I have an ADC T2000 and want to know how to check what the firmware version is. If its not current how do I get an update
In order to confirm your ADC T2000’s firmware version, while the T2000 mode is off, hold the up arrow button for about 3 seconds. You should see a number displayed (Ex. X.XX) along with the symbols for both heat and cool. This is the firmware version.
Currently, there is no way to upgrade the ADC T2000’s firmware.
