"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;

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.

Formal definition of adaptive control system is in section 1.20

An essential element of adaptive systems would be removal consumer

judgment from some or all of the wash cycle selection process.

Test load size table was created for use in testing adaptive systems.

Test load size is linked to measured clothes washer capacity.

Manual Control systems require testing with max. and min. loads.

Adaptive control systems require max ., min., and average size loads, as a

minimum and in some cases may require (2) additional test loads.

Procedures as defined are applicable to all. clothes washers (i.e., HA, VA,

compact, or standard)

New Load Usage Factors are defined for products with adaptive systems. The

LUF's for manual controlled products are unchanged .

Adaptive systems do not include any concept requiring soap, soil level

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.

Note; Water heating clothes washers which also consume hot supply water;

It is recognized that this test Procedure does not account for reheating of the initial portion of hot supply water that is less than the defined

test procedure hot supply water value, due to household supply line losses and seasonal and geographic variations. An appropriate factor

must be developed and applied to the first term in equations in section 4.1.2. 1, or a field test conducted comparing water heating clothes

washers which also consume hot supply water to water heating clothes washers which do not consume hot supply water.
