ELECTRIC WALL BOILER
Series ELEKTRA. … BP-L HE
Presentation
Thank you for choosing an electric wall boiler FIAMMA, built with the most modern
technologies, safe and tough materials, so as to ensure maximum efficiency of use, total
quality of the device and extreme safety for the user.
The series Elektra .. is built according to European standards dir. machines 2006/42 - IEC
60335-2-21:2012 IEC 60335-1:2010 and EN 60335-2-21:2003 + A1 : 2005 + A2 : 2008 -
EN 60335-1:2012 - EN 62233:2008 .
The obtained results can be summarized in the following key points:
- Noiseless functioning, thanks to maximum insulation of the device by means of
innovative special materials that ensures minimum heat loss.
- High degree of reliability, thanks to a careful choice of materials and to sever tests
carried out during production for each unit built.
- High performance with maximum efficiency, thanks to a modulation of electrical power to
the heating elements, according to the actual need of energy by the system or the need of
sanitary water. The system D.E.S. manages the device with temperature probes
positioned in each sensitive point of the boiler, so as to manage both comfort and
economy functioning, in order to reduce power consumption when the device is not used
at the maximum capacity or demand.
- The appliance is fully adjustable both in water temperature of the heating system (with
the possibility to choice of system at high and low temperature for underfloor systems) and
in the domestic hot water temperature.
- The assembly of the components has been realized in order to allow an easy access to
them, all from the front of the unit, for ordinary and extraordinary maintenance.
We recommend you to follow our instructions, and we suggest to contact the area
authorized service FIAMMA in order to prepare a planned maintenance contract which can
ensure suitable operation at maximum efficiency and safety, so that your machine use can
go a long way.
In renewing our thanks, our technical department and our sales network, are at your
disposal for any further information

CONTROL PANEL
The control panel is composed of : display, function selection keys, general
switch and the hydrometer it is placed in the lower left corner
in front of the unit (see image above).
Using analogical hydrometer.
The analogical hydrometer control panel has a dial with unit of measure in a
bar, from 0 to 6 bar. The water pressure in the heating system is indicated by
the index of the black arrow.
The optimum pressure for the system is between 1 and 1.5 bar.
More than 1.5 bar you can have a maximum pressure of 2 bar (maximum
expansion of the system during the rise in temperature). More than 2 bar
pressure the system is not in the range of operation, and mechanical safety
valve (preset to 3 bar) can start to lose water.
The minimum operating pressure is 0.8 bar (+/- 0.2 bar). The differential
positive or negative tolerance is due to the operation of the water pressure
switch with fixed setting.

CONTROL OF MAIN HEAT EXCHANGER
According to the required power during the heat request, the controls G1-G4 related to the
main exchanger are turned on all or partially.
The actuation of each control is reduced to a lapse of 4 seconds. Higher is the required
power, more the control will remain operative in this lapse.
The power in heating or during a sanitary request is calculated by PID algorithm.
Please see in the pictures below two examples related to 40% and 60% of total power.
In case of simultaneous request of heating and tank, the controls G1-G4 related to the
main heat exchanger will be directed in the following way:
Boilerstatus PrimaryG1-G4 TankG5
Only heating request G1 – G4 =
modulation G5 = OFF
Heatingrequest +TankrequestG1–G3=modulation
G4=OFF G5=ON
Heatingrequest +FlowswitchrequestG1–G3=modulation
G4 = OFF G5 = ON
Controls rotation:
Every hour the order of ignition of triac G1-G4 controls is rotated in such a way to partition
evenly in time the use of all heating elements.

CONTROL OF EXERNAL PROBE
Installation and functioning at sliding temperature
For the connection of the external probe, it shall be used the
Original Kit FIAMMA code F.532 provided in the accessories of the
electric boilers Elektra.
The electrical connection shall be done in the external terminal at
the general electric panel already prearranged in the standard
cabling of the boiler. The connection must be carried out with
junction cables and wires having a minimum section of 1,5 mm and,
if possible, avoiding the insertion along with electric lines, digital
lines of inverter or other not compatible.
After the connection the external probe must be enabled by means of the introduction of a
variation ofN°1 parameter, changedfrom0to1.
Then the setpoint chased by the heating delivery probe will be calculated as follows:
Ti = [ (Troom – T e) * K e / 10 ] + Troom
Example of calculation for several values of Ke
The coefficientKeistheleakage ofthe building and itcanbe setbyN°2 parameter.
Te, is the temperature measured by the external probe.
Troom is the setpoint related to the desired room temperature.

DEGASSING FUNCTION
The degassing function is activated by simultaneously pressing the keys J4 and J7.
During this function are altered states of operation to maximum and minimum speed of the
circulating pump PWM in order to facilitate the escape of air bubbles from the hydraulic circuit.
The sequence is illustrated below.
When this function is on the display shows a timer indicating the time at the end of the function.

N°6 .If the value of temperature measured by the primary heat exchanger probe is lower than the
programmed delivery setpoint, the triac are ignited in sequence as for required power. This occurs only
after a settable time by parameter N°5 . The instant power of the boiler and the related control of triac G1-G4
