CODE	TITLE	DESCRIPTION
#
		Inapplicable Functions Display ----------
		Condenser pressure is displayed using a pressure transducer. Pressure is
	Condenser Pressure	displayed in units of psig when code 28 is set to _F and units of bars when
Cd13		function code Cd28 is set to _C. “P” is displayed after the value to indicate psig,
	(CPC)	“b” appears after the value to indicate bars and “i” appears after the value for
		inches of mercury.
		Compressor discharge pressure is displayed using a pressure transducer.
	Compressor	Pressure is displayed in units of psig when function code Cd28 is set to _F and
Cd14	Discharge Pressure	units of bars when Cd28 is set to _C. “P” is displayed after the value to indicate
	(Optional)	psig, “b” appears after the value to indicate bars and “i” appears after the value
		for inches of mercury.
Cd15	Unloader Valve	The status of the unloader valve (if present) is displayed (on or off).
	(On--Off)
Cd16	Compressor Motor	Records total hours of compressor run time. Total hours are recorded in
	Hour Meter	increments of 10 hours (i.e., 3000 hours displayed as 300).
Cd17	Relative Humidity	This code is only applicable to units with a humidity sensor (HS). This code
	(%) (Optional)	displays, as a percent value, the relative humidity at that time.
Cd18	Software Revision #	The software revision number is displayed.
		This code checks the Controller/DataCORDER battery pack. While the test is
		running, “btest” will flash on the right display, followed by the result. “PASS” will
Cd19	Battery Check	be displayed for battery voltages greater than 7.0 volts and for alkaline batteries
		with voltages greater than 7.5 volts, “FAIL” will be displayed for battery voltages
		between 4.5 and 7.0 volts, and “------” will be displayed for battery voltages less
		than 4.5 volts. After the result is displayed for four seconds, “btest” will again be
		displayed, and the user may continue to scroll through the various codes.
Cd20	Config/Model #	This code indicates the dash number of the model for which the Controller is
		configured (i.e., if the unit is a 69NT40-511-105, the display will show 11105).
Cd21	Future Expansion	This code is for future expansion, and is not in use at this time.
Cd22	Compressor Speed	The status of the compressor is displayed (high, low or off).
	(High--Low--Off)
	Evaporator Fan
			3
Cd23	Speed	Displays the current evaporator fan state (high, low or off).
			SECTION
	(High--Low--Off)
	Controlled	This code shows the state of Controlled Atmosphere (enabled or disabled), if
Cd24	Atmosphere State
		equipped.
	(On--Off) (Optional)
	Compressor Run	This code displays the time remaining until the unit goes into defrost (in tenths of
Cd25	Time Remaining	an hour). This value is based on the actual accumulated compressor running
	Until Defrost	time.
	Defrost Termination	The defrost termination sensor (DTS) is located immediately above the
Cd26		evaporator coil. It is used by the Controller for defrost initiation and termination.
	Sensor Temperature	(See Figure 2-2.)
