BOILER
IGNITION
(fig. 1)
Open the gas valve, 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.
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”.
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 tap, and if
the temperatures foreseen are low, empty
the boiler and the hydraulic system to avoid
breakage in the tubes due to the freezing of
the water.
C.H. TEMPERATURE
ADJUSTMENT
(fig. 2)
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.
