30,000 BTU Multi Zone Inverter Heat Pump -4°F Low Ambient Heating Outdoor Unit with 32,000 BTU Heating Capacity, Inverter (Variable Speed Compressor), Low Ambient Operation, Auto Operation, Self-Diagnosis, Defrost/Deicing and Gold Fin Anti-corrosion. Instead of shutting off once the desired temperature is reached, an Inverter compressor continues to operate at low speed to maintain that temperature. The air conditioner is quieter to operate and uses less energy than conventional ACs, which cycle on an. Shuts down the indoor fan to prevent cold air from being blown into the zone. Removes frost from the outdoor coil when the outdoor temperature is low. A self-troubleshooting function that makes it easier to diagnose malfunctions, reducing service labor. Provides three levels of comfort from which to choose. Temperature and fan speed will set automatically. Automatically restarts the air conditioner to programmed setting when the electricity comes on after a power failure. All DFS system outdoor air conditioner coils have a corrosion resistant GoldFin coating standard from the factory. GoldFin will promote sustainable efficiency and coil life by helping to prevent corrosion caused by everyday pollutants. The low ambient operation to 14°F (Cooling Mode).
