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.
Provides supply temperature setpoints.
The setpoints are limited to a minimum and a maximum.
You can select the calculation method of the temperature setpoint for the energy recovery. It is either equal to the heating or cooling supply temperature setpoint and depends on the present direction of the control action (preset), or equal to their average.
The input pins [T] and [TSu] are only present to ensure the compatibility to TCasCtr21 and are not interconnected internally.

This module is called controller, however it doesn't contain a controller. This module is an alternative to a module with a cascade controller. It connects the plant's setpoints for heating and cooling to the supply air setpoints and limits them.
