Heating circuit

11.5.2 Cooling curve

The cooling curve has the specific function of ensuring that

the heating circuit is cooled correctly relative to the target

room temperature and the outdoor temperature.

X Average outdoor temperature

Y Flow temperature

1 Cooling curve set via parameters (applicable when

target room temperature = cooling curve reference

room temperature)

2 Dew point limiting

3 Parameter: Cooling limit

4 Parameter: Outdoor temperature base point

5 Parameter: Flow temperature at base point

6 Parameter: Standard outdoor temperature

7 Parameter: Flow temperature at standard outdoor

temperature

8 Cooling curve calculated by controller (applicable

when target room temperature is greater than cooling

curve reference room temperature)

9 Cooling curve calculated by controller (applicable

when target room temperature is less than cooling

curve reference room temperature)

10 Cooling function active

11 Cooling function not active
