the setpoint temperature.
Offset supply temperature
Set room influence
Setpoint value of room temperature = T
Actual value of room temperature
∆ Tv = PI (T
R set
Example: T = 20 °C T
R set
∆ Tv = 3 x ( 20 °C - 18 °C) = 6 K
Result: The feed temperature is increased by 6 K.
The higher the selected room influence, the
greater the influence of the room temperature
on the feed temperature.
