U-Line 2275DWRWOL, 2275DWRWS Forced Defrost, ICE Thickness Adjust, Temporary SHUTDOWN/OFFICE Mode

FORCED DEFROST

This will allow the unit to defrost quickly. For R and WC units, this is just an off cycle. For units with hot gas defrost the unit will enter a hot gas defrost per the specification. Hold the LIGHT key and press ON/OFF three times. The unit will beep once when entering this mode. To exit this mode either do the same key combination or turn the unit off via the display. Not available on CLR2160.

ICE THICKNESS ADJUST

This will allow addition or subtraction of up to five minutes from the ice-making cycle. To enter this mode hold the up arrow and press the down arrow three times. The unit will beep once and display the current ice thickness. To adjust up or down use the arrows. Press LIGHT key when completed. Please refer to the ice thickness section of the manual to view proper cube sizes and recommendations.

Only available on CLR2160 and CLRCO2175.

TEMPORARY SHUTDOWN/OFFICE MODE

In some cases it may be requested for the unit to be shut down for short periods during meetings for example. To do this hold the down arrow and press the up arrow three times.

RELAY STATUS

To see which relays are operating, hold the down arrow and hit ON/ OFF three times. The unit will scroll through all relays and whether they are on or off. See specific unit section for explanation.

MODEL NUMBER CHANGE

Only the main circuit board requires model number selection. The display board is universal and will automatically adapt to the unit it is plugged into. The model number can be changed with the board installed or uninstalled from the unit. To program uninstalled you will need a display board and a power supply. For the power supply hook a neutral wire up to pin 10 and a 120V wire to pin 8 of the circuit board.

9.Restore factory defaults

This will restore the default set-point, defrost and offset values.

10.Adjust thermistor 1 offset—10 to +10F
