Default Sensor Values for Trane® Standard Programs
If multiple sensors are associated with a controller that has a Trane® standard program, the controller
will automatically use the following values:

Referencing Individual Sensors
On the Controller Settings tab, under Wireless Sensor Configuration as shown in figure below, when
multiple sensors are desired and the Enable Wireless Space Sensor box is checked, the Analog Input
point Space Temperature Local will automatically use the reference wci.spaceTemp. The reference wci.
spaceTemp will always average all wireless space sensors that are associated to the controller and
display the average value in Space Temperature Local.
However, if using multiple sensors and the Enable Wireless Space Sensor box is unchecked, you can
reference an individual sensor to Space Temperature Local by changing the reference from wci.
spaceTemp to the new sensor's reference, such as wci.sensors.1.spaceTemp. This allows for the
individual values to be displayed on graphics or used in custom TGP2 programs.
Note: If you have multiple sensors and are creating points and references to see the individual values,

Space Temperature Local: This point will automatically use the average space temperature value
from all associated sensors.
Space Humidity Local: This point will automatically use the average humidity value from all
associated sensors.
Note: If a sensor value does not exist or is not valid, it will not be included in the average calculation.

Occupancy input: This point will show occupied if any associated sensor detects motion.

All user inputs from multiple associated sensors automatically follow a round-robin sequence where
the controller uses the value from the sensor that has transmitted most recently.
