• Flow setpoint limitation
It is possible to assign a lower limitation to the cooling flow temperature.
The limitation line will be defined by two reference points. In addition, the resulting flow setpoint
will have a lower limitation and may not be less than 5°C.
– Flow temperature setpoint minimum at OT 25°C: Determines the lowest flow temperature for
a composite outdoor temperature of 25°C.
– Flow temperature setpoint minimum at OT 35°C: Determines the lowest flow temperature for
a composite outdoor temperature of 35°C.
WARNING
If no outdoor temperature is available, the controller will use the "Minimum flow setpoint at OT
= 35°C" parameter.
