The "Energy indicator" function is available in web server OZW772… as of version
4.0. The following devices are supported:
• Synco 700: RMU7x0B, RMH760B, RMK770 (as of version 2.0),
RMS705B,
RMB795B

• Room thermostats: RDF301, RDU341, RDGx00KN
The web server uses the "Energy indicator" function to read selected data point
values from the bus devices and to compare the values to energy-related limit val-
ues, or so-called "Green limits".
The data points are also monitored for adherence to the "Green limits".
As a result, the "Energy indicator" is displayed in the form of a tree leaf.
The "Green limits" are used only together with the "Energy indicator" function. They
do not represent process or safety limit values which trigger e.g. fault messages or
turn off the plant in the event of limit violations.
The "Energy indicator" can send its information periodically (adjustable via web
server) to a maximum of 2 e-mail recipients.
"Green leaf"  Green tree leaf, leaf pointing up.
• The "Green leaf" symbol indicates that a data point value has not exceeded
its "Green limit", i.e. the value is within a "green" range in terms of
energy consumption.
"Orange leaf"  Orange tree leaf, leaf pointing down.
• The "Orange leaf" symbol indicates that a data point value has exceeded its
"Green limit", i.e. the value is outside a "green" range in terms of energy con-
sumption.
The "Energy indicator" function is based on standard EN 15232 "Energy efficiency
in buildings".
