> MAXIMISING COMFORT AND SAVINGSROMEO REMOTE CONTROLDIVATECH D can be used with a wide range of remote controls and timers for managing the operation of the appliance. The ROMEO remote control series features four models, allowing programming of weekly or daily comfort conditions, and the possibility to choose wired or wireless connection. ROMEO adopts Opentherm® communication protocol. ThemodulatingfunctionontheROMEO ensures gradual adjustment of boiler output as the room temperature approaches the setpoint. This improves the quality of comfort, avoiding temperature fluctuations in the rooms.

ROMEO’SFUNCTIONS
An optional outdoor probe can be easily connected to the boiler’s wiring.The microprocessor compares external and internal temperatures and increases or decreases central heating flow temperature accordingly, maximising efficiency and allowing extra savings. The adaptation curve slope can be set among 10 possible solutions, thus deciding the ratio of flow temperature variation according to the outside climatic conditions.
El ahorro energético
> LA FUNCiÓN “SUN eASY”FERDIGIT MICRO se ha diseñado para que se integre con facilidad en las instalaciones realizadas con las tecnologías más recientes. El sistema SUN EASY, de serie en la caldera, está dotado de una electrónica que simplifica la unión con los paneles solares tanto de circulación natural como forzada. Mediante un sensor, situado en el circuito del agua sanitaria, controla, de modo continuo, la temperatura del agua procedente de los paneles solares, previendo el encendido del quemador sólo en caso de que ésta última se sitúe por debajo del nivel necesario para garantizar el confort óptimo al usuario.

CALderA trAdiCiONAL
> eL SiSteMA Air CONtrOLEl circuito de aire FERDIGIT MICRO utiliza un sistema modulante formado por un ventilador de caudal variable, controlado por el transductor de presión y dirigido por el microprocesador de la tarjeta electrónica. AIR CONTROL permite suministrar la cantidad justa de aire necesaria para la combustión en cada una de las condiciones de funcionamiento del generador, garantizando eficiencia allí donde las calderas tradicionales carecen de ella. Efectivamente, a lo largo del año, para un generador que funciona la mayor parte del tiempo al 30 - 50% de su potencia, es decir en las condiciones en las que una caldera con ventilador ON-OFF funciona con menor eficiencia, el sistema AIR CONTROL de FERDIGIT MICRO consigue ofrecer de todas maneras el máximo rendimiento.
El Kit sonda exterior se conecta directamente a la caja de conexiones de la caldera
Con la instalación del kit “SONDA EXTERIOR” se puede hacer funcionar la caldera en temperatura variable. Esto significa que sin actuar sobre las teclas de regulación de la temperatura de la instalación, la caldera se autorregula en función de las variaciones de las temperaturas exteriores. Ello se traduce en un ahorro energético garantizando al mismo tiempo el máximo confort al usuario.

DIVATECH D> > > Heating Division
DIVATECH D boasts an electronic that simplifies the integration with thermal solar sytems, both natural and forced circulation.The microprocessor monitors water temperature coming from solar circuit through the DHW sensor and ignites the burner only in case it is necessary. In such a case the boiler releases only the necessary heat to DHW which had already pre-heated by collectors, in order to reach the setpoint required by the user, allowing at the same time considerable savings even during cooler seasons.

FUNCTION
> ANTIFREEZEAlso in standby-mode, in case the temperature in the boiler drops to 5°C (temperature detected by CH or DHW sensor), the burner is automatically ignited at the minimum output and pump is also switched on. Thereby the appliance is protected against damages caused by frost. This function is active when the boiler is gas and power supplied.
> ANTI-BLOCK FUNCTIONPump is automatically switched on approximately for 5 seconds, after 24 hours of inactivity. This protection schedule is applied also for diverting valve. Such precaution avoids block of the mentioned devices in case of long inactivity.
> POST-CIRCULATIONThis function permits to recover all heat stocked for thermal intertia in the central heating exchanger and transfer it to the heating system, and as a consequence to the rooms. It is a timed function (with customisable span) and is active after burner switches off in heating mode.
> FUNCTIONS
> EVOLVED COMBUSTION SYSTEM Innovative combustion control which ensures the best operation at the different conditions of thermal load and draught (“F” forced flue model). The combustion set has been carefully designed as a synergic group, in order the components interact together, under the supervision of the control board.
