the L1 limit is higher than the L2 limit) for 2", after which L1 is displayed again.
CORRECTING THE SET VALUES
If programming is not carried out within 60", the program resets automatically reverting to the previously stored values and
the channel temperature is displayed.

Each TCK temperature sensor has a red (-) and a yellow (+) conductor (ASTM E 608 regulations).
On page 9 you will find the positions on the terminal block of the connecting cables for both models.
