KONm presents all the "Quality Stars" to satisfy every need: Exceptional modulation ratio up to 1:8 Efficiency >107% (ex dir. CE 92/42) Primary exchanger in ultra-flat Al/Si/Mg Electronics with HWS “Hot Water Speed” function (vers. C) Low NOx (class 5 according to EN 297 and EN 483) thanks to the modulating premix burner Production of hot water up to 13.3 l/min Δt 25 with special 12-plate (mod. 24 C) and 16-plate (mod. 28/35 C) stainless steel exchanger “Pit stop” maintenance Simple and intuitive control panel Prepared for future applications in systems and suitable for meeting the requirements of the new installation standards High efficiency modulating circulator Managing 2 zones with 2 KON m thermostats is versatile. Ideal for all systems, thanks to the electronics that allow you to manage 2 heating zones at different temperatures (high for radiators and fan-coils, low for radiant panel systems) by controlling them with dedicated modulating and on-off thermostats Anti-overheating post-circulation of 15 seconds, it maintains the thermal equilibrium between delivery and return, even after intense DHW withdrawals, while in heating, with a duration of 5 minutes, it allows all residual thermal inertia to be disposed of. Sliding temperature operation for maximum running economy Antifreeze protection intervenes at 5°C and is activated in both DHW and heating, bringing the temperature in the boiler to 15°C. The risk of KON m freezing if low temperatures persist in the room where it is installed is avoided. If there is a lack of gas, the lockout signal will appear on the display. Pump anti-blocking prevents blocking of the pump following long stops thanks to an automatic 5-second impulse that the electronics sends to the motor every 24 hours of stop. Chimney sweep function adjustment of combustion easier than ever. Pressing the release button for more than 5 seconds to obtain operation at minimum or maximum power for 15 minutes, for an accurate analysis of the combustion The details of konm... Strengthened by the company's constructive synergies, KONm summarizes some aspects of the high-end series such as the primary heat exchanger in Al/Si/Mg with low water content by "Scuola Unical", the original rapid inspection mechanism of the vital parts of the combustion together with the extensively tested but updated complex of electronics and electro-pneumatic control pre-mixing system already in use on other ranges. A sober answer with high technological content "ErP Ready", ideal for the consumer who approaches technologies with high energy recovery and for the installer who requires simple but not trivial solutions in plant replacement or in new buildings with low environmental impact . KONm is signed by Unical. Exclusive exchanger in Al/Si/Mg It is made of a special Aluminium/Silicon/Magnesium alloy which ensures efficiency and resistance, so much so that it is guaranteed by Unical for 5 years. Thanks to the internal heat exchange configuration, efficiencies of over 107% are achieved in condensing mode, which means great economic savings and very low environmental impact for the user. The 28-35 versions are adequately oversized Modulating circulator with deaerator It represents the state of the art in the high efficiency standard. In line with the 2015 ErP directive, with less than 1 W consumption in stand-by and only 45 W in maximum operation, thanks to the wide modulation capacity, based on the request of the room thermostat and the temperatures detected by the sensors placed in delivery/return, it automatically doses the power of the boiler to the needs of the system. Particularly silent and compact, it integrates with the safety valve, the by-pass and the drain cock. Fan and electro-pneumatic gas valve The pre-mixing unit made up of a pneumatic gas solenoid valve and modulating fan stands out for its limited overall dimensions. Advantages: compactness and silence wide 1:8 modulation range absolute operating safety due to the absence of turbulence low thermal and mechanical stresses, therefore long life, thanks to the inalterability. The valve is designed to compensate for gas pressure fl uctuations present in networks as well as to stabilize the supply pressure independently of the suction pressure generated by the premix fan. The 28/35 version is equipped with a silenced air intake to improve acoustic performance and also with a larger air intake manifold. Easily adjustable, it ensures an accurate air/gas combustion mixture to ensure high CO2 levels and favor condensation with very low CO and NOx levels. In summary, the monoblock lends itself to easy maintenance and accessibility. Exchanger cleaning 1 minute and 46 seconds! KONm is the result of the experience of the Service and market suggestions, from which the Unical design staff has synthesized a technological complex that can be easily assembled and quickly disassembled. Intuitive controls The on-board electronic panel will feel immediately familiar. Last but not least: all wiring and intervention operations are facilitated by the vertical tilting system. The multifunction LCD display, with timed backlighting, allows: Reading of the temperatures in heating and DHW Display of blockage due to lack of fl ame Operating/stand-by status Diagnostics with signaling of 11 anomalies Knob: stand-by, mode selector and heating adjustment 30 - 85°C DHW adjustment knob 38 - 60°C Product Guarantee All products for sale on our site are new and packed.
