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.
Figure 2
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 (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.
Max. damper VA per Zone 50 VA @ 24 VAC

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.
ALWAYS PROVIDE DISCONNECT AND OVERLOAD PROTECTION AS REQUIRED
Conventional Equipment Wiring
NOTE: For a heat pump system, see Section 3.5.
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.

System Checkout
After the wiring and configuration is complete, built in automatic zone panel tests may be used to verify equipment, damper, and panel operation.
To start the panel Test Mode:
- Ensure all wiring is complete and power has been applied to the main and expansion panels
- Press TEST for 3 seconds and release
- Press SELECT to turn the test on and off
- Press NEXT to move on to the next test
- Press HOLD FOR EXIT for 3 seconds to exit test mode
The following tests are available in Test Mode:
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.
Cooling Stage(s) Test ON or OFF
This test turns on the cooling stage (including O-B for heat pump
configurations), the system fan, and also commands all dampers to open. Press
SELECT to Test or NEXT to advance to the next test.
Fan Stage(s) Test ON or OFF
This test turns on the fan and commands all dampers to open. 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.

In addition to LED’s, the zone panel has a full function built-in backlit display panel that provides information on the current operations of the zone panel. When the zone panel is running in normal operation, the display is updated continuously to show the system operating parameters. The system will show the following status screens on the display.
HEAT CALLS
Number of heat calls currently being serviced. 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.
COOL CALLS
Number of cool calls currently being serviced. Check the panel LED if it is
necessary to determine exactly which zones are calling for cooling operation.
FAN CALLS
Number of fan calls currently being serviced. Check the panel LED if it is
necessary to determine exactly which zones are calling for Fan Operation.
NOTES: When no zones are calling, the panel will command all dampers to open.
- For maximum energy conservation, a purge will occur at the end of each call.
- No calls will be answered until the purge is complete.
- Equipment staging is automatic based on time.
Emergency Heat Selection (Multi-stage Heat Pump Systems Only) Emergency Heat can be selected at the main panel or from a Heat Pump Thermostat wired to the main panel. No cooling calls will be answered if emergency heat is switched on.
To select Emergency Heat from the main panel:
- Press and release the EM HEAT button located below the main display.
- The display will update from HEAT CALLS to EM HEAT CALLS and will show COOL DISABLE to indicate that no compressor calls will be answered.
- To stop Emergency Heat, press the EM HEAT button again.
- The display will update from HEAT CALLS to HEAT CALLS and COOL CALLS will return.
To select Emergency Heat from a thermostat
-
Set Emergency Heat Thermostat to Emergency Heat switch position (only one thermostat can control Emergency Heat)
NOTE: Configuration setting number 16 in section 4 selects which thermostat is used to activate Emergency Heat. -
Raise heat setting on Emergency Heat Thermostat to create Emergency Heat call.
-
The zone panel display will update from HEAT CALLS to EM HEAT CALLS and will show COOL DISABLE to indicate that no compressor calls will be answered.
-
To stop Emergency Heat, set the Emergency Heat Thermostat to a non-emergency heat position or lower the temperature on the Emergency Heat Thermostat to end the emergency heat call.
-
The zone panel display will update from EM HEAT CALLS to HEAT CALLS and COOL CALLS.
NOTE: Activating Emergency Heat Mode disables cooling calls from all zones and answers all heating calls with Emergency Heat.
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
Cooling is disabled when Emergency Heat has been selected on a heat
pump system
Selecting emergency heat from a thermostat (See Installer Option 16) in heat
mode will disable compressor cooling in all zones. 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.
OUTDOOR SENSOR BAD
Displayed when an error has been detected with the outdoor sensor. This error
must be corrected by servicing the zone panel outdoor sensor. If the outdoor
sensor is not operating correctly, the zone panel will not use outdoor balance
point control for heating calls.
Limited Warranty
When installed by a professional contractor, this product is backed by a 5 year limited warranty. Limitations apply. For limitations, terms and conditions, you may obtain a full copy of this warranty:
