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.

Wiring the Panel

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).

NOTE: Up to 2 wires can be inserted into each terminal. To release wires, press down on top of wiring terminal and gently pull out wire(s)

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. 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.

Thermostat Wiring
Install the system thermostats using the instructions provided by the manufacturer. Connect the thermostats to
the zone panel as shown. Do not mix conventional and heat pump thermostats on the same system. You can mix single stage and multi-stage thermostats as long as they are all conventional or heat pump.

Transformer Wiring
Install the transformer using the instructions provided by the manufacturer. Size the transformer to the damper requirements. The zone panel has built-in, self-resetting fuses. The maximum damper power per panel is 100 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.

Conventional Equipment Wiring
Connect a conventional heating system to the zone panel as shown. For a single stage heating and cooling system, the 2nd and 3rd stage connections are not used. For a system using a dual transformer, remove jumper Rc to Rh (see Figure 3, page 4). Make sure the neutrals (common) are connected. ALWAYS PROVIDE DISCONNECT AND OVERLOAD PROTECTION AS REQUIRED

Heat Pump Equipment Wiring
Connect a single or multi-stage heat pump system to the zone panel as shown. ALWAYS PROVIDE DISCONNECT AND OVERLOAD PROTECTION AS REQUIRED

Configuration

Use the following instructions to configure the zone panel. The zone panel is factory set for a 1 Heat / 1 Cool Conventional System with Conventional Thermostats (Heat Call on W, Cool Call on Y). If the zone panel is installed on other systems, you will need to make configuration changes described in this section.

To start configuration:

1.  Press SETUP and hold for 3 seconds. 10
2. The panel backlight will turn on and the display will change.
3. Change setting if needed by pressing SELECT.
4.  To save and advance to the next setting press the NEXT button.
5. Repeat steps 3-4 as necessary.
6. Press HOLD FOR BACK for 3 seconds to go back a step.
7.  Press HOLD FOR EXIT for 3 seconds to exit setup menu.

System Checkout

To start the panel Test Mode:

1.  Press TEST for 3 seconds and release
2.  Press SELECT to turn the test on and off
3. Press NEXT to move on to the next test
4. Press HOLD FOR EXIT for 3 seconds to exit test mode System Checkout.

Heating Stage(s) Test ON or OFF
This test turns on all heating stages (including O-B for heat pump configurations) the system fan, and commands all dampers to open. The heating stages will by energized by the type of system configured in the installer settings. A heat pump configuration will have all compressor calls and Auxiliary Heat. A conventional configuration will call all conventional heating stages. Press SELECT to Test or NEXT to advance to the next test

Damper Control Test PO or PC
This test powers all dampers open or closed. Press SELECT to test or NEXT to return to the first test.

Operation

The Zone Panel has LED’s and a built-in display 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.

HEAT CALLS
Check the panel LED if it is necessary to determine exactly which zones are calling for heat operation. If Auxiliary Heat or Emergency Heat calls are active, the display will replace heat calls with Auxiliary or Emergency Heat Calls.

To select Emergency Heat from the main panel:

1.  Press and release the EM HEAT button located below the main display.
2. To stop Emergency Heat, press the EM HEAT button again.
3. The display will update from EM HEAT CALLS to HEAT CALLS and COOL CALLS will return.

Error Conditions

The zone panel continually monitors various components of the zone system and will display a message when the following monitored conditions are detected.

COOL DISABLE
To enable cooling, turn Emergency Heat Off at the panel and/ or the priority thermostat calling for emergency heat and make a call other than emergency heat from the priority thermostat.
