1. Operating instructions

1.1 Introduction

Dear Customer,

Thank you for choosing a LAMBORGHINIwall-mounted boiler featuring advanced design, cutting-edge technology,

high reliability and quality construction. Please read this manual carefully since it provides important information on safe

installation, use and maintenance.

NINFA 32 MC is a high-efficiency heat generator for heating and domestic hot water production, running on natural gas

or LPG, equipped with an atmospheric burner with electronic ignition and microprocessor control system, and designed

for installation indoors or outdoors in a partially protected place (in compliance with EN 297/A6) for temperatures as low

as -5°C (-15°C with optional antifreeze kit).

Indication during operation

Heating

A heating demand (generated by the Room Thermostat or Remote Timer Control) is indicated by lighting up of the ra-

diator (detail 5 - fig. 1).

The multifunction display (detail 9 - fig. 1) shows the heating sensor temperature.

fig. 2

Domestic hot water (DHW)

A DHW demand (generated by drawing domestic hot water) is indicated by lighting up of the tap (detail 6 - fig. 1).

The multifunction display (detail 9 - fig. 1) shows the DHW sensor temperature.

fig. 3

Comfort

A Comfort demand (restoring the temperature inside the boiler) is indicated by lighting up of the tap (detail 6 - fig. 1).

The multifunction display (detail 9 - fig. 1) shows the heating sensor temperature.

1.3 Turning on and off

Boiler not electrically powered

fig. 5 - Boiler not electrically powered

BThe antifreeze system does not work when the power and/or gas to the unit are turned off. To avoid damage

caused by freezing during long idle periods in winter, it is advisable to drain all water from the boiler, DHW

circuit and system; or drain just the DHW circuit and add a suitable antifreeze to the heating system, complying

with that prescribed in sec. 2.3.

Boiler lighting

Switch on the power to the unit.

fig. 6 - Boiler lighting

• For the following 120 seconds the display will show FH which identifies the heating system air venting cycle (AIR

PURGE function).

• During the first 5 seconds the display will also show the card software version.

• Open the gas cock upstream of the boiler.

• When the message FH disappears, the boiler is ready to operate automatically whenever domestic hot water is

drawn or in case of a room thermostat demand.

Turning the boiler off

Turn the selector (detail 3 - fig. 1) to 0.

fig. 7 - Turning the boiler off

33GB cod. 3540G380 - 02/2007 (Rev. 00)

When the boiler is turned off, the electronic board is still powered.

Domestic hot water and heating operation are disabled. The antifreeze system stays on.

To re-light the boiler, turn the selector (detail 3 fig. 1) to (winter) or (summer).

fig. 8

The boiler will be immediately ready to operate whenever domestic hot water is drawn or in case of a room thermostat

demand.

1.4 Adjustments

Summer/Winter changeover

Turn the selector (detail 3 - fig. 1) to (summer).

fig. 9

The boiler will only deliver domestic hot water. The antifreeze system stays on.

To deactivate Summer mode, turn the selector (detail 3 - fig. 1) to (winter).

Heating temperature adjustment

Operate the heating knob (detail 1 - fig. 1) to set the temperature between 30°C (min.) and 85°C (max.); it is advisable

not to operate the boiler below 45°C.

Domestic hot water (DHW) temperature adjustment

Operate the DHW knob (detail 2 - fig. 1) to set the temperature between 40°C (min.) and 55°C (max.);

fig. 11

Room temperature adjustment (with optional room thermostat)

Using the room thermostat, set the temperature desired in the rooms. If the room thermostat is not installed the boiler

will keep the heating system at its setpoint temperature.

Room temperature adjustment (with optional remote timer control)

Using the remote timer control, set the temperature desired in the rooms. The boiler unit will set the system water ac-

cording to the required room temperature. For information on the remote timer control, please refer to its user's manual.

ECO/COMFORT selection

The unit is equipped with a function that ensures a high domestic hot water delivery speed and maximum comfort for

the user. When the device is activated (COMFORT mode), the water contained in the boiler is kept hot, therefore en-

suring immediate availability of hot water from the boiler on opening the tap, thus avoiding waiting times.

The device can be deactivated by the user (ECO mode) by turning the selector (detail 3 - fig. 1) to the RESET position

for 2 seconds and then to (winter) or (summer). To activate COMFORT mode, turn the selector (detail 3 - fig. 1)

to RESET again for 2 seconds and then to (winter) or (summer).

Sliding temperature

When the optional outdoor sensor is installed, the boiler adjustment system works with "Sliding Temperature”. In this

mode, the temperature of the heating system is adjusted according outside weather conditions, in order to ensure high

comfort and energy saving throughout the year. In particular, as the outside temperature increases the system delivery

temperature decreases according to a determinate “compensation curve”.

With the Sliding Temperature adjustment, the temperature set with the heating knob (detail 1 - fig. 1) becomes the max-

imum system delivery temperature. It is advisable to set a maximum value to allow system adjustment throughout its

useful operating range.

The boiler must be adjusted at the time of installation by qualified personnel. Possible adjustments can in any case be

made by the user to improve comfort.

Compensation curve and curve shift

Turn the selector (detail 3 - fig. 1) to RESET for 5 seconds and then to (winter) or (summer) and “CU” will be

displayed.

Operate the DHW knob (detail 2 - fig. 1) to adjust the required curve from 1 to 10 according to the characteristic (fig. 14).

By setting the curve to 0 sliding temperature adjustment is deactivated.

fig. 12 - Compensation curve

Turn the selector (detail 3 - fig. 1) to RESET for 1 second and then to (winter) or (summer) to exit compensation

curve setting and “CU” will be displayed again.

Turn the heating knob (detail 1 - fig. 1) clockwise and “OF” will be displayed.

Operate the DHW knob (detail 2 - fig. 1) to adjust the curve shift (fig. 15).

fig. 13 - Parallel curve shift

Turn the selector (detail 3 - fig. 1) to RESET for 5 seconds and then to (winter) or (summer) to exit parallel curve

adjustment mode.

If the room temperature is lower than the required value, it is advisable to set a higher order curve and vice versa. Pro-

ceed by increasing or decreasing in steps of one and check the result in the room.

fig. 15 - Example of parallel compensation curve shift

AIf the Remote Timer Control (optional) is connected to the boiler, the above adjustments are managed accord-

ing to that given in table 1.

Table. 1

Heating temperature adjustment Adjustment can only be carried out from the Remote Timer Control menu.

DHW temperature adjustment Adjustment can only be carried out from the Remote Timer Control menu.

Summer/Winter changeover Summer mode has priority over a possible heating demand from the Remote

Timer Control.

Eco/Comfort selection On disabling DHW from the Remote Timer Control menu, the boiler selects

Economy mode. In this condition, selection from the boiler panel is not possi-

ble.

On enabling DHW from the Remote Timer Control menu, the boiler selects

Comfort mode. In this condition, selection from the boiler panel is possible.

Sliding Temperature Both the Remote Timer Control and the boiler card manage Sliding Tempera-

ture adjustment: the boiler card Sliding Temperature has priority.
