There are two configurations used for temperature averaging:
- Setting up a thermostat that reads separate sensors and averages the temperature itself using its software
- Wiring sensors in averaging setup, series/parallel
Temperature averaging is possible with Trane sensors. The new Version 5.3 Software release for Wi-Fi thermostat models
XL824,
XL850, and
XL1050 allows multiple temperature sensor averaging for non-zoned systems.
When adding
ZSENS930AW00MA wireless temperature sensors to a connected control running version 5.3 software be sure to download the new
Installer guide for the ZSENS930AW00MA sensor.

Unlike Controls running on Software Versions earlier than 5.3, the temperatures of the onboard sensor and wireless sensor can be averaged equally without disabling the internal sensor.
Below is the Version 5.3 Sensor Application Matrix.
