Operation Instructions

Initial Setup

1. Power On: Apply 24 VAC; performs power-up sequence (full screen, firmware, tests).
2. Configure: Remove cover, hold configuration button 3s; adjust options (#01-18) with Up/Down/Left/Right; exit after 10 min.
3. Set Modes: Press Mode/Fan; select with Up/Down.
4. Calibrate: Use remote sensor if needed; verify via test mode.

Home Screen Navigation

1. Display: Current temp, setpoint, mode icons (heat/cool/auto/off), fan (auto/on), lock symbol.
2. Controls: Up/Down for adjustments; Mode/Fan buttons for selection; Hold Up/Down 3s to toggle display (temp/setpoint/outdoor).
3. Indicators: Wrench for config/test; Error codes (E0-E7).

Operating Modes

1. Heat: Press Mode > Up/Down to Heat; raise setpoint; flame icon.
2. Cool: Press Mode > Up/Down to Cool; lower setpoint; snowflake icon.
3. Auto: Press Mode > Up/Down to Auto; deadband enforced.
4. Off: Press Mode > Up/Down to Off; no operation.
5. Fan: Press Fan > Up/Down to Auto/On.

Settings Screen

1. Configuration: Hold config button 3s; scroll options (e.g., #01 system type, #07 resolution, #12 deadband).
2. Lock: Hold Up/Down 4s in mode to lock/unlock.
3. Test Mode: Hold config button twice; test heat/cool/fan/thermistor.
4. Reset: Cycle power; defaults via #18.

Advanced Features

1. Cycling: Configurable CPH for efficiency.
2. Deadband: 2-9°F separation in Auto.
3. Compressor Protection: 5-10 min off time.
4. Remote Sensor: For control/lockout/display.

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.
  
• Erratic: Cycle power; check location.
  
• Persistent: Contact Trane service.

Installation Instructions

Warning: Qualified personnel only. Disconnect power; discharge capacitors.

Pre-Installation
