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. Attach the panel with appropriate screws. Use mounting anchors as needed for drywall or plaster installations.

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).

WIRE STRIP GUIDE

|

Wires should be stripped 3/8 inch minimum.

The expansion zones may be wired to either the top or bottom communication terminals on the main panel or to the top or bottom communication terminals on the expansion panel. This wiring flexibility allows the installer to choose the most flexible, cost effective wiring for the installation.
Each expansion panel must have a 5 Wire connection for proper communication. It is not necessary to use shielded wire for the panel to panel connection. 18 – 20 Gauge solid thermostat wire or similar is acceptable. When wiring the expansion panels be sure to connect the terminals from one panel to the next using the following terminal connections.

• Star Wiring All Zones Located at Main Panel
  

• Daisy Chain Zones Located Remote to Main Panel (Up to 500 Feet)
  

• Daisy Chain Zones Located Remote to Main Panel – Remote Panels Wired in Star Configuration
  

NOTE: To prevent possible interference do not run low voltage wiring along side 120 VAC wiring or magnetic ballasts.

Damper Wiring

Install the system dampers using the instructions provided by the manufacturer. Connect the dampers to the zone panel expander as shown for either a 2-wire or 3-wire damper. The sum of all dampers powered by the zone panel should not exceed 75 VA at 24 VAC. Use a slave relay if additional damper power is required.

ALWAYS PROVIDE DISCONNECT AND OVERLOAD PROTECTION AS REQUIRED

Transformer Wiring

Install the transformer using the instructions provided by the manufacturer. Size the transformer to the damper requirements. The zone panel has a built- in, self- resetting fuse. The maximum damper power per zone is 75 VA at 24 VAC. Connect the transformer to the zone panel as shown. NOTE: Additional dampers or dampers with a higher current draw will require the use of a separate slave relay.

ALWAYS PROVIDE DISCONNECT AND OVERLOAD PROTECTION AS REQUIRED

Zone Addressing

Use the following instructions to identify the zones on the zone panel expander. No other configuration is necessary on the zone panel expander. Carefully slide the dip switches to match the new zone numbers.

Use the open area provided on the expander panel to mark the new zone numbers. When setting the switches to identify the expander panel, use a pen or small screwdriver. Do not use a pencil, which may contain conductive material in the writing point.

Add Zones to Main Panel

The 4 Zone Expandable Panel can be expanded to up to 32 zones with four zones on the main panel and 28 total expansion zones. Additional zones must have power and communication wires to be recognized and controlled by the main expandable panel. To add additional zones, complete all wiring and start the main panel test mode.

Start the panel test mode to add additional zones:

1. Ensure all wiring is complete, zone addresses are set (section 4), and power has been applied to the main and expansion panels.
2. Press TEST for 3 seconds and release.
3. Press and release SELECT once for each new zone added. New zones must be added in blocks of two. NOTE: After second new zone is added, expander LED will change from red to green, and ZONE OK will appear in the main panel display.
4. If new zones do not appear, check wiring and ensure expansion zones have power.
5. Press HOLD FOR EXIT for 3 seconds to complete adding zones.

Operation

The Zone Panel Expander has built in LED’s to tell the installer and the system owner the current operating mode of the panel. Refer to the figure below and the following descriptions of the panel LED’s for operation information.

Error Conditions

The following messages will be displayed on the Main Panel if incorrectly addressed expansion panels are detected during expander configuration when the Main Panel is in the TEST mode.

Invalid Address on Expansion Panel
Displayed when an invalid address has been set on an expansion panel. This message will appear when an expander is powered up and wired to the communication terminals. To locate the expander panel with the invalid address, view the expander panel status LED. The status LED will be flashing red.

Duplicate Address on Expansion Panel
Displayed when a duplicate address has been set on an expansion panel. This message will appear when an expander is powered up and wired to the communication terminals. To locate the expander panel with the duplicate, view the expander panel status LED. The status LED will be flashing red. Change the expander switches as noted in section 4 to remove duplicate addresses.

The Main Panel continually monitors the status of the expansion panel(s) and will display the following message if communication is lost with a previously connected expander panel.

Communication Lost with Expansion Panel
This message is displayed if the Main Panel loses communication with an expansion panel. Check the wiring between the Main Panel and the expansion panel, and confirm that the addressing dip switches are configured properly.
