NURO®
Touch-Screen Control System
Developed in-house and equipped with the latest in boiler control technology, theNURO® Touch-Screen Control System is designed with efficiency in mind. The NURO®monitors and modulates the combustion and ignition of the boiler to maintain the desired outlet temperature, minimizing the efficiency gap between the boiler and the system. Should issues arise, system diagnostics pinpoints and troubleshoots errors, producing operation solutions and common repair suggestions.
