Summer compensation takes full effect at this outside temperature (920). The comfort
setpoint is not affected by any further increase in the outdoor temperature.
This setting determines the maximum permissible increase in the comfort setpoint.

A low limit can be defined for the cooling flow temperature.
The limit curve is determined by defining two fixed points.
There is also a low limit for the resulting flow setpoint, which must not fall below 5 °C.
This defines the lowest permissible flow temperature at a composite outside
temperature of 25°C/25°C.
If there is no valid outside air temperature available, the controller uses the value
"Flow setpoint min TA = 35°C"
