DESCRIPTION
Following the Minimum Off Time, should a compartment tem-
perature drift this far above or below setpoint in the Perishable
Range or above setpoint in the Frozen Range, the unit will re-
start.
This selects the override temperature for the Minimum Off
Time portion of the Auto Start-Stop Off Cycle. During the Min-
imum Off Time, should the refrigerated compartment tem-
perature drift this far above or below setpoint in the Perishable
Range, or above setpoint in the Frozen Range, the unit will
override the Minimum Off Time, and restart.
OFF - There is no maximum off time.
When a minute value is selected, this is the longest amount
of time the unit will remain off during a (Perishable or Frozen
or both) Auto Start/Stop Off Cycle. When this time expires, the
unit will restart and run for the Minimum Run Time, regardless
of any temperature change inside the compartment.
This only applies to Frozen Setpoints in Start-Stop operation.
This offset is the number of degrees below setpoint that the
unit will run before cycling off. This will allow for a lower aver-
age compartment temperature when considering temperature
rises during off cycles.
If the switches are all configured "Switch Not Installed", this
parameter will not display.
NO = the system will respond to the switch as configured.
YES = the configured action on activation of the switch will be
overridden and the action will be alarm only. The purpose of
this setting to temporarily override the Configuration setting in
situations where shutdown or speed change is not desired.
Temperatures will display in either Fahrenheit (°F) or Celsius
(°C). (for North American Units, this function may be locked)
Pressure will display in either psig or (bar).
(for North American Units, this function may be locked)
Date will display in either US (MM/DD/YYYY) or European
(DD/MM/YYYY) format.
YES = In the Driver Mode, the alarm code and alarm descrip-
tion will be displayed.
NO = In the Driver Mode, only the alarm code will be dis-
played.
Higher numbers increase the contrast of the display screen.
