CBLI? (Service Use) {F005}

Report the configuration of cool/bypass/liquid injection valves in a given
system configuration.
CCT= / CCT? {F006}

Set or query the Cool Cycle Time: the on/off period assigned to the
proportioning cooling valves, in seconds.
CH= / CH? (Not Yet Implemented) {F007}

Define steering of loop-dependent commands to ch.1 or ch.2 in a dual-loop
system.
CLOCK= / CLOCK? (Not Yet Implemented) {F008}

Define or query the existence of Real Time Clock hardware.
CLRALARM

Clear alarm conditions from the system, if any exist. Restore ALMCODE? to
0. If the condition creating the alarm state persists, however, the system will
restore the alarm until that condition is corrected.
CPB= / CPB? {F010}

Set or query the width, in degrees, of the band about setpoint (SP) over which
the control system will proportion the cooling valves (Cool Proportioning
Band).
CTLREM= / CTLREM? {F011}

Set or query the use of the remote sensor for temperature control of the
system. Value 0 (off) means "control from the internal sensor"; 1 (on) means
"control from the remote sensor". If the remote sensor is not connected (open
circuit), the system will automatically revert to internal-sensor control and an
alarm will result.
CURRSNS? (Service Use) {F012}

Query the existence of pump/compressor current sensors as defined by the
system hardware complement (factory set). 0 = off/don't exist; 1 = on.
DATE= / DATE? (Not Yet Implemented) {F013}

Set or query date in Real Time Clock option.
DB= / DB? {F014}

Set or query the deadband, in degrees, between the heat and cool
proportioning bands (HPB/CPB). This value is usually negative, implying
overlap.
DEFAULT (Not Yet Implemented)

Restore factory default values to the programmable parameter table.
DEGREES= / DEGREES? {F016}

Set or query the temperature scale used on the display and in further RS-232
communications. 0 = Celsius, 1 = Fahrenheit, 2 = Kelvin.
