Adjusting Set-Point (Temperature Adjustment)

To adjust set-points, touch the appropriate WARMER or COLDER key on control panel in multiple key strokes until
the desired set-point is achieved (See Figure 2-7). Each key stroke equals a one degree change and is accompa-
nied by an audible beep. When the desired set-point is reached and the keys are no longer being touched, the set-
point will flash ON and OFF at two (2) second intervals for ten (10) seconds, then the current zone temperature will
be displayed.
NOTES:
• During initial pull-down the real-time compartment temperatures will be displayed, then once set-point tempera-
tures are achieved, the temperature shown in the LCD can change by no more than one (1) degree per minute.
• The temperature range in a freezer zone is -5°F (-20°C) to +5°F (-15°C).
• The temperature range in a refrigerator zone is +34°F (+1°C) to +45°F (+7°C).
• Initial factory set-points are 0°F (-18°C) in a freezer zone and 38°F (3°C) in a refrigerator zone.
• The initial stroke of the WARMER or COLDER key will change the previous set-point by one degree.

Ice Maker System ON/OFF

All units are shipped with the ice maker system switched OFF. By touching the ICE MAKER key on the control
panel, power is allowed to the ice maker system and the single ice cube icon appears in the LCD (See Figure 2-8).
To switch the ice maker system OFF, touch the ICE MAKER key again and the single ice cube icon disappears.
NOTES:
• Power to the freezer lights is monitored to help control icemaker operation. If the freezer door is open, power to
the ice maker system is interrupted, unless the icemaker is filling with water at that time. After the door is closed,
power is not allowed to the ice maker system for an additional three (3) minutes, unless the Maximum Ice
Production feature has been initiated.
• The ice maker system will continue to produce ice if the ice bucket is not in the correct position. However, to help
prevent the ice maker system from filling the freezer with ice, the electronic control will not allow twenty (20) con-
secutive ice harvests between any two door openings.
• To allow ice to freeze fully and reduce effects of low water pressure, power to the ice maker system is interrupted
for forty-five (45) minutes after each ice harvest. This can be bypassed for service purposes by switching the ice-
maker system OFF, then back ON with the ICE MAKER key.
• The fill tube heater is energized 100% of the time whenever the ice maker system is ON.
• When in Sabbath Mode, the icemaker system is disabled. Sabbath Mode will be explained later.
