Suitable Mounting Locations
Mount the Zone Panel near the HVAC equipment. The panel can be mounted in any orientation on a wall,
stud, roof truss, or the return-air plenum. For appearance, mount the panel level. Remove the panel cover
and use the base as a template to drill mounting holes (see Figure 2). Attach the panel with appropriate
screws. Use mounting anchors as needed for drywall or plaster installations.

Damper Wiring
Always turn off power to the heating/air conditioning system prior to installing or adjusting the zone panel. Wire
the entire panel before applying transformer power.
Use the following general wiring instructions for all systems. Specific wiring will vary depending on the equipment
and type of system (conventional or heat pump).
Install the system dampers using the instructions provided by the manufacturer. Connect the dampers to the zone
panel as shown for either a 2-wire or 3-wire damper. The sum of all dampers powered by the zone panel should
not exceed 100 VA at 24 VAC. Use a slave relay if additional damper power is required.
ALWAYS PROVIDE DISCONNECT AND OVERLOAD PROTECTION AS REQUIRED
