This computer does not have a drawing program so with words:
You have 4 TC sensors. North, South, East, and West.
Wire N and S in series. This makes N+S read 2x higher than normal.
AND
Wire E and W in series. This makes E+W read 2x higher than normal.
Wire (N+S) and (E+W) in parallel. This cuts the readings in half.
__________________________________________________
Method two:
Wire N and S in parallel. This makes N//S read 1/2x.
AND
Wire E and W in parallel. This makes E//W read 1/2x.
Wire (N//S) and (E//W) in series. This doubles the readings.
-------------------------------------------------------------------------------
This is about the same as adding the 4 reading up and dividing by 4. (average)
