h)Compressor Run Time (F7)

To display the compressor run time between the two most recent defrosts, follow the steps below.

1)Make sure the jumper is removed between the connector K151 pins 7 and 8 on the control board. Otherwise you will not be able to access this feature.

2)Press and hold both the button and the unmarked, blank button for 5 seconds. "F0" should appear in the display window. Press the MANUAL DEFROST button until "F7" appears in the display window.

3)Press the unmarked, blank button to display the run time. The number displayed indicates what percent of the time the compressor was running.

4)Press the MANUAL DEFROST button to return to the menu screen. Press and hold

both the button and the unmarked, blank button for 5 seconds to exit the setting mode and return to the temperature display.

5)If a jumper was present between connector K151 pins 7 and 8, reconnect it after all setting and diagnostic work is complete.

4.Operating Modes

Hoshizaki undercounters and worktops feature two operating modes, energy saving and continuous. Always use the default setting of your unit. To determine the default setting of your unit, see the chart below.

Model	Default Setting
Refrigerator (auxiliary code Q5 and earlier)	Continuous Operating Mode
Refrigerator (auxiliary code Q6 and later)	Energy Saving Operating Mode
Freezer - 1 section	Continuous Operating Mode
Freezer - 2 section	Energy Saving Operating Mode

To determine the operating mode your unit is in, look at the unit's cabinet temperature display. If a period does not appear after the temperature, the unit is in continuous operating mode. If a period appears after the temperature, the unit is in energy saving operating mode.

To switch between operating modes, press and hold the unmarked, blank button for 5 seconds.

Note: It takes 5 seconds for this setting to be saved. Once saved, the setting you made will be remembered even if the power is turned off.
