RANGE RATED CERTIFICATION
The maximum power, in heating mode, of Edea T boilers can
be adapted, during the installation, to the thermal needs of
the system by modifying the setting of PAR 15 in the
0 .. 100
range.
The setting of PAR 15 = 100 is the factory setting that allows
the boiler to deliver its maximum power in heating mode. It
can be reduced by modifying the setting of PAR 15 as shown
in the table appearing below.
Once the new setting of PAR 15 has been made, the reduced
maximum power value (kW)
for models with power above 35
kW
MUST MANDATORILY be applied beside the boiler’s data
plate. For checks and adjustments after the modification,
refer to the new value for the maximum power.
The useful nominal power levels used are those relative to the
operating conditions (80-60°C) (Pn min - Pn max).
Example for Edea 25 T boiler:
– default heating power range: 2,3 - 24,5 setting of PAR 15 = 100
– “reduced” heating power range: 2,3 - 20,1 setting PAR 15 = 80

5 DESCRIPTION OF THE APPLIANCE
5.1 Characteristics
Edea T are last generation condensing wall mounted boilers
which
Sime has produced for heating and instant domestic
hot water production when combined with a storage tank. The
main design choices made by
Sime for the Edea T boilers are:
– the total pre-mix microflame burner combined with a stain-
less steel heat exchanger with a plaster outer shell, for
heating
– room sealed, Type C appliance. Suitable for use on sealed
heating systems
– the electronic control and command circuit board with mi-
croprocessor, for optimal management of the heating sys-
tem and modulation of up to 1:10 for the instant produc-
tion of domestic hot water. It allows for connecting room
thermostats, an auxiliary sensor for managing kits, and the
external sensor. The presence of the external sensor will
make the boiler work at a variable temperature, in other
words, the temperature in the boiler will vary in relation to
the outdoor temperature, in accordance with the optimal cli-
matic curve selected during the installation phase, result-
ing in considerable energy and financial savings. Moreover,
the command board has an internal connection for inserting
an expansion board which is used to control external relays.
Other special features of the
Edea T boilers are:
– the anti-freeze function which activates automatically if the
temperature of the water inside the boiler falls below the
threshold of the value set at parameter "PAR 10" and , if
there is an external sensor, if the external temperature falls
below the threshold of the value set at parameter "PAR 11"
– anti jamming function of the pump and diverter valve, this
activates automatically every 24 hours if no request for heat
has been made
– the chimney sweep function lasts 15 minutes and makes
the job of the qualified technician easier when measuring
the parameters and combustion efficiency
– screen display of the operating and self-diagnostic param-
