The new BV series variable-speed air handler is designed with a multispeed blower and reduces temperature swings while using less electricity, according to the manufacturer. The product is available in electric/no heat and water-heat models. Each unit has an LED control board displaying the system's operating status. The BV series units also have a soft-start feature that turns the blower motor on at a slow speed and ramps up to the appropriate airflow.
