Performance after completing the program:
The controller changes to Idle Mode. The heating and the cooling are inactive; the chamber approximates
ambient temperature. The fan is off.
9.2 Selecting between set-point ramp and set-point step
Temperature set-points always refer to the start of a program section, i.e., at the beginning of each pro-
gram section the entered temperature set-point is targeted. During program section operation, the tem-
perature gradually 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 transitions.
•
Gradual temperature 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 value (X) follows the continually moving
set-point (W) at any time.
• Program sections with constant temperature
The initial values of two subsequent program sections are identical; so the temperature remains con-
stant during the whole time of the first program section.
• Sudden temperature changes “set-point step”
Steps are temperature changes (ramps) that occur during a very short interval. A section with a differ-
ent 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 change will proceed rapidly with-
in the minimum amount of time.

Figure 8: Possible temperature transitions
The following chapter offers examples of programming a set-point ramp and a set-point step.
9.3 Program entry as set-point ramp or as set-point step
In order to avoid incorrect programming, we recommend plotting the temperature profile (chart template in
chap. 0) and entering the values into a table (template in chap. 9.10).
The controller provides 8 operation lines that can be activated or de-activated for each program section.
Operating contact 1 serves to control the bedew protection (chap. 10). The other operation lines are non-
functional.
