4.8.3.2 PI control switching (PWM)
If the control value is set as switching PI control (PWM), the following setting options are available
(here: controller type heating):
Figure 23: Settings - PI control switching (PWM)
The PWM control is a further development of the PI control. All settings possible for PI control can
also be made here. In addition, the PWM cycle time can be set.
The following table shows the settings for switching PI control:
