4. Communication Wiring
Connect the communication wiring from the wall-mount units to the controller in the manner shown in Figures 1.5,
1.6 or 1.7. 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 1.9 and 1.10 on pages 15 and 16). Attach communication wire filters as shown in Figures 1.5, 1.6 or 1.7.
Filters go inside the unit or controller box; they are shown out of unit for identification purposes only.
Do not run
communication wiring in same conduit as supply wiring. Route communication wiring and power supply wiring in
their own separate conduits.

In addition to the "daisy chain" method of connecting the communication wiring shown in Figure 1.5, the wall-mount
units can also be connected in the manner shown in Figure 1.6. If connecting wall-units this way, be sure to place
the communication wire filters in the positions shown in Figure 1.6. See Figure 1.7 for more information on the
correct placement of the communication wire filters depending on the wiring method used.
