Assortment / System Description

The "Energy indicator" function is used by the OZW772 web server to read

predefined data point values from the devices on the KNX bus and to compare

them with energy-related so-called "green limits".

This means that the data points are monitored to ensure their "green limits" are

observed. The result is presented by the "Energy indicator" in the form of a leaf.

Note: The "green limits" are only used in connection with the "Energy indicator" function. They do not

correspond to process- or security-related limit values which, in the case of limit value

violations, trigger fault status messages, for example, or shut down the plant in an emergency.

Data point value is within its "green limit". So, with regard to energy usage, the

value is within its "green range": Leaf appears in green, pointing upward.

Data point value exceeded its "green limit". The value is no longer within its "green

range": Leaf appears in orange, pointing downward.

the data point value "Comfort heating setpoint" and its "green limit".
