The ATC system uses a thermistor located in the water supply tubing between the water inlet valves and the and the vacuum break (See Figure 1). The thermistor senses the incoming water temperature and provides input to the ATC control board. The ATC control board uses the input from the thermistor to cycle the hot and cold water solenoids on the water inlet valves to achieve the desired water temperature. A triac located on the control board, cycles the hot and cold water solenoids through the water temperature switch (See Figure 2). Figure 2 WHIRLPOOL CONSUMER SERVICES Model 6ALBR6245JQ0 Page 4 of 23 The ATC system will provide 24°C ± 3°C For the COLD setting and 38°C ± 5°C For the WARM setting. With the temperature selector switch set to COLD, the cold water solenoid energised for 100% of the time and the hot water solenoid is cycled on and off (See Figure 3). With the temperature selector switch set to WARM, the hot water solenoid energised for 100% of the time and the cold water solenoid is cycled on and off (See Figure 4). Note : During the warm water fill, both solenoids are energised for 55 seconds. After 55 seconds, the hot water inlet valve stays on and the cold water inlet valve cycles. The ATC is only active during the wash fill, it has no effect on the rinse water temperature. WHIRLPOOL CONSUMER SERVICES SERVICING THE ATC COMPONENTS Model 6ALBR6245JQ0 Page 5 of 23 1.
