3.1 General information on HMI Status of the control device

An HMI status can be used to determine the current status of the controller and its
components. Each software component in the controller has such an HMI status.
This shows the current status of the respective component via five possible states.
As soon as one of the software components detects an irregularity in control opera-
tion, the corresponding HMI status is set. The higher-level software component rec-
ognizes the HMI status, adds to it if necessary and also passes it on to its higher-
level software component until the respective status has reached the highest soft-
ware component level. The principle of passing on the HMI status allows the soft-
ware component that originally influenced the HMI status to be reliably identified and
the exact cause of the error to be analyzed.
Five HMI statuses are available within the controller, which use a color assignment:
HMI Status
OK
Warning
Critical
Error
Unknown
Note: Only the colors green/blue, yellow and red are displayed on the hardware
LED on the controller.

3.2 General Information on Boiler Malfunctions

In addition to the HMI status of individual software components of the controller, the
heat generator provides additional information on operating messages. The mes-
sage classes of the boiler influence the HMI status of the corresponding component
in the controller. There are three different message classes:

Meaning
The system / component is
working properly.
A deviation from the normal
state has been detected on the
system/component, e.g. man-
ual operation has been acti-
vated or the boiler has too high
a flue gas temperature.
The system/component can
currently still be operated, but
timely intervention is required.
The system / component has a
malfunction. An intervention is
required.
The state of the system / com-
ponent cannot be determined.
