Let’s first recall the three phases of a challenge.
Here are the set temperature variations during the three phases:

How to determine the set temperature at the end of a challenge:
Note: The gradual setpoint variation of each phase is divided into stages. The following examples will help you better understand these stages as well as the impact of your programs on a challenge.
Example 1
Progression of the challenge
This table allows you to see in detail the length of each stage. Note that the temperature varies by 0.5°C at a time during the reduction phase, and by 1°C during the recovery phase.
Example 2:
Planned programs
Note: When one of your programs starts at the same time as a new stage change during a challenge, the set temperature of your program will happen just before the next stage change. Thus, the set temperature of your program will be adjusted according to the temperature variation planned for the stage in which the program is executed.
Progression of the challenge
This table allows you to see in detail the length of each stage and the temperature variations. Note that starting from the time a program is scheduled to start, the set temperature (which will vary gradually, depending on the phase of the challenge) is the one required by the program.
*Temperature programmed for 6:30 a.m.: 20°C
The program’s temperature (20°C) is executed just before the end of stage 4. Since the temperature variation at this stage is +1° C, the set temperature will be 21°C (20°C + 1.0°C = 21°C).
**Temperature programmed for 8:15 a.m.: 19°C
The program’s set temperature (19° C) is executed during stage 8. Since the temperature variation at this stage is -2°C, the set temperature will be 17°C (19°C - 2.0°C = 17°C).
Example 3:
Progression of the challenge
This table allows you to see in detail the length of each stage. Note that the temperature varies by 0.5°C at a time during the reduction phase, and by 1°C during the recovery phase.
Example 4:
The programs are planned as follows:
Progression of the challenge
This table allows you to see in detail the length of each stage and the variations in temperature. Note that starting from the scheduled time of the start of the program, the set temperature (which will vary gradually, depending on the phase of the challenge) is the one required by the program.
*Temperature programmed for 4 p.m.: 21°C
The set temperature of the program (21°C) executes during phase 3. Since the temperature variation at this stage is +1.5°C, the set temperature will be 22.5°C (21° C + 1.5 °C = 22.5 °C).
**The temperature programmed for 7:30 p.m.: 23°C
The set temperature of the program (23°C) executes during phase 8. Since the temperature variation at this stage is -1.5°C, the set temperature will be 21.5°C (23° C - 1.5°C = 21.5°C).
