3. General information on the message concept of
the controller
The controller is designed to display pending messages (indications or faults) to the
user. Especially when using the controller with a BMS, it is important to interpret
pending messages correctly and to be able to initiate any necessary measures in a
targeted manner.
To simplify the display of messages, so-called "HMI statuses" have been added to
all subcomponents of the controller. With the help of these HMI statuses, a possible
cause of error can be narrowed down and the error weighting identified. Please read
the chapter "General information on HMI statuses of the controller" for a detailed ex-
planation of HMI statuses. An HMI status can also be used to identify any boiler mal-
functions (see chapter "General information on boiler malfunctions").
Figure 3-1: Notification Concept of the Controller
Since the HMI statuses can only be used for a rough assessment of the error and
often more detailed information is required for the initiation of a suitable measure,
there are additional Modbus TCP registers which make the pending message identi-
fiable via a message key. For this please refer to chapter "General information about
the evaluation of current messages at the controller".
Note: If the connected boiler is in malfunction or manual mode, the controller will not
send any heat requests to the boiler. As soon as the boiler is ready for operation
again, the boiler is controlled according to the specifications.
