Set room influence
With weather-dependent control, the feed
temperature can be adjusted if there is a large
divergence between the room temperature and
the setpoint temperature.

Setpoint value of room temperature = T

Actual value of room temperature = T

Tv
= PI (T

)
Example: T
R set
= 20 °C T
R act
= 18 °C PI = 3
∆
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.
Set maintenance period
With maintenance, it is a question of a
"reminder function".
