FLOATING This configuration variable specifies the output type to drive the
connected actuator for the output 1:
FLOATING/FLOATING_MID - This setting considers valve_reverse[]
and cycle_time[]. Synchronization is performed at every restart and at
least once per day.
ONE_STAGE - Triac 2 is not used.
TWO_STAGE/THREE_STAGE - Triac 1 and 2 used (triac 1 and 2 both
ON for stage 3). When configured as multistage, cycle_time and
min_stage_off_time are considered.
PWM/THERMAL - Triac 2 is not used. Triac 1 operates as a pulse-
width modulated output, and the cycle time must be specified in
cycle_time[]. For PWM outputs, PwmZeroPosn and PwmFullPosn must
also be specified.

FLOATING This configuration variable specifies the output type to drive the
connected actuator for the output 2 (see above).
nciFcuConfig valve_reverse_0 Bit
DIRECT
REVERSE
0
1
DIRECT This configuration variable applies to only those outputs that have been
configured as FLOATING, PWM, or THERMAL and specifies the
direct/reverse operation of output 1.
nciFcuConfig valve_reverse_1 Bit
DIRECT
REVERSE
0
1
DIRECT This configuration variable applies only to those outputs that have been
configured as FLOATING, PWM, or THERMAL and specifies the
direct/reverse operation of output 2.
nciFcuConfig fan_interlock_0 Bit
NO
YES
0
1
NO This configuration variable configures an interlock between fan and
output 1 to provide equipment protection for electric heat or
compressor. fan_interlock_0=1 enables interlock, which guarantees
output1 to be driven only when the fan is running.
nciFcuConfig fan_interlock_1 Bit
NO
YES
0
1
NO This configuration variable configures an interlock between fan and
output 2 to provide equipment protection for electric heat or
compressor. fan_interlock_1=1 enables interlock, which guarantees
output2 to be driven only when the fan is running.
