Description
Retrofit efficiency optimizer controllers for single-zone rooftop-unit (RTU) air conditioners harness multiple energy saving techniques by replacing simplistic stock control units with digital controls, new sensors, and upgrading single speed supply fan motor to variable frequency drive motor controllers. These retrofits can reduce supply airflow to better match partial building loads, more carefully control outside air ventilation to the minimum amount necessary to maintain indoor air quality, and implement advanced economizer controls eliminating the need to operate the compressor when advantageous ambient conditions prevail.
