The temperature sensor assembly comes with a factory installed lithium battery. The procedure
below describes how to replace the battery when needed. Millennial Net recommends using
the following replacement battery type:
DigiKey Part Number: P189-ND (phone: 1-800-DIGI-KEY).
To replace the battery (see Figure B-6):
1. Use an Allen wrench to turn in the two set screws holding the cover to the base and
remove the cover.
2. Turn the power switch OFF.
3. Remove the screws (2) securing the terminal board to the base and lift the terminal up
and off the base.
4. Replace the battery—located on the bottom of the terminal board—with the
recommended battery type, observing polarity (+ side of battery to + side of holder).
5. Turn the power switch ON.
6. Reinstall the terminal board, replace assembly cover, and back out the two cover set
screws to secure the cover in place.
