From the controller, extend the shielded cable through a separate conduit
and route to the provided terminal block next to the wall-mount control

control board is prewired to terminal block. Make sure to match "+" and "-"
symbols on controller terminal block.
2.
Connect the wires matching the terminal
designations (+/-) of the controller
terminals. Leave the drain wire loose.

Connect another cable in a similar
fashion ("daisy chain") to route in
conduit to the second wall-mount unit.
