Operation Instructions

Initial Setup

1. Turn Off Power: Turn off power to the heating/air conditioning system.
2. Mount Panel: Mount near HVAC equipment, level for appearance. Use base as template, drill holes 4.5” apart, attach with screws/anchors.
3. Configure System:

• Open J1 for dual transformer installations.
• Open J2 for system test (replace for short cycle protection).
• Set DIP switches per system requirements (refer to table/diagram).

Operating the Controller

1. Status LEDs: Heartbeat flashes once/second; RH/RC lit if powered; 24V Power lit; Damper green (open)/red (closed).
2. Zone Operation: No calls: all dampers open. Calls: corresponding dampers open, others close.
3. Purge Cycle: 90 seconds at end of call; no new calls answered.
4. Staging: Automatic based on time.
5. Emergency Heat: Switch to ON for heat pumps; cooling calls ignored.
Note: Use with compatible thermostats and dampers.

Temperature Display Adjustment

Not applicable; this is a zone controller without temperature display. Temperature control via connected thermostats.

Troubleshooting

• No Operation: Ensure Emergency Heat off, J2 open for test, DIP switches correct, no zones calling, power LED lit.
  
• No Heat/Cool: Verify thermostat calls, damper LEDs, air flow. Test zones individually.
  
• Fan Constant: Check fan control settings, wiring.
  
• Erratic Operation: Check voltage, fuse, wiring. Reset power.
  
• LED Issues: Heartbeat not flashing: power/wiring issue. Damper LEDs wrong: check damper wiring/power.
  
• Buttons/Switches Not Working: Verify connections; contact support.

Installation Instructions

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

Remove Old Controller

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

Installing New Controller

1. Mount base near HVAC, level, drill holes, secure.
2. Wire panel: Connect thermostats (Y, G, W/O/B, R, C per zone), HVAC equipment, dampers, transformer.
3. Configure jumpers/DIP switches.
4. Push excess wire back.
5. Apply power, test system.

Battery Location

• Not applicable; hardwired only, 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 for dampers. Use slave relay if over 35 VA. Do not short terminals.
