Troubleshooting

• Blank Display: Check 18-32 VAC; cycle power.
  
• No Heat/Cool: Verify mode/setpoint, wiring; test mode.
  
• E0 Error: Thermistor issue; replace.
  
• E4 Error: Voltage out of range; check transformer.
  
• TOV Not Working: Ensure programmable mode (#14=1); check lockouts.
  
• Schedule Issues: Re-edit periods; verify day selection.
  
• Erratic: Cycle power; check location.
  
• Persistent: Contact Trane service.
