Flow Setpoint Limitation
LINE FUNCTION
923 Flow temp setpoint min at OT 25°C
924 Flow temp setpoint min at OT 35°C
It is possible to assign a lower limit to the cooling
flow temperature.
The limitation line will be defined by two reference
points. In addition the resulting flow setpoint will
have a lowerlimit and may not be less than 5 °C.
Flow temp setpoint min at OT 25°C
Determines the lowest flow temperature for a
composite outdoor temperature of 25°C.

LINE FUNCTION
928 Room influence
When using a room temperature sensor there are 3
different types of control to choose from.
SETTING CONTROL TYPE
- - - % Simple control according to outdoor conditions *
1...99 % Control according to outdoor conditions with room influence *
100 % Control according to room temperature only
Requires the connection of an outdoor sensor
*
„
Simple control according to outdoor
conditions
The flow temperature is obtained from the
composite outdoor temperature on the basis of the
cooling characteristic.
Flow temp setpoint min 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 "Min. flow setpoint at OT= 35°C"
parameter.
Flow temp
setpoint
2 ° 5 C
This type of control requires the cooling curve to be
properly adjusted, as the control does not take the
room temperature into account for this adjustment.
