmation of voltage in the other line, CB #1 can be open by pressing related pushbutton.
After opening CB #1, TIE CB can be closed by pressing pushbutton.
If CB #1 has been open due to trip, Fault signal should be observed and the reason which caused this trip should be investigated. TIE CB can not be closed unless trip signal is resetted.

4- When there is a voltage fault over INCOMING #2 and there is confirmation of voltage in the other line, CB #2 can be open by pressing related pushbutton.
After opening CB #2, TIE CB can be closed by pressing pushbutton.
If CB #2 has been open due to trip, Fault signal should be observed and the reason which caused this trip should be investigated. TIE CB can not be closed unless trip signal is resetted.

ELFOSystem BUILDING es la instalación única e inteligente de energía renovable para los edificios plurifamiliares y comerciales.

Equipada con todos los elementos que crean el confort ideal durante todo el año, garantiza la calefacción, la climatización, la producción de agua sanitaria caliente, y la renovación y purificación del aire con una eficiencia total sin parangón en el mercado.

ELFOSystem BUILDING se basa en los siguientes componentes:

- El centro del sistema es ELFOEnergy Ground Medium, la nueva bomba de calor geotérmica de elevada eficiencia para producir calor y frío, así como agua sanitaria caliente. Dotada de tecnología modular scroll, es ideal para las cargas parciales. La válvula de expansión electrónica y los intercambiadores de calor de elevadas prestaciones, garantizan la máxima eficiencia de intercambio, permitiendo a ELFOEnergy Ground Medium alcanzar la Clase A, según Eurovent, tanto en calefacción como en aire acondicionado. ELFOEnergy Ground Medium es una central térmica pre-ensamblada, que simplifica la instalación y disminuye las dimensiones totales un 70% respecto a las soluciones tradicionales, además de garantizar una fiabilidad total. Las múltiples configuraciones, la compactibilidad y la modularidad convierten a ELFOEnergy Ground Medium en la solución ideal para cualquier aplicación que necesite mucha potencia.

Para las viviendas unifamiliares de nueva construcción, Clivet propone al mercado la solución ELFOSystem GAIA Edition, un sistema completo de ciclo anual para la calefacción, la climatización, la renovación y purificación del aire, y la producción de agua caliente sanitaria basado exclusivamente en la tecnología de la bomba de calor que utiliza entre un 75 y un 100% de energía renovable.

Los elementos de ELFOSystem GAIA Edition han sido proyectados para generar un diálogo entre ellos, optimizar el uso de la energía y asegurar en todo momento la mejor eficiencia estacional. Prueba de ello son las instalaciones reales monitorizadas en nuevas construcciones, que demuestran como GAIA -la bomba de calor central del sistema Clivet- garantiza más del 75% de las necesidades de fuente renovable.
