## "Adaptive control systems" refers to a clothes washer control system which is capable of

automatically adjusting `,washer operation or washing conditions, without the need for consumer intervention, and/or actions, based 'on characteristics of the test load placed in the clothes container.. Examples would be clothes washer control system independent selection, modifications, or absolute control of water fill level, wash water temperature, agitation and/or tumble cycle time, number of rinse cycles, spin speed, etc. Note: The energy consumption of any adaptive system which relies on the use of, detection of, or the presence of either soil, soap, suds, or any additive laundering substitute or complimentary product to alter the "normal" operation of the clothes washer must be determined following the field test procedures defined in section 6.1; \' ,,:.

# G. FIELD TESTING Spngo Was/i S step ner Consumption Test 

## For washer controls or systems that cannot be adequately measured for energy consumption by the test procedure, or cannot be calculated using a procedure generally accepted by DOE and other manufacturers, a field test must be conducted. The field test shall consist of a minimum of 10 test units and 10 base units, with a minimum of 50 cycles per unit. The units shall be monitored in such a way as to accurately record the total energy consumption per cycle. At a minimum, the following 

## must be measured and recorded throughout the test period for each test unit: Hot water usage in gallons, electrical. energy in kilowatt-hours, and the cycles of usage.

### 33% Warm Rinse Usage Considering all clothes washers, 20% of all loads are rinsed in warm water. However, approximately only 60% of the total number of clothes washers have a warm rinse option available.Therefore, the 20% warm rinse usage needs to be applied to only 60% of the machines. This will more accurately reflect how these machines are used by the consumer.

Since 20% is 1/3 of 60%, warm rinse is selected for 33% of the loads on machines which have warm rinse available.
