STone: the programming ecosystem for smarter HVAC/R development

 

Build faster.
Validate earlier.
Deliver better software.

HVAC/R manufacturers are facing a new level of complexity: shorter development cycles, increasingly connected units, higher software quality expectations and growing cybersecurity requirements. 

STone is CAREL’s advanced programming ecosystem designed to help technical teams develop, test and maintain HVAC/R control software with greater speed, consistency and confidence. Enhanced by STone copilot, it brings generative AI directly into the programming environment, supporting developers in code generation, optimisation and troubleshooting while helping teams improve software quality and accelerate innovation.

 

Why STone matters 

Faster development

A modular architecture simplifies coding and helps teams reuse logic across different CAREL programmable controllers, reducing repetitive work and accelerating project delivery. 

Better teamwork

STone supports more structured software development, making collaboration between developers, validation teams and technical departments more efficient. 

Higher software quality

Advanced testing, debugging and simulation tools help identify issues earlier, reduce project risks and support continuous software validation. 

Full lifecycle support

From design and development to commissioning, maintenance and future updates, STone supports the entire lifecycle of the HVAC/R unit. 

 

 

AI, security and scalability for the next generation of HVAC/R software

AI-assisted programming

Developers can describe what they need and receive support to generate code, optimise logic, analyse anomalies and improve software consistency.

This allows engineering teams to focus on what really matters: innovation, performance and differentiation.

Designed for connected, secure equipment

In a connected industrial world, cybersecurity is no longer optional. STone supports secure software development and helps protect applications from unauthorised access and tampering.

For HVAC/R manufacturers, electronics teams and system integrators

STone helps organisations improve software development processes, reduce time-to-market and create scalable software assets for future equipment platforms.
