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.
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.

Room Influence
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.
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.
