Wiring an Equipment Touch to the controller
A single Equipment Touch is the only device you can wire to the controller's Rnet port. You can use a 2-conductor
cable instead of the standard 4-conductor Rnet cable and follow the instructions below.
The Rnet communicates at a rate of 115 kbps.
For complete Equipment Touch installation instructions including wiring diagrams, see the Equipment Touch
Installation and Setup Guide.
1 Turn off the controller's power.
2 Partially cut, then bend and pull off the outer jacket of the cable. Do not nick the inner insulation.
3 Strip about .25 inch (.6 cm) of the inner insulation from each wire.
4 Wire the controller's
and
terminals to the terminals of the same name on the Equipment Touch's
connector.
If using shielded wire, connect the shield wire and the ground wire to the
terminal.
5 Turn on the controller's power.
6 Turn on the Equipment Touch.
