9.2 Status and actual displays
You can obtain information about the current state of the device/system/process as follows:
Operating status display via LEDs
The LEDs on the Central Interface Module (CIM) as well as on the Power Output Module
(POM) provide information about the current operating status of the device or the heating
system.
For detailed information on the meaning of the LED displays, see Section "LED operating
display for CIM (Page 179)" and Section "LED operating display for POM (Page 180)".

Power output control

9.3.1

Half-wave control

Half-wave control can be parameterized for activating the heating elements. This
parameterization is performed for each POM and applies to all channels of the POM.
Operating principle of half-wave control
The power outputs are controlled in half-waves: For each half-wave, the controller supplies
On/Off information to the triac and this switches as specified.
Figure 9-1
The setpoints for controlling the power outputs lie within a value range of 0 % to 100 %
(reference value: 100 half-waves).
