info

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.

Function

Provides supply air humidity setpoints.

They are limited to a minimum and maximum.

info

The input pins [Hu] and [HuSu] are there only to ensure the compatibility to HuCasCtr21 and are not interconnected internally.

info

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 humidification and dehumidification to the supply air setpoints and limits them.
