Trend channel 1 … Trend channel 4
A trend channel is activated by assigning a "Trend signal" to it.
Explanation on the
settings
Each trend channel can be assigned a plant-specific text with max. 20
characters via operating line "Trend channel 1..4".
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. "Y-axis min" and "Y-axis max"
refer to value display and must be set as per the expected signal range. There is
no trend display if the current values are outside the adjusted range!
You can show a second trend channel via "Selection extra channel".
This channel is displayed as a dotted line.
As only every second measured value is displayed for the extra channel, the
value to be measured should be put on the main channel.
Notes on the
extra 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 is
displayed next to the axis.
