Function heating acc. to DIN 4725 Part 4 (setting 1)
• Constant heating at 25°C on the start day and for the following
three days.
• Subsequently for another four days with the set maximum flow
temperature with a maximum limit of 55°C.
Maximum temperature setting = 40°C.
Progression of screed function over time with functional heating
Heating function for floor covering (setting 2)
The heating of the floor covering follows a preset temperature
profile.
Starting with 25°C on the first day, the requested temperature
rises by 5°C per day over the following days until the maximum
temperature of the heating circuit is reached. After that the
setpoint temperature is reduced with the same stepping until the
base point of 25°C is reached again.
Maximum temperature setting for the heating circuit = 40°C
1. day: constant heating at 25°C
2. day: constant heating at 30°C
3. day: constant heating at 35°C
4. day: constant heating at 40°C
5.-15. day: constant heating with max. flow temperature
16. day: reduced heating at 35°C
17. day: reduced heating at 30°C
18. day: reduced heating at 25°C
