9.7.2 Set-point ramp and set-point step
You can define the type of temperature and humidity transitions for each individual program section.
“Ramp” mode: Gradual changes of temperature and humidity
The set-point of a given program section functions as the section’s start temperature. During the section’s
duration, the set-point gradually passes to the set-point of the subsequent program section. The actual
value follows the continually changing set-point.
If the last program section is in “ramp” mode and the setpoint shall change within this section, then you
must program an additional section (with the shortest possible section duration) to provide the target
temperature of the last program section. Otherwise, the setpoint would remain constant during the sec-
tion’s duration.
Programming in the “ramp” mode allows all kinds of temperature and humidity transitions:
•
Gradual changes of temperature and humidity
The setpoint changes its value gradually during the entered section duration. The actual value follows
the continually moving set-point at any time.
•
Program sections with constant temperature and humidity
The setpoints (initial values) of two subsequent program sections are identical; so the temperature
and humidity remain constant during the entire duration of the first program section.
•
Sudden changes of temperature and humidity
Steps can be programmed in ramp mode as temperature or humidity changes (ramps) that occur dur-
ing a very short interval. If the duration of this transitional program section is very short (minimum en-
try 1 sec), the temperature or humidity change will proceed rapidly within the minimum amount of time.
“Step” mode: Sudden changes of temperature and humidity
The set-point of any program section functions as the section’s target value. At the start of the program
section, the unit heats up or cools down and humidifies/dehumidifies the chamber with the maximum
speed to reach the entered value; and then it holds it for the remaining section time. Therefore the set-
point temperature remains constant for the section’s duration. These changes occur rapidly within the
minimum amount of time (minimum entry: 1 second).
Programming in the “step” mode allows only two kinds of temperature and humidity transitions:
•
Programming gradual changes of temperature and humidity (ramps) is impossible in the “step” mode
•
Program sections with constant temperature and humidity
The setpoints (target values) of two subsequent program sections are identical; so the temperature
and humidity remain constant during the entire duration of the first program section.
•
Sudden changes of temperature and humidity
The entered setpoint of the section is reached as fast as possible and then held constant for the re-
maining section duration.

In the field “Course” select the desired setting
“Ramp” or “Step”.
