Trend channel 1…Trend channel 2
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. Data points "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
adjusted range!
A second trend channel can be shown via operating line "Selection extra channel".
This channel is displayed as 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
according to its Y-axis settings. If the axes differ, a warning triangle appears next to
the axis.
Call up the trend channels via the following menu:
Main menu > Data acquisition > Trend channel 1...4 >
The trend channels are displayed with their assigned text.
If a trend channel is selected, the display immediately switches to the 24-hour view.
The press-and-turn button allows you to navigate between the different views.
