display.
2. Press the ¿ or ¯ buttons until [tune] is shown in the top display. This option
will perform an auto tune on both channels (i.e. Heat and Cool outputs) when
selected. You can also optionally choose to tune only the [pid1] or [pid2]

3. Press the ˆ or the ‰ button until the display returns to the “Home” position. This
will start the Auto Tune process.
