Introducing The Digi-RTUTM

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