Series R1K/B ideal for connection with external boiler / solar. The wall-mounted boiler comes with a pre-installed temperature sensor with an 8m cable so that the boiler of our choice can be integrated into the boiler's digital control. The temperature selection in the boiler is done through the DIGITECH® SYSTEM. The boiler maintains this temperature steady within the boiler, achieving savings. Once a week, the boiler raises the temperature in the boiler to 70°C for disinfection (Anti-Legionella function).

The ONE-TECH® condensation exchanger ensures higher thermal efficiency, lower thermal load losses, and ease of maintenance work. The DIGITECH® SYSTEM displays the temperatures and functions of the boiler with large letters and icons, allowing the desired temperature to be set degree by degree with great precision.

Control capability: external sensors, solar panels, sensors for external boiler, autonomy valves, and a multitude of other additional accessories. The boiler components are arranged to be easily accessible. This arrangement allows for the easy replacement of the transformer as well as the repair of other components.

• Non-return valve: "Clapet" for easy connection to central exhaust systems.
• Total flue gas barrier: Traps the temperature in the exchanger area.
• Inverter circulator with PWM: Increases or decreases the speed/flow of water in the circuit.
