To set the dip switches in an 8 channel sensor, there are three dip switches with 8 different combinations.

DIP SWITCH FUNCTION
1 2 3 4
DOWN DOWN DOWN Channel 1
DOWN DOWN UP Channel 2
DOWN UP DOWN Channel 3
DOWN UP UP Channel 4
UP DOWN DOWN Channel 5
UP DOWN UP Channel 6
UP UP DOWN Channel 7
UP UP UP Channel 8
DOWN °F
UP °C

After you set the dip switches, you must always power down and up the remote sensor by removing and reinserting the batteries for the change to take effect.

Why do we do it this way instead of an 8 position switch? The reason is 8 position switches are much more difficult to implement, less reliable and takes up more space.
