COMFORT OF HOT WATER USE
• Possibility of connection to an external indirect cylinder, with solar integration, for single installation with special diverter valve kit and installation in array.
• Comfort setting of domestic hot water directly from the boiler (single installation)
HEATING COMFORT
• Performance up to 108% and energy saving up to 35%.
• **** stars for combustion performance according to EN 92/42.
• Full premix analog burner with stainless exchanger.
• Reduced pollutant emissions, class NOx5 (NO<30 mg/kWh) corresponding to a reduction of 40% for CO2 and 75% for NOx compared to old generation boilers
• S.R.A. proportional climate control of temperature in two heating zones, activated directly from the control panel, capable of optimizing performance levels according to ambient and room temperatures (single installation).
• Possibility to connect to a heating system thanks to EBUS2 (hydraulic devices, temperature control accessories).
• Operation and programming control via LCD screen, with text menu to scroll through: operating temperatures, self-diagnosis, daily and weekly programming, setup information and log of most recent errors (single installation).
• Electronic control unit for installation in an array, which allows: climate configuration and room temperature regulation, temperature and power control, ignition priority control to ensure balance of use of the generators, control of the hot water production circuit with an external cylinder, etc.
EASE OF USE AND INSTALLATION
• Extremely small dimensions and weight for a generator that offers so much power.
• Integrated minimum pressure switch.
• Easier Start: Automatic ventilation function and combustion analysis with direct access.
• Simplified maintenance: front access to all components.
• High performance, fully proportional pump (accessory) so that we have the minimum possible consumptions and guaranteed high yields.
• Full range of installation, plumbing, control and exhaust accessories available. They are all already dimensioned and easy to apply.
• Integration with Expert Control: new and intuitive climate control to manage 3 circuits based on space and/or outside temperature for greater comfort and energy savings.
• Designed for wired analog thermostats - bus interface board included.
ENERGY SAVING AND RESPECT FOR THE ENVIRONMENT
• Up to 23% energy savings with Expert Control and SRA mode
• Up to 35% energy savings with analog regulation, external sensor and underfloor heating (array installation)
• Reduced emissions
