On the Acurite display for my 5-in-1 Professional 01536), the lower right quadrant (Indoor) keeps flashing to the optional sensors. Since there are no optional sensors installed is there a way to make it stop doing that?
You should be able to turn off the auto cycle. In auto-cycle mode, the display will automatically cycle through indoor and each sensor’s data. Auto-cycle mode can be activated by pressing and releasing the “UP “ or “DOWN “ buttons until the “ half circle with an arrow“ indicator appears. Pressing the up and down arrow should disable that auto cycle. Thank you. Have a good day!
