| (1) Low temperature means for condensing boilers 30 °C, for low temperature boilers 37 °C and for other heaters 50 °C return temperature (at heater inlet). (2) High temperature regime means 60 °C return temperature at heater inlet and 80 °C feed temperature at heater outlet. (*) At the maximum flue distance, the flue length should be reduced by 1 meter for every 90° bend and 0.5 meter for every 45° bend. |

The Gas Adaptive Technology automatically detects gas quality and prevents improper combustion, ensuring safety. Proper combustion maximizes energy efficiency, utilizing the full potential of the gas.
The use of wide-channel, seamless, single-coil stainless steel domestic hot water heat exchangers ensures a long lifespan.
With a wide modulation range of 1:7, it can reduce its power, allowing you to adjust its capacity according to your needs and save both gas and electricity.
By selecting the pre-heating parameter in your combi, the waiting time for hot water usage is minimized.
With a hot water capacity of up to 15 liters per minute, it allows you to simultaneously use hot water from two taps.
Featuring brass and composite components that are resistant to thermal stresses and corrosion, ensuring a long lifespan and years of trouble-free use.
Illuminated, large information screen that allows for control of heating, hot water, pressure, and adjustments.
Operates very quietly thanks to high level of insulation.
Achieving the best class level, which is level 6, for NOx as stipulated by the ErP Directive, helps reduce air pollution by lowering harmful NOx emissions.
High Protection System/bypass circuit and prevents the pump from overworking
