The data keys provide the user with many displays of
individual system temperatures, pressures, and other op-
erating data. These keys have multiple displays, which
can be seen by repeatedly pressing the SYSTEM DATA
or the ▲ or ▼ (

key and its messages is provided below.
SYSTEM 1 DATA Key operation
The SYSTEM 1 DATA key provides the user with access
to system 1 operating parameters. The following is a list
of the data in the order in which it appears.
The first key press of the SYSTEM X DATA key displays
all of the measured system pressures (oil, suction, and
discharge).
The second key press of the SYSTEM DATA Key or the
▼ (DOWN ARROW) key displays all of the measured
system temperatures (oil, suction, and discharge).
SYS 1 PRESSURES OIL = XXXX PSIG
SUCTION = XXXX DISCHARGE = XXXX PSIG
The next key press displays the suction temperature
and all of the calculated suction temperatures (saturated
suction and system superheat).
SYS 1 TEMPERATURES OIL = XXX.X °F
SUCTION = XXX.X DISCHARGE = XXX.X °F
The next key press displays the discharge temperature
and all of the calculated discharge temperatures (satu-
rated discharge and discharge superheat).
SYS 1 SUCTION TEMP = XXX.X °F
SUPERHEAT = XXX.X SAT TEMP = XXX.X °F
SYS 1 DISCHARGE TEMP = XXX.X °F
SUPERHEAT = XXX.X SAT TEMP = XXX.X °F
The next key press displays the system 1 motor thermis-
tor temperatures.
SYS 1 MOTOR TEMPS T1 = XXX.X °F
T2 = XXX.X °F T3 = XXX.X °F
