Pd oFSt
Control Probe Pulldown
Offset
The difference in temperature between the control
probe value and the average compartment
temperature that determines when the control system
changes from pull down mode to steady state operation.
This can be useful to adjust if the average compartment
temperature has an undershoot or overshoot relative
to set point during pull down mode. This offset is also
used on some refrigerator models as a response to door
openings.
