KS 94 from West Control Solutions is a single loop controller that can be configured for on/off control, PID control, and motorized valve regulation. It has an output function that is also open for configuring for off position control, split-range control, and several 3-point combinations of switching/continuous control.
This device has control modes that include the set-point, set-point/cascade, and programmer which can be offset with set point. The effect of offset can be added to minimize standby set point or as a factor to oxygen correction or split load.
