Introducing The Digi-RTU®

The Digi-RTU® is an innovative add-on control to improve the energy efficiency of DX rooftop units (RTUs).

By intercepting heating and cooling calls, this unique control varies the speed of the fan and compressor to match loads while maintaining space conditions.

The Digi-RTU® technology is approved for energy efficiency incentives in Connecticut by both Eversource and the United Illuminating Company; in Massachusetts by Eversource, National Grid, Cape Light Compact; and in Rhode Island by National Grid.

In 2011, the American Public Power Association selected the Digi-RTU® for their DEEDS Energy Innovator Award.
