TRIPST2? (Service use) {F068}
Query trip temperature, in degrees, of cascade condenser, for turn-on of the
second stage refrigeration.
UPHOURS? {F069}
Query total hours of system operation (including off), from engagement of
Emergency Off switch.
USPANH= / USPANH? {F079}
Set or query SP upper operating limit, in degrees, as determined by the user's
requirement. This limit may not exceed the value FSPANH? or SSPANH?
USPANL= / USPANL? {F080}
Set or query SP lower operating limit, in degrees, as determined by the user's
requirement. This limit may not be more negative than the value FSPANL? or
SSPANL?
WAKE= / WAKE? (Not Yet Implemented) {F070}
Set or query the status of the automatic-wakeup function.
WAKEMINS= / WAKEMINS? (Not Yet Implemented) {F071}
Set or query the elapsed time to automatic wakeup.
WAKETIME= / WAKETIME? (Not Yet Implemented) {F072}
Set or query the automatic-wakeup time set via Real-Time Clock option.
WINDOW= / WINDOW? {F073}
Set or query the window, in degrees, used to determine process stability
(conformance to setpoint), as reported by the system "Alarm/Ready" contacts.
WINTIME= / WINTIME? {F074}
Set or query the time constant, in seconds, used to determine process
stability (conformance to setpoint), as reported by the system "Alarm/Ready"
contacts. This time is a time constant used in the stability integration and
determination algorithm, not an absolute time value. Small movements in
process temperature will be determined to be stable more rapidly than large
swings. This value is used to prevent over/undershoot of the setpoint
temperature from yielding a premature "ready" result.
ZEROCAL (Not Yet Implemented)
Command to restore all calibration constants to the unbiased state (zero
offset, unity gain).
