Diagram 3: NMT538 with Varec 9909 with bottom & vapor spot temperature
Note!
Since NMT538 is capable of accepting up to 16 elements for average temperature calculation,
the bottom & vapor spot elements can be used to expand its measuring range. In this case, the
bottom spot can be used as the #1 lowest position element for the connection to the brown wire
from the NMT538. If the average elements have already 16 input, ignore connecting neither the
bottom nor vapor spot element.
