1.4 Adjustments

Heating temperature setting

To set the system flow temperature, use the CH push buttons (part. 3 and 4 - fig. 1). It can be varied from a minimum
of 20°C to a maximum of 90°C.

Domestic hot water temperature setting

To set the hot water temperature, use the DHW push buttons (part. 1 and 2 - fig. 1). It can be varied from a minimum of
40°C to a maximum of 55°C.

Room temperature adjustment (using a room thermostat)

Using the room thermostat, set the temperature desired. Controlled by the room thermostat, the boiler lights and heats
the system water to the system delivery setpoint temperature. The burner shuts down when the desired temperature in
the room is reached.

A

A room thermostat and programmer are a mandatory requirement (Building regulations Doc ‘L’ 2002).

Room temperature adjustment (using an optional Remote Control)

Using the remote control, set the temperature desired. The flow temperature will be controlled by the remote control.
For settings and other informations, see the relative manual.

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 the CH push buttons (part. 3 and 4 - fig. 1) is possible to set the maximum flow temperature for the installation.
