• Modern and intuitive touchscreen HMI, with representative icons and capacitive keys with acoustic "buzzer" sound
• Modern and linear design with under-boiler connection cover available as an accessory for excellent aesthetic integration
• Specific DHW electronic functions: DHW delay, anti-short cycle function and smart fan
• Hydraulic unit with DIN standard sequence
• Low consumption circulator (IEE?0.20) 7 m with high head available as an accessory
• Ease of installation, integration even in confined spaces and replacement thanks to the wide choice of accessories available as optionals
• Modulation ratio 1:8
• Easy maintenance and cleaning of the combustion chamber thanks to the front access to the exchanger – Seasonal efficiency 93%
• 8-litre side expansion tank
• Standard flue gas flange with dedicated flue system
• Standard thermoregulation in combination with the external probe, available as an accessory
• Possibility of recessed installation (model 25 KIS and 30 KIS) and outdoors in partially protected places (IPX5D)
• Assembly crosspiece already integrated in the boiler and power supply cable supplied
• Natural gas operation as standard with the possibility of conversion to LPG (G31) and propane air using accessories. This modification is the responsibility of the installer or the technical assistance service.
• IPX5D electrical protection degree.
