BOILER IGNITION (fig. 1)

Ensure the gas supply is turned on lower

the control panel cover and activate the boi-

ler by rotating the selector knob to the sum-

mer positio ( ).

The lighting-up of the green led ( ) will

indicate that the apparatus is switched-on

and ready.

–

ith 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.

– ith 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”.

sted by turning the knob of the D.H. .

potentiometer ( ). hen 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

( ). hen there is no request for hea-

ting or D.H. . production (the leds

and are off), the tank unit maintenan-

ce temperature will appear on the red

led scale 35÷80°C.

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-
