Using the Application

For operating the application, respectively one example of a TO170A and a
OP3 are delivered in this application. How to use the application is
explained for two cases.
On application case uses many different absolute time switches plus
summer/winter time changeover, and is displayed at the HMI interface of
the TP170A (Chapter 6.1).
The second case includes several relative time switches as a pulse chain
and only two absolute time switches. This application case is explained
using the example of the OP3 (Chapter 6.2).
Note
How to use several time switches is described in Chapter 9.
Both application cases are included in the download on top of the "base
project", and can be used as a basis for your own configuration.
