BARGAIN AREA Ferroli condensing boiler Bluehelix HiTech RRT 34C 0T4B7AWA complete with fume exhaust kit

Boiler control

The new user interface with ''capsense'' technology, without mechanical keys and equipped with a 2.8'' graphic display, allows the user to interact with the product in an easy and extremely simple way, customizing the operation of the appliance in way to manage environmental comfort according to your needs. Thanks to the remote connection via bus this can also be done directly from the CONNECT remote control, even via smartphone. The boiler is also designed to connect a second room thermostat on dedicated terminals to manage multi-zone systems.

TOP EFFICIENCY Even on old systems (replacements)

The exchanger of the THERMOBALANCE™ thermal unit of BLUEHELIX HITECH RRT (fig. A) compared with the more classic and widespread steel exchanger (fig. B) also used in the past by the Ferroli Group exclusively on a small series of boilers produced for the market English, and then immediately abandoned in favor of the evolution towards the proprietary steel exchanger used in the Bluehelix models (2012 -> ). This geometry allows the exchanger of the THERMOBALANCE thermal unit to operate almost at maximum design efficiency even in conditions of partial clogging, while for the same quantity of deposits and sediments (e.g. due to installation on old systems) the exchanger in fig . B tends to clog much more quickly in the part in contact with the flame due to the reduced fluid passage area, in which a real barrier of deposits * is formed which hinders heat exchange and reduces efficiency beyond below nominal values

MC2

Multi Combustion Control The electronics control the flame ionization current in order to guarantee optimal combustion as the air density or gas quality varies. The relationship between the air/gas ratio (λ) and the flame ionization signal is used to control the air-gas ratio itself and therefore combustion. MC2: Multi Combustion Control, the new combustion system with patented gas-adaptive technology improves the adaptability of use as the conditions of the gas network change (e.g. fluctuations or reduced pressures).

EASY MAINTENANCE Problem-free maintenance

At the time of the first maintenance, the technician can realize the care with which every detail has been designed to facilitate his work. Thanks to the maximum accessibility of the main components, the “Thermobalance”TM thermal unit allows maintenance to be carried out with maximum precision and speed. Some examples:

• Internal accessibility is favored by the 3-piece casing with removable sides.
• The electrical box of the electronic board can be easily extracted from the chassis, leaving free access to the internal parts. - The fan, offset from the burner and placed underneath, must not be dismantled to access the steel burner-exchanger group.
• The burner door is totally self-cooled by air and therefore does not require an insulating panel, avoiding the risk of this being damaged or broken during disassembly for cleaning.
• The burner can be dismantled by loosening just 3 bolts, leaving free access to the stainless steel exchanger.
• The exchanger with extra-large passages is designed to challenge the hardest waters and is easily cleanable thanks to the non-collectorised single tube circuit.
• The domestic water inlet filter can be extracted extremely easily directly from inside without having to remove the boiler's hydraulic connections.
• Any disassembly and replacement of the plate exchanger occurs simply by removing two Allen bolts accessible from the front
