Auxiliary Equipment Operation
TEMPERATURE SETTINGS
Soft Touch Refrigerator-Freezer Control Panel
Your sub-zero refrigerator is equipped with a manually
controlled touch pad thermostat with digital read-outs.
There are separate soft key buttons for the refrigerator to
starboard and freezer to port.
Each time a touch control button is pressed for either
compartment the unit will adjust for a colder or warmer
desired temperature.
The actual freezer temperature will show on the port side
of the display panel and the refrigerator temperature will
show on the starboard side of the display.
Note that there is a "ice" touch button which controls the
ice making cycling .
The alarm button when energized will sound if the re-
frigerator or freezer compartment doors are left open for
extended periods.
For further information refer to the sub zero refrigerator
operator's manual in the owner's information packet.
