OMAHA, Neb. — Bes-Tech Inc. has announced a demand response option for its Digi-RTU™ HVAC rooftop unit optimization technology. The new feature accepts the demand response load limit factor signal from any third party’s demand response controller.

The Digi-RTU is an aftermarket control package designed to optimize rooftop units, matching space load with the rooftop unit’s output. The company said the Digi-RTU supports load limiting from 0 to 100 percent by modulating the speed of the rooftop unit’s compressor(s) and supply fan.

The Digi-RTU has been installed on rooftop units on a variety of buildings including offices, manufacturing facilities, distribution centers, retail, and government.

According to the company, benefits of the control include:

• Reduces electricity demand and consumption up to 60 percent.

• Communicates with building automation systems and stand-alone thermostat.

• Demand response enabled.
