Example 1: Time-based set point for a temperature controller
The temperature should increase to 21 °C from 08:00 every day, and then to 23 °C for 5
hours from 12:00. The temperature should be controlled to fall back down to 18 °C from
17.00. Two time switches are defined for this purpose which are used in a
MF1: Formula
mathematical function. Using the mathematical function, an analog temperature set point
is thus available for a controller.
