Program/Timer Segment Types
In program ON condition each segment consists of a controlled ramp rate to a target set
point followed by a dwell at that set point. These values can be set by the user.
a. Target set point
Target set point will ramp from the current value of the measured temperature to the
target set point value based on ramp rate.
b. Ramp Rate
A Ramp segment provides a controlled change of set point from an original to a target set
point. The duration of the ramp is determined by the rate of change specified. The
segment is specified by the target set point and the desired ramp rate. The ramp rate
parameter is presented in engineering units (°C, °F, Eng.) per real time units (Seconds,
Minutes or Hours). If the units are changed, all ramp rates are re-calculated to the new
units.
c. Step
The set point changes instantaneously from its current value of the measured
temperature to a new value at the beginning of a segment. Step can be achieved by
turning off Ramp rate. A Step segment has a minimum duration of 1 second.
d. Dwell
