1. Press and release the WARMER icon. The top of the F in °F of
the top drawer will begin to flash. This will allow you to adjust the
temperature of the top drawer. In 10 seconds of inactivity, the
bottom bar of the F in °F will begin to flash (see below); this will
allow you to adjust the temperature of the bottom drawer.
Adjustments to the lower drawer can be made immediately if the
LIGHT icon is pressed.
2. While the top or bottom bar of the F in
°F
is flashing, press the
WARMER or COOLER icon as required to adjust the set-point
temperature. The change will be set five seconds after adjusting the
temperature and the new set-point temperature will be displayed.

This default temperature is used by the controller to maintain the
temperature zones in your unit.
The default temperatures are a recommendation. If further
temperature adjustments are required, use the following procedure
to adjust the set-points.
1. Press and release the desired zone WARMER icon to put the
controller in the SET TEMPERATURE mode. The current range
symbol will show on the display (top, Figure 24).

VIEWING ACTUAL TEMPERATURE
- ALL MODELS EXCEPT 2275DWRWS/2275ZWC/
2275ZWCOL
There are two modes to view temperature. In viewing temperature
in these modes, any offsets are taken into account. This means that if
you place a thermistor in a known temperature, let’s say ice water, it
may not read the 32°F that you would assume. If the control offset
was preset at -3°F while you placed the thermistor in an icebath, the
actual thermistor reading when viewing actual temperature would
read 35°F. In the unit this would cause the cabinet to push itself 3°
cooler. To view pure thermistor readings, you must go into the
service menu and choose the correct option.
To view T1 (normally refrigerator temperature) hold the WARMER
key for approximately five seconds until the “F” flashes. Release and
the display will show the corrected refrigerator temperature. For
Wine Cooler models the display will cycle through all three zones.
These temperatures are approximate and calibrated for a cabinet in
normal ambient temperatures with some product load. Checking a
completely unloaded cabinet may result in other temperatures. Not
available on CLR2160.
To view T2-T4, hold both the WARMER and COLDER keys for
approximately five seconds until the first thermistor reading appears.
At this time the display will cycle through thermistors 2-4 and their
accompanying readings. If a thermistor is not used on that particular
model, it will show “0” and if the thermistor is not working, it will
show an ER.
