9.4 Selecting between “set-point ramp” and “set-point step”
Set-points always refer to the start of a program section, i.e., at the beginning of each program section
the entered “set-point” is targeted. During program section operation, the temperature or humidity gradu-
ally passes to the set-point entered for the next section.
By appropriate planning of the program section timing, you can enter all kinds of temperature and humidi-
ty transitions:
•
Gradual temperature / humidity changes “set-point ramp”
The set-point changes its value gradually while proceeding from one program section to the next one
during the programmed section length. The actual temperature or humidity value (X) follows the con-
tinually moving set-point (W) at any time.
• Program sections with constant temperature / humidity
The initial values of two subsequent program sections are identical; so the temperature or humidity
remains constant during the whole time of the first program section.
• Sudden temperature / humidity changes “set-point step”
Steps are temperature or humidity changes (ramps) that occur during a very short interval. A section
with a different set-point follows two program sections with an identical set-point. If the duration of this
transitional program section is very short (minimum entry 1 sec), the temperature or humidity change
will proceed rapidly within the minimum amount of time.
Figure 17: Possible temperature or humidity transitions
The following chapter offers examples of programming a “set-point ramp” and a “set-point step”.
