1.2 Preliminary checks
a
WARNING
– Should it be necessary to access the areas in the
bottom part of the appliance, make sure that the
system components and pipes are not hot (risk of
burning).
– Before replenishing the heating system, put on
protective gloves.
The initial start-up of
Edea T
must be carried out by profes-
sionally qualified personnel, after which the appliance can
function automatically. It may be necessary for the user to re-
start the appliance automatically, without contacting the tech-
nician; for example, after a holiday.
First of all, check that the gas isolation and water system
valves are open.
1.3 Ignition
After completing the preliminary checks, start up
Edea T
:
– set the main system switch to "ON" in order for the display
to show the pressure level in the system during refilling
–
check that the operating mode on the display is "Stand-by"
and
if necessary select it by pressing the button
s
once or twice
ON
Fig. 2
– check that the pressure in the heating system, when cold, is
1-1.2 bar
. If the pressure is less than this, use the external
filling device to repressurise the system to
1-1.2 bar
– ensure that the filling device is turned off after use
– press and hold the button
y
for more than 3 seconds and
check whether normal operating conditions are restored.

– select the "SUMMER"
l
operating mode by pressing and
holding the
y
button for at least 1 second. The delivery
temperature detected at that moment will appear on the
display
– open one or more hot water taps.
Edea T
will work at its
maximum power until the tap or taps are closed.
Once
Edea T
is commissioned in “SUMMER mode”
l
, with
the
y
button, pressed for at least 1 second, it is possible to
choose the “WINTER mode”
n
. The display will show the val-
ue of the delivery water temperature measured at that time.
In this case it is necessary to adjust the room thermostat(s) at
the desired temperature or, if the system is equipped with a
timer-controlled thermostat, verify that it is “active” and ad-
justed.
1.4 Adjusting the delivery temperature
To increase or decrease the delivery temperature of
Edea T
,
instead of modifying the specific parameter, it is possible to
turn knob
t
on the control panel. The temperature can be set
to between 20 and 80°C.
