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 selec- ted temperature. The gas feeding pressure will then auto- matically vary to ensure that the requi- red temperature is kept constant. – With the rotary switch in the winter position ( ) once the boiler has rea- ched the value set on the heating poten- tiometer, it will start to modulate in auto- matically in order to supply the required power output to the system. The opera- tion 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 tempera- ture 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 hea- ting or D.H.W. production (the leds and are off), the tank unit maintenan- ce 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. potentio- meter ( ). The set temperature is indi- cated 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, con- densation of the combustion by-products is obtained, further increasing the effi- cency 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 elec- tricity supply, close the gas cock, and if the temperatures foreseen are low, empty the boiler and the hydraulic LIGHTING AND OPERATION SPIA VERDE Fig. 1 GREEN LED SPIA GIALLA SPIA ROSSA Fig. 2 RED LED YELLOW LED USER INSTRUCTIONS VERY IMPORTANT!

To attempt a boiler restart, rotate the selector knob to position ( ) and relea- se it immediately, placing it in the sum- mer ( ) or winter ( )operation posi- tion. If the boiler lock-out re-occurs, contact an authorised Service Centre. – Insufficient water pressure (fig. 4) If the red "0.5" bar led starts flashing, the boiler will not function. To restore functioning fill the system until the green “1 bar” led lights up. If all the leds are off, call the local autho- rised technical staff. 2 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 elec- tric cable. Should this require replace- ment, contact exclusively with the autho- rized technical staff.
