Replace high voltage shield after wiring is completed.
Low Voltage Connections
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 conduit connection using
liquid tight cord and before being attached to the board. If Modbus
communication is being used, a water tight type conduit may be
used instead.
Liquid tight cord grip -
snaps into conduit
opening at the top of
the controller.

If solenoid will use the same voltage as controller, one leg of
incoming power supply (L1) for the liquid line solenoid should
be connected to the common terminal of the liquid line
solenoid relay (5). The other leg of incoming power (L2) for the
solenoid should be connected directly to one of the solenoid
leads (not shown). The remaining lead for the solenoid should
be connected to the NO (normally open) terminal of the liquid
line solenoid relay (4).
Proper wiring practices must be followed. Local wiring
codes take precedence over any information in this
bulletin.
