12 TR50 - User Guide
Neutral Mode: With Display/ Without Display
The LED behavior of Neutral mode Temperature readings are shown below:
Threshold settings of LED color rings:
* These threshold parameters can be configured as per requirement. For example,
TVOC parameter threshold can be configured as Good (<500ppb), medium(500-
1500ppb),poor(>1500ppb) as per UBA study by the German Federal Environmen-
tal Agency. Just need to set the following two parameters (Take BACnet point as
an example): CfgAlarmTVOCHighLimit =500 CfgAlarmTVOCHighHigh
Limit =1500. There will be time delay (default 60 seconds) to stabilize the change
between different color.
