2 Suitable Mounting Locations Mount the Zone Panel Expander near the Main Panel. If desired, the expander panel can be mounted up to 500 feet from the main panel. The panel can be mounted in any orientation on a wall, stud, roof truss, or the return-air plenum. For appearance, mount the panel near the main panel for easy panel to panel wiring. Remove the panel cover and use the base as a template to drill mounting holes (see Figure 2). Attach the panel with appropriate screws.
3 Wiring the Panel Always turn off power to the heating/air conditioning system prior to installing or adjusting the Zone Panel Expander. Use the following general wiring instructions for all systems. Specific wiring will vary depending on the type of thermostats and dampers used for the installation. NOTE: Up to 2 wires can be inserted into each terminal position. To release wires, press down on top of wiring terminal and gently pull out wire(s).
