ATC (Auto Temperature Control)

ATC is the control function that the washer controls water temperature with temperature sensor (thermistor).

Because there are numerous water temperatures depending on the customer’s environments (cold

areas, warm areas, various water temperatures, settings of heater temperature, etc.), ATC function in

our washer maintains the certain level of wash temperature to output the best washing performance at

each cycle.

If you select normal cycle, this cycle is the regulation and UL cycle. Since new washers must reduce

the amount of energy usage as a first priority, customers will notice more cold water entering the

washer. But, this is normal, not a problem.

In this regulation cycle, Hot temperature is similar to acceptable adult bath-water temperature and

warm temperature is similar to comfortable swimming-pool water temperature.

If customers want to wash clothes in specific water temperatures, customers should choose a different

cycle at each temperature (Hot/Warm).
