Between the years 2022 and 2023, there was a technical problem with the factory tester that resulted in the incomplete download of the electric heat element when operating in the auto mode.
Despite the correct configuration of the units, the electric heat feature did not function unless it underwent manual testing.
To resolve this issue, please follow these steps: connect the Rover tool, access the configuration settings, change the electric heat to 2 stage, and then initiate the download process by clicking on the appropriate button.
Afterward, revert the configuration back to single stage and initiate the download process again.
By following these steps, the issue will be resolved and the electric heat function will operate correctly.
