DUTY_COEFF
Direction Bidirectional
Binding
None
Type Floating
point
Value range
0
Units None
Description
CLD only; the temperature coefficient slope factor
Usage
Used to compensate the output for variations in ambient temperature. This
temperature is measured by monitoring the block temperature controller's duty cycle,
which varies as it keeps the block temperature constant.

Value range
0-100
Units Percent
Description
NDIR and PMD only; minimum duty cycle for the case fan
Usage
The fan will not run if the duty cycle is set less than 50%, so this variable is used to
make sure that the algorithm does not try to set the duty cycle too low at start up.
