The ECO3™ is an easily installed controller specifically developed as a state-of-the-art, secondary controller for air conditioning and refrigeration systems. It optimizes the energy efficiency of air conditioning and refrigeration systems with one or two compressors. The controller is available in two different models: the ECO3 Single and the ECO3 Dual. The Single is compatible with single compressor air conditioning and refrigeration systems, while the Dual is compatible with any air conditioning system with two compressors. Both models wire directly into the control circuit between the existing control and the compressor. Energy savings are easily monitored on the display, and the ECO3 can be manually bypassed if desired. The controller has the ability to save energy on the cooling and heating cycles of compressor-driven heat pumps.
