Configurator
Program blocks are stored in the library without I/Os. Use the auto-create and auto-connect functions to create I/Os and/or to connect them to the interface blocks, e.g., R_A, CMD_B. Alternatively, take the I/Os from the folder containing the predefined I/Os in the library and/or from the plant and connect them to the interface blocks.
Calculates the setpoint for the flow temperature based on a heating curve.
It uses the function block HVAC and value objects for showing its values on BACnet.
You must set:
- two values for the outside temperature
- two corresponding flow temperature setpoints
- one radiator exponent
There are configuration values for the minimum and the maximum flow temperature setpoints.
