Abstract: A method for operating an air conditioner unit includes a step of initiating a resistance heating cycle of the air conditioner unit. The method further includes a step of determining a plug personality of a plug of the air conditioner unit. The method also includes a step of determining a nominal voltage rating of the air conditioner unit. The method further includes a step of determining, based on the plug personality and the nominal voltage rating, a pulse width modulation rate percentage for a single bank resistance heater of the air conditioner unit. The method may also include a step of setting, within a memory of a heater controller, the determined pulse width modulation rate percentage for the single bank resistance heater.

Abstract: An air conditioner unit comprises a sealed cooling system including an outdoor heat exchanger and an indoor heat exchanger. The sealed cooling system includes multiple refrigerant circuits. Each refrigerant circuit of the multiple refrigerant circuits includes an expansion device. A cross-over flow connection extends between and provides fluid communication between each of the multiple refrigerant circuits. The cross-over flow connection is adjacent the expansion device of each refrigerant circuit.
