Energy Zone (EZ) software operates with Microsoft Windows and is very fast and easy to use. No previous programming experience is needed to configure or operate any aspect of the system.

The heart of the EZ system is the Remote System Controller (RSC). The RSC is a 16 bit microcontroller, with full stand-alone capability.

The PC host computer can control up to 256 RSCs and each RSC can control up to 4 HVAC zones for a total of 1024. Larger configurations are possible by networking.
