FIN for Equipment Controllers

Ideal for the development of controller products for HVAC, refrigeration, renewable energy, and other markets

FIN can be run on embedded microprocessor controller platforms that support Linux, providing comprehensive and easy to configure control logic, with a web-server for configuration and user interface graphics. FIN's wizard creation app allows developers to rapidly create very easy-to-use, de-skilled configuration processes for use on mobile devices. 

Equipment controllers powered by FIN 

FIN Framework has been designed for OEM manufacturers, making it easy to create specific control strategies and associated graphics and configuration wizards. FIN can help you bring your new product to market faster with lower development costs. FIN runs embedded on single or dual-core processors that support Linux and a JVM. We can also offer a new version of FIN* for smaller platforms, which does not require a JVM, so has a significantly smaller footprint. FIN provides a comprehensive suite of functions avoiding the need for you to develop complex firmware in-house. 

Choose to buy and build any combination of FIN features with your hardware, software tools, and apps. You get the latest technology with tagging and data modeling built-in, with support for the latest Haystack standard. FIN supports multiple open protocols and all visualization is HTML5 compliant for an excellent mobile client experience.
