8.10.2 Processing an external demand with a 0 to 10 V signal
The controller (= primary controller) can process analog external demands. The 0 to 10 V signal
is interpreted as a flow temperature demand of 0.0 to 120.0 °C, i.e. the flow temperature de-
mand is 12 °C/V.
The set point of the downstream secondary controller is read at the analog input UI1 and com-
pared with the controller's own flow temperature set point. The higher of the flow temperature
set points plus 'Set point boost of pre-control loop' is used by the controller to regulate the flow
temperature. The 'Set point boost of pre-control loop' parameter improves the control behavior
of the downstream heating circuit instruments and compensates for any loss in capacity.

8.11 Demand requested with a 0 to 10 V signal
The controller can request its maximum flow set point (with boost, if required) by issuing a 0 to
10 V signal. The output UO1 is used.

8.12 Forwarding the measured outdoor temperature
The controller can make the measured outdoor temperature available to a downstream control-
ler. The 'Lower transmission range value, outdoor temperature' and the 'Upper transmission
range value, outdoor temperature' is assigned to a 0 to 10 V signal. The downstream controller
uses the outdoor temperature to determine the flow rate temperature.
