Using a microSD card for setup, data logs and software upgrades
Use a microSD (secure digital) card to save setup time by loading Installer Setup
settings, Dealer Information, Holiday Schedules, and Custom Reminders to multiple

use the microSD card to upgrade the thermostat software.

thermostat software.
2 Connect a
microSD USB Adapter to your
computer to download the file(s).
3 After the file(s) are downloaded, remove the
microSD card from the adapter and insert

2 Select the item to load or save.
3 Follow the prompts on the screen.
