Important: We can no longer update version 7.5 units
The update from version 7.5 or 7.6 is a manual process, and sometimes requires several tries. The update from 7.7 to version 8.0 is much more stable, and not likely to fail. This tutorial will help update a ThermaTouch to version 7.7.
These instructions require the ThermaTouch to be connected to the internet.
The total time required to complete these steps may be from 20-90 minutes.
These steps should be repeated until the unit updates to 7.7. It is common for a unit to require two tries before successfully updating.
