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

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.
Continuous
(no period after temperature)
Energy Saving
(period after temperature)

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.
