INSTALLATION AND START-UP
Remove the control unit base-block by levering the two lower hooks (fig. 1).
Fix the control unit to the wall via the holes in the base-block. This should be mounted 1.5 m above the floor in an area well away from entry/exit doors, windows or other factors that might influence room temperature readings (fig. 2). After making sure that electrical power at the boiler is OFF proceed with the electrical connections using bi­polar wiring: do not route the wiring parallel to the main power supply wires/leads. If it is not possible to avoid taking the same wiring route use a shielded lead, the braid of which must be connected to an earth. Connect the lead extremities to the ”+IN+” terminal block (fig. 3). It is highly important that you observe the indicated polarities (boiler + to control +, boiler – to control -) Lead length must not exceed 50 m.

The boiler allows to adapt the heating thermal power (without involving the adjustment of the capacity available for the production of hot water) to the thermal need of the rooms to be heated. When leaving the factory all boilers are set to 70% of their maximum output. To adapt the boiler to the thermal power needed by the plant it is necessary to carry out the following operations:
Insert a manometer in the pressure tube (G)
Electrically feed the gas valve with the boiler on in the WINTER position
Adjust the heating potentiometer (1) located on the modulation card until the gas pressure required by the
heating system capacity is reached (see pressure curves).
Should it be necessary to adjust the minimum and maximum regulation of the gas valve (preset at the factory) for the hot water supply, following operations should be carried out:
remove the power supply contacts from the coil (E).
power the gas valve with the boiler on in the SUMMER position and bleed off domestic hot water at the
maximum flow rate (13 litres/min).
turn the adjustment screw (D) all the way down without using any tools.
loosen the locknut (B)
use a wrench to turn the coil screw (A) until maximum gas pressure (values are given on page 43) is
reached.
tighten the locknut (B).
undo the adjustment screw (D) until minimum gas pressure (values are given on page 43) is reached.
reconnect the coil (E).
This task sets the boiler so that it suits the needs of the user.
NOTE: To carry out this adjustment it is necessary to use a water-column pressure gauge, connecting it to the pressure outlet (G).

GENERAL INSTRUCTIONS
This booklet constitutes an integral and essential part of the product and should be preserved for any further consultation. Read carefully the instructions contained in this booklet as they provide important directions regarding the operation of the appliance, allowing a great saving in its use and maintenance.
If the appliance is sold or transferred to other people or if you move house and leave your apartment, ensure that the manual remains with the appliance so that it can be used by the new owner.
This appliance should be destined only for the use for which it has been expressly envisaged. Any other use is to be considered improper and therefore dangerous. The manufacturer cannot be considered responsible for any damages caused from improper, erroneous or unreasonable use.
Do not touch the parts of the boiler which during the operation become overheated. These parts can be dangerous for children or inexperienced persons.
Do not obstruct the inlet or dissipation screens.
Do not make the boiler wet with splashes of water or other liquids.
Do not rest any object upon the boiler.
Use of the boiler is prohibited for children or the inexperienced.
Do not carry out any cleaning of the boiler with inflammable substances.
Do not deposit containers of inflammable substances in the location where the boiler is situated.
In the presence of the risk of freezing suitable provisions must be taken which are not however the concern
of the boiler manufacturer
As the boiler has hot spots it is forbidden to leave any object which might explode when exposed to heat.
ALL INSTALLATION, MAINTENANCE AND GAS CONVERSION OPERATIONS MUST BE CARRIED OUT BY AUTHORISED SKILLED TECHNICIANS.
To ensure that boiler is installed correctly and that it functions properly, we recommend that only Lamborghini accessories and spare parts be used.

CHECKS AND MAINTENANCE
Before starting up the boiler ask qualified personnel “LAMBORGHINI SERVICE to check:
a) that the data on the information plate corresponds to that required by the gas, electrical and water
supply networks;
b) that the pipes which branch off from the boiler are lined with suitable thermally-insulated sheathing; c) the proper functioning of the flue pipe; d) that the comburent air flow and the fumes evacuation take place properly in accordance with the
regulations in force;
e) that correct aeration and maintenance are possible in case of installation in the furniture.
Ensure that the installer has connected the boiler safety discharge to a waste. In the case of the contrary the intervention of the safety valves could flood the premises and the manufacturer would not be held responsible for this.
Ensure that the piping of the installation is not used as an earth outlet for other installations; beyond not being ideal for such a use it could in short bring serious damage to the other appliances connected to it.
Ask qualified personnel “LAMBORGHINI SERVICE to check:
a) the internal and external tightness of the gas system; b) that the gas delivery is that required by the boiler output; c) that the type of gas is suitable for the boiler; d) that the pressure of gas supply is within the values stated on the boiler plate; e) that the gas installation is the correct size and equipped with all the safety and checking devices
prescribed by the current regulations.
Ask periodically to check the proper functioning and the good state of the flue exhaust.
Ensure that the electrical system has been confirmed by qualified personnel to be adequate for the power
required by the appliance itself.
The electricity supply cable must not be replaced by the user, but by qualified personnel only.
The electrical safety of the appliance is attained only if the same has been connected to an effective system
earthed in accordance with the current regulations. The verification of this fundamental prerequisite should be made by qualified persons as the manufacturer will not be responsible for damage caused by the lack of adequate earthing of the installation.

INSTALLER SETTINGS
The tasks in this section must only be carried out by qualified personnel. Carrying out these procedures wrongly may damage the control unit and boiler or cause them to malfunction.
CONNECTING UP TO THE OUTDOOR TEMPERATURE SENSOR.
The control unit can also be fitted with a sensor that monitors outdoor temperature. The outdoor temperature reading utilised by the control unit may be supplied in one of two different ways:
- when the outdoor temperature sensor is connected to the boiler the temperature reading is sent from
the boiler to the control unit.
- when the outdoor temperature sensor is connected directly to the control unit the reading is acquired
and processed by the control unit directly. If both are present the local sensor is ignored and the outdoor sensor connected to the boiler base is utilised. This situation is highlighted by the appearance of error message E67. To connect the outdoor sensor to the control unit use the S.EXT connection on the terminal block.
With the outdoor sensor connected, pressing the key shows the outdoor temperature and heating water temperature.
ENABLING REMOTE OPERATION
The control unit has an input (TEL + and -) which allows connection of an optional control unit for distance operation. Operating mode:
- TEL input open
The control unit operates as described in the handbook.
- TEL input closed The control unit switches to remote mode, that is: heating and hot water functions enabled, automatic temperature regulation according to timer programme with on-display information while upper display shows the TEL message in place of room temperature. This mode persists until the user disables it by acting on the remote mode switch (TEL input open). Standard operating mode is then restored.
CLOCK SPEED CORRECTION
Allows you to improve clock precision by increasing speed (should it run slow) or decreasing speed (should it run fast). The entire correction procedure must be done with the control unit powered and connected to the boiler. Clock correction: Press key R and keep it pressed. Press the H/Day key Release the R key and wait for the display to show the Hour confirmation message. The next two stages must be done within 5 seconds otherwise the procedure will be aborted (a change of one unit alters clock speed by 30 seconds a year). Release the H/day key. Press the + key to increase clock speed (an increase of one unit speeds up the clock by 30 seconds a year). Press the – key to reduce clock speed (a decrease of one unit slows down the clock by 30 seconds a year). Wait 5 seconds after the last modification to exit this function and recommence normal operation.
