Connect the communication wiring from the wall-mount units to the controller in the manner shown in Figure 1.15.
The communication wire should be 2-wire, 18 gauge shielded cable with drain. Any color can be used. Be sure to
match "+" and "-" symbols on controller terminal blocks to prewired unit control terminal block (see Figures 1.17 and
1.18 on pages 26 and 27). Attach communication wire filters as shown in Figure 1.16.
Use separate conduits for
communication and supply wiring.
