Communication Wiring: Termination at the First Wall-Mount Unit
1. From the controller, extend the shielded cable through a separate conduit
and route to the provided terminal block next to the wall-mount control
board.
Note that the terminal block label is clearly marked “+” and “-”. These
connections are polarity-sensitive. Two-wire communication from control
board is prewired to terminal block. Make sure to match "+" and "-"
symbols on controller terminal blocks.
2. Connect the wires matching the terminal
designations (+/-) of the controller terminals.
Leave the drain wire loose.
3. Connect another cable in a similar
fashion (“daisy chain”) to route in
conduit to the second wall-mount unit.
Connect both drain wires with wire nut.
Maximum two wires per terminal.
