Economy/Comfort selection
The unit is equipped with a special internal device that ensures a high hot-water delivery speed and excellent user com-
fort. When comfort mode is active the water in the boiler is maintained at a pre-determined temperature, which means
that hot water is available at the boiler outlet as soon as a tap is opened, ie with no waiting.
The user can turn the device off (ECO mode) by pressing economy/comfort button (part.7 - fig. 1).
In ECO mode the display shows the relevant symbol (part. 12 - fig. 1). To turn on COMFORT mode, press economy/
comfort button (part. 7 - fig. 1) again, the ECO symbol will vanish from the display.
Outside temperature compensation
When the (optional) external sensor kit is fitted to the appliance, the system can work in Outside Temperature Compen-
sation mode. In O.T.C. mode the temperature of the heating system is controlled according to the external climate con-
ditions, this will guarantee a high degree of comfort and energy saving all year round.
By using the CH buttons (part. 3 and 4 - fig. 1) it is possible to set the maximum flow temperature for the installation.
