    The ERC generation of parametric controllers are designed to increase energy efficiency and reduce production costs.

    The ERC refrigeration controller offers:

    • steady operation in harsh environments (triple moisture protection)
    • voltage protection algorithms for trouble free compressor operation in all climate conditions
    • special algorithms for optimization under poor power supply conditions.

    A. O. Smith introduces the Voltex hybrid electric water heater.

    The Voltex operates in one of three modes. In “efficiency” mode, the water heater relies almost entirely on the heat pump. In “hybrid” mode, it switches back and forth between the heat pump and standard electric heating elements depending on the hot water demand. In “electric” mode, the Voltex operates like a standard electric water heater and is Energy Star® rated.
