Operation Instructions

Initial Setup

1. Turn Off Power: Always turn off power to the heating/air conditioning system prior to installing or adjusting the Zone Panel.
2. Wire Panel: Wire the entire panel before applying transformer power.
3. Configure System:

Press SETUP for 3 seconds to enter menu.
Use SELECT to change values, NEXT to advance, HOLD FOR BACK for 3 seconds to go back, HOLD FOR EXIT for 3 seconds to exit.
Set options like FAN, PURGE, SA SENS, DEG, PLENUM HI/LO LIMIT, SCP, G2 ZONES, PRIORTY, OP MODE.

Operating the Controller

1. LED Indicators: Panel Power (Green flashing), Equipment (Rh, Rc, Y, G, G2, W), Thermostat (R, Y, W, G per zone), Dampers (Red closed/Green open).
2. Display: Shows HEAT CALLS, COOL CALLS, FAN CALLS, PLENUM TEMP (if sensor enabled).
3. Zone Operation: Dampers open on calls; all open if no calls. Purge at end of call.
4. Staging: Automatic based on configuration.
Note: Use with compatible thermostats and dampers. Plenum sensor protects against high/low temps.

Temperature Display Adjustment

Configure temperature scale (°F/°C) in setup menu under DEG. Changing resets plenum limits. No direct calibration; use separate thermometer for verification if needed.

Troubleshooting

No Operation: Check power LED, configuration, zone calls.
No Heat/Cool: Verify thermostat calls, damper LEDs, airflow. Test zones.
Fan Constant: Check fan control settings, wiring.
Erratic Operation: Check voltage, fuse, wiring. Reset panel.
Error Conditions: PLENUM HI (heating off, fan on), PLENUM LO (cooling off, fan on), Plenum Sensor Bad (disable stages/sensor).
System Checkout: Press TEST for 3 seconds; test heating, cooling, fan, dampers.
Reset: Press reset once to restart, hold 5 seconds for factory defaults.

Installation Instructions

Warning: Turn off power before installation. For experienced technicians only. Use only with described systems; conform to local codes. Provide disconnect and overload protection.

Remove Old Controller

Turn off power. Disconnect wiring, note connections. Remove old mounting hardware and controller.

Installing New Controller

Mount near HVAC equipment in any orientation (wall, stud, truss, plenum), level for appearance. Use base as template, drill holes, secure with screws/anchors.
Connect thermostats (R, W, Y, G per zone), equipment (Rh, Rc, Y, G, G2, W), dampers (PO/PC per zone), optional plenum sensor, dedicated transformer (R, C).
Configure via setup menu.
Push excess wire back.
Apply power, test system using checkout mode.

Battery Location

Not applicable; no batteries.

Power Options

Hardwired with dedicated 24 VAC transformer.

Controller Power Method	Description
Hardwired	Runs on 24 VAC from zoning transformer.

Caution: Size transformer appropriately. Use slave relay if over max VA. Do not short terminals.
