Cycles
Auto Hot Start:
Auto Hot Start is initiated by the control board when it senses water temperature is below 80°F. If the water
is below 80°F after prewash, the unit circulates for 1 to 5 minutes (depending on the cycle selected) and then
drains for 75 seconds. This procedure repeats up to 4 times or until the water reaches 80°F.
Added Heat:
The added heat option differs for the various cycles. Some cycles will not be modifi ed, some cycles will
increase the calrod time, and some cycles will get additional segments added (e.g., AUTO has 6 segments
without added heat and 9 segments with added heat).
Heated Dry:
During HEATED DRY, the heater cycles at a rate of 60 seconds on and 51 seconds off.
Cycle Explanations and Exceptions:
• Turbidity Response is used during the SANITIZED, NORMAL, and AUTO cycles only.
• Timed cycles can change depending on the water temperature. If the minimum temperature is not met,
an extended time is added until the temperature is met or the time expires.
• Partial Drain and Fill Algorithm is used during NORMAL and AUTO cycles only.
• Auto Hot Start may cause the fi rst prewash to repeat up to 4 times.
• Disabling
STEAM will shorten the cycle time.
• If
STEAM is selected during NORMAL or AUTO cycles, turbidity response is ignored, and cycle defaults to
the heavy soil algorithm.
• HEATED
DRY takes 34 minutes for the NORMAL cycle while the other cycles vary to as long as 60
minutes for PLASTICS. There is no HEATED DRY for the RINSE cycle.
• Drain Overlap is a short period when both the wash and drain pumps run simultaneously as the
circulation cycle ends and draining begins.
• Drain Pause is a short period between the circulation cycle ending and the drain starting.
• Extend Times enables both the circulation pump and heater to operate simultaneously.
Turbidity Response
The turbidity response is measured in DC volts. Four to 5 VDC registers light soil and a shorter wash cycle,
while 0 to 2 VDC registers heavy soil and a longer wash cycle. SANITIZED wash measures the turbidity
response during the third prewash cycle and adjusts the time based on these measurements. NORMAL wash
measures the turbidity response during the fi rst prewash and the prewash before the main wash. If a clean
response is measured during the fi rst prewash, the cycle advances directly to the main wash with no drain or
fi ll. If a clean response is measured during the prewash before the main wash, the control shortens the active
heater time.
