The use of the INOX heat exchanger, the copper pipes, the brass fittings for mechanical tightening as well as the individual high-quality components give a homogeneous whole that contributes to the smooth operation of the boiler and its durability over time.
Its compact dimensions allow installation in places with limited available space. Its simple yet modern design helps it to integrate perfectly into any space.
The combination of the front and perimeter thermal insulation, the sound-absorbing funnel and the newly designed air/gas mixer ensure the boiler extremely low noise levels (<52dB at 100% of its operation) both during ignition and during of its operation.
The DIGITECH® SYSTEM displays the temperatures and boiler functions in the most easy-to-use and easy-to-read way, with large letters and icons. Ability to set the desired temperature per degree with great precision for economy. It has the ability to control: external sensors, solar panels, sensors for external boiler, autonomy valves and many additional components.
The DIGITECH® electronic board has an easy-to-read display. All information is given in large letters and icons so that the information is given quickly and easily. The design of the buttons combined with the color choice of the cover give a perfect final aesthetic result and make handling it an easy task.
DIGITECH® offers continuous control of operating parameters and quick identification of potential malfunctions through special fault indication codes. With the built-in memory function, you inform the technician about the latest malfunctions of the boiler, so everyone always has a picture of its operation.
The DIGITECH® electronic board allows us to connect the boiler with a multitude of digital accessories in order to adjust its operation, based on the needs of the installation. Accessories include temperature sensors, wireless or wired room thermostats, with OT+, with Wi-Fi, etc.
The components of the wall-mounted boiler are arranged in such a way that they are all easily accessible, for checking them and for any repairs that may arise, e.g.
-the closed expansion tank is on the side with the valve in front, for easy maintenance.
-the hydraulic connection of the closed expansion tank is at the top so that it can be easily replaced.
-the transformer is not part of the management board, as a result of which its replacement is done easily, quickly and at a very low cost in contrast to the replacement of the board that has the transformer built in, which is a time-consuming and costly process.
- all parts are connected with brass fittings, resulting in easy repair.
- the special sound-absorbing funnel helps reduce noise.
-all components are made of branded high-quality materials, eg Callefi.
