Challenge

Seltron wanted to empower HVAC professionals with a modern toolset for managing, configuring, and maintaining their clients’ heating systems — remotely and efficiently. Traditional workflows required on-site visits, manual configuration, and frequent back-and-forth with homeowners, often leading to miscommunication, inefficiencies, and added costs.

To solve this, Seltron needed a dedicated application built specifically for maintainers — one that would work seamlessly with the SeltronHome platform and provide deep insight into system behavior and configuration.

Solution

NOMNIO designed and developed SeltronHome °Kelvin, a web and mobile app tailored for heating system maintainers. Built as part of the broader SeltronHome ecosystem, °Kelvin delivers professional-grade tools for smarter, faster, and more confident support:

• Remote Diagnostics & Full System Access
  Maintainers can view and adjust every parameter of their clients’ heating systems — without needing to visit the site or ask the user to read settings over the phone.
• Real-Time Monitoring
  SeltronHome °Kelvin allows live monitoring of critical system metrics, enabling technicians to see exactly how a heating system behaves over time and identify potential issues proactively.
• Season Simulation & Testing
  Maintainers can simulate different environmental conditions — such as winter settings during summer — to test and optimize system behavior during setup, maintenance, or annual checkups.
• Configuration Assistance & Guidance
  The app includes built-in tips and best practices, helping less experienced technicians configure systems effectively and confidently, even when dealing with complex setups.
• On-the-go- & Field-Ready
  Whether in the office or on-site, maintainers have all the tools they need in a streamlined, mobile-friendly interface.

Outcome

SeltronHome °Kelvin has become an essential tool for Seltron’s professional partners, delivering:

• Fewer on-site service visits thanks to powerful remote capabilities
• Faster, clearer diagnostics and system setup
• Improved service quality and consistency across technician skill levels which means higher client satisfaction
• A scalable, modern support experience that strengthens the SeltronHome platform and Seltron’s brand
