Adjusting The Temperature; Temperature Mode; Temperature Sensor Error Codes - Marvel ML24BN Series Installation, Operation And Maintenance Instructions

USING YOUR ELECTRONIC CONTROL - INDOOR MODELS

Adjusting the temperature:

To set or check the set-point temperature (with the control
out of sleep mode), press the "-" or "+" keypads. "SET" will
be indicated on the user interface panel and the current
set-point temperature will display and flash. Subsequent
presses of the "-" or "+" keypads will adjust the temperature
colder or warmer respectively. When you have reached
your desired set-point temperature, press the "On/Off" key-
pad to accept, or do nothing and the "Set" mode will time-
out in 10-seconds accepting the displayed temperature as
the new set-point.
The available set-point temperature range for your appli-
ance is 34°F (1.2°C) to 60°F (15.6°C). If you attempt to
adjust the temperature outside of this range you will receive
an audible notification.
CAUTION
!
If you are using the appliance as a refrigerator for perish-
able foods, the set-point temperature should be set be-
tween 34°F and 42° F (1.2° C and 5.7° C).
When initially loading your product with warm contents, it
may take up to 48-hours for the storage compartment tem-
perature to stabilize.
When making temperature set-point changes, it may take
up to 24-hours for the stored contents to stabilize at your
new set-point temperature.
