Series ELEKTRA Compact.. BP-L
Presentation
Thank you for choosing a FIAMMA electric wall boiler, a product that features the latest
heating technologies, and robust and safe materials that ensure maximum efficiency
during use, the highest appliance quality and utmost safety for the user.
The Elektra Compact... series is built according to European Machine Directive 2006/42 -
IEC 60335-1:2010 and EN 60335-2-21:2003 +A1:2005 + A2:2008 - EN 60335-1:2012 - EN
62233:2008.
The result is a product with several distinguishing features:
- Particularly quiet operation, with maximum insulation of the unit by means of innovative
special materials, for minimum heat loss.
- High level of reliability due to the careful choice of materials and the rigorous tests carried
out on each appliance after production.
- High yield, with maximum efficiency thanks to the modulation of the electric power to the
heaters following the actual energy requirements of the system, or the sanitary water
production needs. The D.E.S. system manages the appliance by means of temperature
detection probes positioned in every sensitive point of the boiler, allowing the regulation of
the "comfort" or "economy" operating modes to your requirements, in order to reduce
consumption when the appliance is not used at maximum power or demand.
- The appliance is fully adjustable both as far as central heating system water temperature
(with the possibility of choosing high and low temperature system for underfloor heating)
and sanitary hot water temperature.
- The components have been coupled together so that they are all easily accessible from
the front of the unit during routine and extraordinary maintenance activities.
We suggest that our recommendations are carefully followed, and that you contact an
authorised FIAMMA service centre in your area to agree a scheduled maintenance
contract, which will ensure that your appliance always operates at maximum efficiency and
safety, and that it lasts a long time. In thanking you again for your choice, we would like to
remind you that our technical offices and our technical-commercial network are always at
your disposal to provide you with any information of a technical or general nature that you
might require.

Heating system water pressure reading
The analogue hydrometer on the control panel has a bar dial from 0 to 6 bar. The current
central heating system water pressure is indicated by the black needle. The optimum
central heating system water pressure is between 1 and 1.5 bar. The pressure can exceed
1.5 bar, to a maximum of 2 bar (maximum expansion of the system during a temperature
rise). Pressures over 2 bar are not within the operating range of the appliance. When this
level is exceeded, the action of the pressure transducer will cause the display of the
" ERROR F 10 " error message and the boiler will remain in operation. However, if the
threshold of 2.8 bar is exceeded, the system stops until the pressure falls back within the
allowed range. The minimum operating pressure is 0.8 bar (+/-0.2 bar). If the pressure
detected by the transducer is less than 0.7 bar, the " ERROR F 1 " message appears
and the operation of the system stops. The last safety feature of the boiler is the
mechanical valve, which when a pressure of 3 bar is reached starts to release water
through the VSR drain, the position of which can be found in the hydraulic connection
diagram (see page 6).
SWITCHING ON THE BOILER
The boiler is switched on by pressing the luminous main switch found on the left of the
display in the dashboard. If the boiler is connected to a single-phase power supply source,
the button lights up when pressed (230-240 V - 50 Hz). After the short graphic
presentation, set the day and time (if required) and choose summer/winter operating mode
using the ■ (SW5) key at the bottom right (pressing again will switch off the boiler, while
keeping it powered).
