DP= / DP? {F017}
Set or query the use of integer/decimal format on the control panel display. 0
(decimal point off) displays temperature rounded to the nearest integer; 1
(decimal point on) displays temperature with 0.1 resolution.
DT= / DT? {F018}
Set or query, in seconds, the [derivative] time constant applied to the
proportioning band adjustment, as a function of rate of change in the process
temperature.
FLUID= / FLUID? {F019}
Set or query the number defining the fluid type in use in the system (see
system programming documentation for a listing). Fluid definition
automatically sets FSPANH and FSPANL, subject to SSPANH and SSPANL,
to limit the permissible bounds of the setpoint (SP) and the alarm
temperatures ALARMH and ALARML.
FORMAT= / FORMAT? (Not implemented / obsolete) {F020}
Describes the format of transmitted data. Task offloaded to the host
processor.
FSPANH? {F021}
Query the high temperature limit (degrees) established by the FLUID
definition.
FSPANL? {F022}
Query the low temperature limit (degrees) established by the FLUID definition.
GNREM= / GNREM? {F023}
Adjust or query the calibration gain factor applied to the remote [external]
temperature sensor.
GNRTD= / GNRTD? {F024}
Adjust or query the calibration gain factor applied to the system [internal]
temperature sensor.
HEATER? (Service Use) {F025}
Query the system heater configuration and phase connection definition.
HLPC? (Service Use) {F026}
Query the existence of high-low-pressure cutout on the system
compressor(s). Used in water-cooled units. 0 = not used, 1 = exists.
HPB= / HPB? {F027}
Set or query the width, in degrees, of the band about setpoint (SP) over which
the system will proportion the power applied to the heater (Heat Proportioning
Band).
HYSTLI? (Service Use) {F028}
Query the hysteresis, in degrees, applied to activation of the liquid injection
valve.
