A trend channel is activated by assigning a "Trend signal" to it.
Each trend channel can be assigned a plant-specific text with max. 20 characters via
operating line "Trend channel x".
The bus address of the room for which the room temperature is to be recorded can be
set via the "Geographical zone".
To acquire the outside temperature via bus, set the relevant "Outside temperature
zone".
The Y-axes can be scaled for each trend channel. Datapoints "Y-axis min" and "Y-axis
max" refer to the value display and must be set according to the expected signal range.
There is no trend display if the current values are outside the selected range!
A second trend channel can be shown via operating line "Selection extra channel". This
channel is displayed as a dotted line.
Only every second measured value is displayed for the extra channel; thus, the value to
be measured should be put on the main channel.
The Y-axis label only refers to the primary channel. The extra channel is displayed accord-
ing to its Y-axis settings. If the axes differ, a warning triangle appears next to the axis.
The trend channels can be called up via the following menu:
Main menu > Data acquisition > Trend channel 1...4
The trend channels are displayed with the text assigned to them.
When a trend channel is selected, the display immediately switches to the 24-hour
view. The select-and-push knob allows you to navigate between the different views.
