Suitable Mounting Locations
Mount the 3 Zone Control Panel near the HVAC equipment (see Figure 2). 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 6.5” apart (see Figure 3). Attach the panel with appropriate screws (not included). 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 3 Zone Control 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).
Damper Wiring
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 35 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.
- Use only single stage conventional thermostats.
- Wiring to the C terminal is required only for thermostat power.
- E terminal at thermostat 1 is for connecting an external emergency heat switch.
External Emergency Heat Switch
For heat pump systems requiring an external emergency heat switch, connect as shown.
Supply Air Sensor Wiring
Install the supply air sensor in the supply air plenum at least 2-3 feet after the heat exchanger and coil. Make sure there are no zone dampers before the supply air sensor. Connect the supply air sensor to the zone panel as shown.
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 panel is 35 VA at
24 VAC.
Configuration
Use the following instructions to configure the 3 Zone Control Panel.
- Open J1 jumper for dual transformer installations.
- Open J2 short cycle protection jumper for system test.
- Press ▲ and then press ▲ to raise or ▼ to lower the Hi Temp cutout.
- Press ▼ and then press ▲ to raise or ▼ to lower the Low Temp cutout.
- Press ▲ and ▼ at the same time to adjust purge time. Press ▲ to raise or ▼ to lower the purge time.
System Checkout
After the wiring and configuration is complete, use the following checklist to verify the panel operation is correct.
- [ ] Make sure the Emergency Heat Switch is in the Off (right) position.
- [ ] Open jumper J2 by moving cap from both pins to only one pin.
- [ ] Use table and diagram in section 4 of this installer guide or inside the zone panel cover to verify DIP switches are set properly.
- [ ] Make sure the supply temp sensor is wired to terminals SA1 and SA2. The zone dampers will not close if the supply sensor is missing.
- [ ] Make sure no zones are calling by turning off all thermostats.
- [ ] Apply 24 VAC power to the panel.
- [ ] Verify green power LED near 24 VAC terminals is lit.
- [ ] Verify green heartbeat LED in middle of panel is pulsing.
- [ ] Verify all 3 zone LEDs near damper terminals are green.
- [ ] Verify supply temp display shows current plenum temperature.
Operation
The 3 Zone Control Panel has LEDs and a built-in display to tell the installer and homeowner the current operating mode of the panel. Refer to Figure 5 and the following descriptions of the panel LEDs for operation information.
LED Display Panel
- Supply Temp: Shows the current air supply temp. Use to set Hi/Lo temp limit. If flashing, check supply air sensor connection.
- Hi Temp: Press ▲ to display Hi temp cutout setting. Press ▲ to raise or ▼ to lower Hi temp setting.
- Lo Temp: Press ▼ to display Lo temp cutout setting. Press ▲ to raise or ▼ to lower Lo temp setting.
- Purge: System uses intelligent purge to maximize comfort and energy savings. Press ▼ and ▲ to display purge time. Press ▲ to increase or ▼ to decrease purge time.
- Delay: Supply air temperature is outside the Hi/Lo temp cutout. System has turned off the equipment except the fan.
