Temperature sensor - The temperature sensor
terminal is located on the cover’s circuit board
and is permanently attached. The temperature
sensor input consists of the right two terminals.
Although the terminals are labeled ‘+’ and ‘ - ‘ the
sensor is not polarized and may be connected in
either orientation.
The sensor should be fed through the top con-
duit connection using liquid tight cord and

conduit maybe used instead.
