3.6 Connection to the flue
The unit must be connected to a flue designed and built in compliance with current reg-
ulations. The pipe between the boiler and flue must be made from material suitable for
the purpose, i.e. heat and corrosion resistant. Ensure the seal at the joints and insulate
the entire pipe between boiler and flue, to prevent the formation of condensate.
4. SERVICE AND MAINTENANCE
All adjustment, conversion, startup and maintenance operations described below must
only be carried out by Qualified Personnel (meeting the professional technical require-
ments prescribed by current regulations) such as those of the Local After-Sales Techni-
cal Service.
LAMBORGHINI declines any liability for damage and/or injury caused by unqualified and
unauthorised persons tampering with the unit.
4.1 Adjustments
TEST mode activation
Press the heating buttons (details 3 and 4 - fig. 1) together for 5 seconds to activate the
TEST mode. The boiler lights at the maximum heating power set as described in the fol-
lowing section.
The heating symbol (detail 25 - fig. 1) and DHW symbol (detail 13 - fig. 1) flash on the
display.
fig. 18 - TEST mode (heating power = 100%)
To deactivate the TEST mode, repeat the activation sequence.
The TEST mode is automatically disabled in any case after 15 minutes.
Burner adjustment
Boiler efficiency and correct operation depend above all on accurate burner adjustments.
Carefully follow the Manufacturer's instructions. The two-stage burners must have the
first stage adjusted to a power level not below the boiler's rated min. power. The power
of the second stage must not be higher than the boiler's rated max. power.
User interface
The user interface is developed on display cards DSP05, DSP06 or DSP08, which com-
municate with card DBM09A via a flat cable.
If replacing the card DBM09A, in order to manage the display card DSP08, a parameter
must be changed.
This occurs by pressing the Heating+ and Summer/Winter buttons together for 5 sec-
onds.
Service Menu
The card is equipped with two Menus: one for configuration and the other defined Serv-
ice.
The configuration Menu is accessed by pressing the DHW buttons together for 10 sec-
onds. Only one parameter modifiable only from card for security reasons is available.
