6.3 - OPERATION
Domestic hot water production
Make sure that the selector (B) is
positioned on ( )
Position the domestic hot water
temperature knob (C) on the de -
sired temperature.
- completely to the left = 38°C
- completely to the right = 60°C
By adjusting the temperature of the domestic hot
water at a temperature very close to that actually
used, you will avoid mixing hot water with cold
water, with management savings and significantly
reducing the formation of limescale.
By opening a hot water tap, the
appliance is automatically activat -
ed and delivers water at the set
temperature.
During the sampling stage, the dis -
play shows the temperature of the
domestic hot water and the symbol
(
) stays lit up.
Antifreeze protection only
The boiler is equipped with an antifreeze protection
system.
To activate the antifreeze function only, position
the two knobs as shown in the figure.
The antifreeze protection inter -
venes only if the boiler is powered
electrically and if the gas valve is
open.
If for some reason there is a power
or gas failure, the antifreeze protec -
tion described above is not active.
Heating
mode
For operation in heating mode the
knob (B) must be positioned in the
field shown in the figure,
- In correspondence of MIN
the temperature is minimum =
30°C
.
- completely to the right = 85°C
If the heating system is equipped
with a modulating room thermostat
(TA mod), put the knob (B) in cen -
tral position.
During the heating stage, the dis -
play shows the water temperature
and the symbol ( ) stays lit up.
Complete decommissioning
To decommission the system,
disconnect the boiler from the
power supply by acting on the main
switch.
In the event of complete decom
-
missioning, the heating and hot
water production modes as well
as the antifreeze protection are
completely disabled.
If idle for long periods, close the
gas shut-off valve and cold water
cock, if present
.
