BOILER IGNITION (fig. 1)

Ensure the gas supply is turned on lower the control panel cover and activate the boiler by rotating the selector knob to the summer positio ( ). The lighting-up of the green led ( ) will

indicate that the apparatus is switched-on and ready. –

With the rotary switch in the summer position ( ) the boiler will start-up upon demand for domestic hot water, and run at full power to reach the selected temperature.

The gas feeding pressure will then automatically vary to ensure that the required temperature is kept constant.

– With the rotary switch in the winter

position ( ) once the boiler has reached the value set on the heating potentiometer, it will start to modulate in automatically in order to supply the required power output to the system. The operation of the boiler will be stopped through the intervention of the thermostat or “Logica Remote Control”.

TEMPERATURE ADJUSTMENT (fig. 2)

– The D.H.W. temperature can be adju-

sted by turning the knob of the D.H.W. potentiometer ( ). When there is a demand for hot water, the set temperature is displayed on the red led scale from 35÷80°C and the yellow domestic hot water led lights-up at the same time ( ). When there is no request for heating or D.H.W. production (the leds and are off), the tank unit maintenance temperature will appear on the red led scale 35÷80°C.

–

The C.H. temperature can be adjusted by turning the knob of the C.H. potentiometer

( ).

The set temperature is indicated on the red led scale from 35÷80°C and the yellow heating led lights up at the same time

(). If the temperature of the C.H. return water is lower than around 55° C, condensation of the combustion by-products is obtained, further increasing the efficency of thew thermal exchange.

TURNING THE BOILER OFF (fig. 1)

To turn the boiler off place the selector knob on the OFF position. If the boiler is not going to be used for a lengthy period it is advised to turn off the electricity supply, close the gas cock, and if the temperatures foreseen are low, empty the boiler and the hydraulic

system to avoid avoid frost damage.

GAS CONVERSION

Should it be necessary to convert the appliance to a different gas from the one

for which the boiler has been equipped, approach the technical staff.

CLEANING AND MAINTENANCE

Preventive maintenance and checking of

the efficient operation of the equipment and safety devices must be carried out exclusively by the authorized technical staff. The boiler is supplied with an electric cable. Should this require replacement, contact exclusively with the authorized technical staff.

IN SAFETY CONDITION

SPIA ROSSA

When the boiler is connected to the “Logica Remote Control” regulator, the selector CR/OFF/SUM/WIN/UNBLOCK must be placed in the position ( ); the knobs of the hot-water service heating potentiometers do not have any ef fect and all of the functions will be managed by the regulator (fig.

7). If the “Logica Remote Control” breaks

down, the boiler will function by placing the selector on the ( o ), position, obviously without consequent control of the room temperature.

The operating instructions are reported inside the cover (fig. 8). Each setting or modification is displayed (fig. 9).

–

Safety stat trip

(fig. 5) If the safety thermostat trips, the red "35°C" led will start flashing. In order to attempt a boiler restart, rotate the selector knob to position ( ) and release immediately, returning it to the summer ( ) or winter ( ) position.

If the boiler lock-out occurs again, call local authorised Service Centre for technical assistance.

Other anomalies

(fig. 6)

When one of the red

“40÷80°C”

leds start flashing, switch-off the boiler and then try to ignite again. After 2 or 3 unsuccessful attempts, do not try again but call authorised technical staff.

If it is too hot or too cold in your apartment, you can easily adjust the fixed temperature with the temperature knob.

Before adjusting it again, however, allow the temperature to stabilise first.

Note: With the temperature knob you can only adjust the fixed temperature, whilst the redu-

ced temperature remains the same.

– Adjusting the temperature

If you turn the knob towards the + sign, the fixed temperature is increased by about 1 °C for every notch.

If you turn the knob towards the - sign, the fixed temperature is decreased by about 1 °C for every notch.

Before adjusting the temperature of the regulator, the thermostatic valves, which may be present, have to be regulated to the desired temperature.

For every operation of the Info key the following list of items, one af ter the other, are displayed. The thermo-feeler continues to function independently of the display.

ACTIVATING

During functioning the lid of the regulator must be closed.

If the rooms remain unused for a long period of time, the temperature can be reduced with the on-line key, in this way saving energy. When the rooms are occupied again, press the on-line key to re-heat them. The current choice is displayed on the display:

– On-line key

Fixed temperature heating

Reduced temperature heating

NOTA:

In automatic mode, the apparatus switches from the fixed temperature to the reduced temperature according to the temporal programme. The manual switching of the temperature is done manually with the on-line key.

– Temperature regulation

Fixed temperature: temperature when the rooms are occupied (basic setting)

Reduced temperature: temperature during periods of absence or night

Hot-water service temperature: – desired temperature of hot-water service – comfort temperature of the hot-water service

(with storage capacity boiler unit)

Reduced temperature of hot-water service (with storage capacity boiler unit): temperature desired for hot-water service at reduced level. To have access to the “reduced hot-water service temperature” parameter, press the and keys at the same time for at least 5 seconds and then go along the entered lines with the key until parameter 61 is reached. Regulate the value with and

Before proceeding with the adjustment in the temperature on the regulator, the thermostatic valves, which may be present, have to be regulated to the desired temperature.

PROGRAMMING

For the programming the lid of the regulator must be open.

As soon as the cover is open, the display and the key functions are switched on. The number in the square represents the programme lines that may selected with the arrow keys.

With the Logic Remote Control it is possible to manage the temperature of boiler unit on two levels (a comfort level and one at reduced temperature) in accordance with the programme chosen with parameter 62 (load hot-water service). To have access to the parameter press the and keys for at least 5 seconds and then go along the entered lines with the key until parameter 62 is reached. At this point four different programmes may be selected with o keys, with the following characteristics:

0 = 24 hours/ day - Hot water always available at the temperature set in parameter 3.

1 = standard - Hot water according to the daily heating programme. In the comfort periods

of the heating the temperature of the boiler unit is regulated at the value set via parameter 61.

2 = sservice suspended.

3 = second daily programme (8) - Everyday of the week the temperature of the hot-water ser-

vice is set according to programme B. In this case the programming is one for all the days of the week and three periods of time are available. In the periods of time set, the temperature of the boiler unit is controlled via the temperature setting of parameter 61.

Start phase 1: preparation of the boiler unit to the comfort temperature

End phase 1: Temperature of boiler unit maintained at the reduced value

Start phase 2: Preparation of boiler unit to the comfort temperature

End phase 2: Temperature of boiler unit maintained at the reduced value

Start phase 3: preparation of boiler unit to the comfort temperature

End phase 3: Temperature of boiler unit maintained at the reduced value

With the heating programme it is possible to set the switching times of the temperature for a period of a week. The weekly programme consists of 7 daily programmes. One daily programme allows 3 phases of heating. Each phase is defined by a starting time and a finishing time. The n. 8 daily programme is for the hot-water service. If a phase is not required, the same starting and finishing time may be entered.
