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.
Performs temperature control for the hot water flow temperature.
The setpoint for the hot water temperature control is increased by a small offset defined by an analog configuration value, and the slightly higher setpoint for the hot water temperature is sent to the energy generator(s).
This program block has the following optional functions:
Option: Hot water storage tank
Controls the charging state of a hot water storage tank (with 4 temperatures) (CrgReqStk21).
Option: Outside air temperature (1xAI)
Creates an analog input for outside air temperature and reads its signal.
